One of the best ways to enhance that vibe, and potentially boost performance, is by bumping up the size of your rear tire. This guide will walk you through everything you need to know, from the why to the how, so you can make an informed decision and hopefully, get your Bobber looking even more badass. We'll cover why you might want a bigger tire, the potential benefits, the challenges you might face, and the specific steps involved in making the swap. Buckle up; it's going to be a fun ride!

Why Upgrade Your Indian Scout Bobber's Rear Tire?

So, why even bother upgrading your Indian Scout Bobber's rear tire? Well, there are a few compelling reasons. A bigger tire can dramatically change the look of your bike, giving it a more muscular and imposing stance. This is purely aesthetic for some, and let's face it, the Bobber is all about style. But there's more to it than just looks. A wider tire can potentially improve grip, especially when cornering or accelerating. More rubber on the road means more contact, which can translate to better traction. This can be particularly noticeable if you ride aggressively or in varied weather conditions. Furthermore, changing the tire size can sometimes influence handling. A wider tire might make the bike feel more stable at higher speeds, although it could also slightly impact its agility. It's a trade-off, and the effect will depend on the specific tire size you choose and your riding style. Think about it: the stock tire is good, but is it perfect for what you want? A larger tire can also offer a more comfortable ride by absorbing more bumps and road imperfections, which can make those longer rides a bit more enjoyable. The change can be surprisingly significant in terms of feel. Finally, personal preference plays a huge role. Maybe you simply dig the look of a fatter tire, which is totally understandable! It's your bike, after all. Ultimately, the decision comes down to a combination of aesthetics, performance, and personal preference. It's about tailoring your Indian Scout Bobber to fit your vision and how you like to ride. Let's make this Indian Scout Bobber stand out from the crowd.

Aesthetics and Performance Benefits

Let's break down the advantages a little further. Aesthetically, a bigger rear tire on a Bobber instantly makes it look meaner and more aggressive. It fills out the fender, giving the bike a more substantial presence on the road. The Bobber is already a head-turner, but a fatter tire just takes it to the next level. This visual upgrade can be a game-changer if you want to make a statement. The visual impact alone is often enough to convince riders to make the change. From a performance standpoint, the increased contact patch – the area of the tire that touches the road – can significantly improve grip. This is especially useful during acceleration, where the bike's power is transferred to the rear wheel. More grip means less wheel spin and quicker acceleration. It can also help when braking, providing more surface area to slow the bike down effectively. When cornering, a wider tire can offer increased stability and confidence. You'll feel more planted, which encourages you to lean into the turns with more conviction. This enhanced grip is especially beneficial on twisty roads or when riding in less-than-ideal conditions. Keep in mind that the degree of these benefits will vary depending on the tire size, the tire compound, and your riding style. It's not just about slapping on the biggest tire you can find; it's about finding the right balance for your needs and preferences.

Choosing the Right Rear Tire Size for Your Indian Scout Bobber

Alright, so you're sold on the idea of a bigger rear tire. Now, let's talk about choosing the right size. This is where things get a little technical, but don't worry, we'll break it down. The first thing to consider is the available space in your swingarm and under your fender. You don't want the tire rubbing against anything, which could lead to damage or, worse, a dangerous situation. You will need to take measurements. Measure the distance from the swingarm to the current tire and from the top of the tire to the fender. From these measurements, you can determine how much extra width and height you have to work with. There are usually limits to how wide you can go without making modifications to the bike, so this is an important step. Research forums, and online communities dedicated to the Indian Scout Bobber can be invaluable. Riders who have already done the upgrade can offer advice on what sizes fit without any modifications. They can also share which tires work well and which ones to avoid. Websites of tire manufacturers also provide size charts that show the dimensions of their tires. These can be helpful for comparing different tire sizes and making sure they'll fit on your bike. In terms of actual tire sizes, common upgrades often include moving from the stock tire size (typically a 150/80B16 or similar) to a 160/80B16, 170/80B16, or even larger. However, keep in mind that going too wide can negatively impact handling. You might find the bike feels less nimble or takes more effort to lean into turns. So, finding the sweet spot is key. Pay attention to the aspect ratio as well. This number (e.g., the 80 in 150/80B16) indicates the height of the tire's sidewall as a percentage of its width. Changing the aspect ratio will affect the overall diameter of the tire, which in turn can affect your speedometer reading. When selecting a tire size, it's also important to consider the type of tire. Are you looking for a tire with more grip, better handling, or longer wear? Think about your riding style and the conditions you typically ride in. Do you mostly cruise on the highway, or do you enjoy carving up twisty roads? Do you ride in wet weather frequently? This will help you narrow down your choices and select a tire that best suits your needs. The tire compound is the most crucial part.

