Hey guys, if you're rocking a 2020 Jeep Gladiator Overland, you're probably already aware that it's a beast. This truck is designed for adventure, from cruising down the highway to tackling off-road trails. One of the most important aspects of your Gladiator's performance and appearance is the tire size. Getting the right size not only enhances your truck's capabilities but also improves its aesthetics and overall driving experience. In this guide, we'll dive deep into the 2020 Gladiator Overland tire size options, helping you choose the perfect set for your needs. We'll cover everything from the stock tire size to the maximum size you can fit with and without modifications, along with recommendations and considerations for different types of driving. So, buckle up, and let's get rolling!

Understanding 2020 Gladiator Overland Tire Sizes

When it comes to the 2020 Gladiator Overland tire size, it's important to start with the basics. The stock tire size for the Overland trim is typically LT285/70R17. This size offers a good balance of on-road comfort and off-road capability. The "LT" designation indicates that these are Light Truck tires, built to handle the rigors of heavier loads and tougher terrains. The "285" refers to the tire's width in millimeters, "70" is the aspect ratio (the height of the sidewall as a percentage of the width), and "17" is the wheel diameter in inches. Now, this is a starting point, and knowing this initial setup will make understanding what comes next a lot easier. But the world of tire sizes can be confusing, right? So let’s break it down further. You'll encounter terms like "plus sizing" – this means increasing the tire size from the stock. Doing this can give your Gladiator a more aggressive look and may improve its off-road performance. However, there are things to think about before changing the tire size.

Changing your tire size can impact several aspects of your truck's performance. For example, a larger tire can increase ground clearance, allowing you to clear obstacles more easily. But, larger tires can also affect your fuel economy, acceleration, and speedometer accuracy. That is why it’s super important to be fully informed before making the switch. In addition, it is essential to consider the load rating of the tires. The load rating indicates the maximum weight the tire can support. If you plan on carrying heavy loads or doing a lot of towing, ensure that your tires have an appropriate load rating.

Beyond the numbers, the type of tire is also important. The 2020 Gladiator Overland comes with all-terrain tires. These tires are designed to perform well in a variety of conditions, from pavement to dirt trails. They offer a good balance of on-road comfort and off-road traction. However, if you plan on doing serious off-roading, you might consider upgrading to mud-terrain tires, which provide even more aggressive tread patterns and better grip in muddy or rocky conditions. But, these types of tires will have a more noisy ride and might wear out more quickly when used on paved roads.

Maximum Tire Size Without Modifications

Alright, so you want to upgrade your tires, but you don't want to mess with lifting your Gladiator? No problem, 2020 Gladiator Overland tire size upgrades are possible without any modifications. Generally, you can fit up to a 33-inch tire without any modifications like a lift kit or trimming. This is a common upgrade that provides a more aggressive look and a bit more ground clearance without requiring extensive changes to your truck. A good option is a 285/75R17 tire. This size is slightly taller and wider than the stock tires, and will give your Gladiator a more substantial appearance. This tire size upgrade is great for a little extra clearance without a lift. It's a great option for those who want to enhance the look and capability of their Gladiator without the added cost and complexity of a lift kit. The most important thing here is to ensure that your chosen tires do not rub against the wheel wells or other components when you are turning or flexing the suspension. While this size typically fits without issues, it's always a good idea to check for clearance.

So, if you're not planning on off-roading, you probably want to stick to these options. When selecting tires, look for brands that specialize in all-terrain tires. You'll find that there are many options that will offer you a good balance of on-road comfort and off-road grip. The great thing about the 33-inch tire size is that it's a sweet spot. However, keep in mind that even though the 33-inch tire size is a pretty safe bet, it's still a good idea to test-fit the tires before you fully commit to them.

Maximum Tire Size With Modifications

Now, if you're looking to take your Gladiator to the next level, you might consider modifications. With a lift kit, you can fit even larger tires, further enhancing your truck's off-road capabilities and aggressive stance. Now, what's the largest 2020 Gladiator Overland tire size you can fit with modifications? Well, with a lift kit and potentially some minor trimming, you can typically fit tires up to 35 inches in diameter. This is a significant upgrade from the stock tire size and offers a substantial increase in ground clearance and off-road performance. However, going with 35-inch tires requires more than just a lift kit.

To accommodate 35-inch tires, you'll need to install a lift kit. Lift kits come in various heights, from a few inches to several inches. Choose a lift kit that suits your off-road needs and driving style. Additionally, you might need to make some adjustments to your Gladiator, such as trimming the fender flares or modifying the inner fender liners. These modifications ensure that the tires don't rub against the body or suspension components during articulation. Furthermore, you will