Tire Types and Considerations

There are several types of tires available for your Indian Scout Bobber, each with its own advantages and disadvantages. Sport tires offer maximum grip and performance, making them ideal for aggressive riding and cornering. They typically have a softer compound, which provides excellent traction but wears out faster. If you're looking for the ultimate in handling, a sport tire might be the way to go. Touring tires, on the other hand, are designed for longevity and comfort. They have a harder compound, which means they last longer, but they may not offer as much grip as sport tires. If you do a lot of long-distance riding, a touring tire is a good option. Cruiser tires are a popular choice for Bobbers, as they offer a good balance of grip, handling, and wear. They often have a classic look that complements the Bobber's style. Cruiser tires provide good performance for both city riding and weekend trips. All-season tires offer a versatile option, providing decent performance in a variety of conditions, including wet weather. They typically have a tread pattern designed to channel water away from the contact patch. If you ride in different types of weather, an all-season tire is a good choice. Choosing the right tire also involves considering the load rating and speed rating. The load rating indicates the maximum weight the tire can carry, and the speed rating indicates the maximum speed at which the tire can be safely used. Make sure the tire you choose has a load rating and speed rating that meet or exceed the requirements for your bike. The tire's tread pattern also plays a significant role. It affects the tire's grip, handling, and water-clearing capabilities. Look for a tread pattern that's appropriate for your riding style and the conditions you typically ride in. The tread pattern should effectively channel water away from the contact patch to maintain grip in wet conditions. Remember that choosing the right tire is a balance of performance, aesthetics, and practicality. Consider your riding style, the conditions you ride in, and your budget to make the best choice for your Indian Scout Bobber.

The Installation Process: Swapping Your Rear Tire

Okay, so you've done your research, chosen your new tire, and are ready to get your hands dirty. Let's walk through the installation process of swapping your rear tire. This isn't a job for the faint of heart, but with the right tools and a little patience, it's definitely doable. First, gather your tools. You'll need a motorcycle jack or lift, tire irons, a bead breaker, a wheel balancer, a torque wrench, sockets and wrenches, and potentially a new valve stem. Make sure you have all the necessary tools before you start. Next, prepare your bike. Securely lift your Indian Scout Bobber using a motorcycle jack or lift. Make sure the bike is stable and won't tip over. It's also a good idea to disconnect the negative terminal of the battery for safety. Now, remove the rear wheel. Loosen the axle nut and then remove the axle. Carefully slide the wheel out of the swingarm. If your bike has a belt drive, be extra careful not to damage the belt. Once the wheel is off, you'll need to remove the old tire. Use a bead breaker to break the bead of the tire from the rim. Then, use tire irons to carefully pry one side of the tire off the rim. Once one side is off, you can work your way around the rim to remove the other side. Be careful not to scratch the rim during this process. Before installing the new tire, inspect the rim for any damage or wear. Also, check the valve stem and replace it if necessary. Now, mount the new tire onto the rim. Lubricate the bead of the new tire with tire mounting lubricant or soapy water. Then, carefully work the tire onto the rim, using tire irons if needed. Once the tire is mounted, inflate it to the recommended pressure. Reinstall the rear wheel. Carefully slide the wheel back into the swingarm, making sure the axle goes through. Tighten the axle nut to the manufacturer's specifications using a torque wrench. Check your owner's manual for the correct torque specifications. After the tire is installed, make sure to balance it. An unbalanced tire can cause vibrations and affect handling. If you don't have a wheel balancer, take your wheel to a local motorcycle shop to have it balanced. Finally, inspect your work. Double-check all bolts and nuts to make sure they're properly tightened. Check the tire pressure and adjust it as needed. Go for a test ride to make sure everything feels right. Listen for any unusual noises or vibrations. This is the time to check the clearance between the tire and the fender. Be sure that everything is working properly before hitting the road. Congratulations! You've successfully swapped your rear tire!

Step-by-Step Guide for Tire Replacement

Let's break down the installation process further with a more detailed, step-by-step guide. Step 1: Prep and Safety. Park your Indian Scout Bobber on a level surface. Ensure the engine is cool. Disconnect the negative terminal of the battery. This is a crucial safety step to prevent any electrical mishaps. Gather your tools and materials, which should include a motorcycle jack, a socket set, a torque wrench, tire levers, a bead breaker (or a friend with strong legs!), tire mounting lubricant, a tire pressure gauge, and potentially a new valve stem. Step 2: Lifting the Bike. Position your motorcycle jack under the frame, ensuring it's securely placed. Raise the bike until the rear wheel is off the ground, providing enough clearance to remove it. Step 3: Removing the Rear Wheel. Loosen the axle nut using the appropriate socket. Then, carefully remove the axle. Be prepared to catch the wheel. Gently slide the rear wheel out of the swingarm. If your Bobber has a belt drive, take extra care to avoid damaging the belt during this process. Step 4: Breaking the Bead. Use a bead breaker to break the seal between the tire bead and the rim. This can also be done manually using your feet, but a bead breaker makes it much easier. You may also be able to do this with tire levers, working slowly around the tire. Step 5: Tire Removal. Using tire levers, carefully pry one side of the tire off the rim. Work your way around the rim, using the tire levers to lift the tire over the edge. Once one side is off, repeat the process for the other side. This can be the trickiest part, so take your time and avoid scratching the rim. Step 6: Rim Inspection and Preparation. Inspect the rim for any signs of damage, such as dents or corrosion. Clean the rim thoroughly, removing any dirt or debris. If your valve stem is old or damaged, now's the time to replace it. Step 7: Tire Mounting. Lubricate the bead of the new tire with tire mounting lubricant. This will help the tire slide onto the rim. Position the tire on the rim, aligning the directional arrow (if applicable) with the direction of rotation. Using tire levers, carefully work the tire onto the rim. This may require some effort, but be patient. Step 8: Tire Inflation and Seating. Inflate the tire to the recommended pressure, which can usually be found on the tire sidewall. You should hear a 'pop' sound as the tire bead seats against the rim. Make sure the tire bead is seated evenly around the entire circumference of the rim. Step 9: Balancing. If you have a wheel balancer, now is the time to balance the wheel. If not, take the wheel to a local motorcycle shop for balancing. Balancing is critical for a smooth ride. Step 10: Wheel Reinstallation. Carefully slide the wheel back into the swingarm, aligning the axle with the axle slot. Insert the axle and tighten the axle nut to the manufacturer's specified torque. Use a torque wrench to ensure proper tightening. Step 11: Final Checks and Test Ride. Reconnect the negative terminal of the battery. Check the tire pressure again. Inspect the tire clearance to the fender and swingarm. Go for a short test ride, checking for any unusual noises, vibrations, or handling issues. Then you're all set!

Potential Challenges and Considerations

While swapping your Indian Scout Bobber's rear tire can be a rewarding project, there are some potential challenges and considerations to keep in mind. One of the biggest hurdles is space. As mentioned earlier, you need to ensure there's enough clearance between the tire and the swingarm, the fender, and any other components. This is why careful measurement is so crucial before you even buy a tire. If you try to fit a tire that's too wide, it could rub, leading to premature tire wear or, worse, a dangerous situation where the tire could fail. Another challenge is the handling characteristics of the bike after the swap. A wider tire can change how the bike feels in turns, potentially making it less agile or requiring more effort to lean into corners. This isn't necessarily a bad thing, but it's something to be aware of and to consider when choosing a tire size. The weight of the new tire can also be a factor. A heavier tire can affect acceleration and braking performance. Keep this in mind when making your choice. Also, remember that modifications to the fender or swingarm might be necessary to accommodate a larger tire. This could involve trimming the fender or adding spacers to the swingarm. These modifications require more advanced skills and tools. It's important to understand your mechanical abilities and to be realistic about what you can handle. If you're not comfortable doing these types of modifications, it's best to seek professional help. Finally, be prepared for some trial and error. You might not get the perfect fit or handling characteristics on the first try. You might need to experiment with different tire sizes or brands to find the one that works best for your riding style and the specific setup of your bike. Patience and a willingness to learn are essential. If you encounter any problems, don't hesitate to consult with experienced riders or a professional motorcycle mechanic. They can offer valuable advice and help you troubleshoot any issues. Make sure the tire is properly balanced after the install; otherwise, it could have an effect on your handling.

Dealing with Rubbing and Handling Changes

Let's delve deeper into the specific challenges of rubbing and handling changes. Rubbing is one of the most common issues when installing a larger rear tire. The tire might rub against the swingarm, the fender, or other components of your bike. This not only causes damage to the tire and the bike but can also be dangerous. Before installing the tire, carefully measure the available space and compare it to the tire's dimensions. If you anticipate rubbing, there are a few things you can do. You might be able to adjust the fender or add spacers to create more clearance. Some riders have had success with slightly modifying their fender or even swapping it out for a different model. However, these modifications can be complicated and may require welding or other specialized tools. Be cautious and research any modifications thoroughly before attempting them. You should always ensure that any modifications you make don't compromise the structural integrity of your bike. If the tire rubs on the swingarm, it might be possible to use a thinner profile tire or spacers. Seek advice from experienced mechanics or online forums. Handling changes are another factor to consider. A wider tire can affect how the bike feels in turns. It might make the bike less agile or require more effort to lean into corners. This is due to the increased contact patch, which provides more grip but can also make the bike feel less responsive. If you're used to the nimble handling of the stock tire, it might take some time to get used to the feel of a wider tire. To minimize the impact on handling, consider choosing a tire with a profile similar to the stock tire, even if it's wider. You could also experiment with tire pressures to find a setting that provides a good balance of grip and handling. Your riding style will also play a role. If you ride aggressively, you might prefer a wider tire for its enhanced grip and stability. If you primarily commute or cruise, you might prefer a tire that's slightly narrower for better agility. Remember that there is no perfect solution, and finding the right balance will likely involve some trial and error. Pay close attention to how the bike feels after the tire swap and adjust your riding style as needed. Don't be afraid to experiment with different settings and consult with other riders to get their opinions. Safety always comes first, so if you're ever concerned about the handling of your bike, consult a professional mechanic. The change in handling may take some getting used to.
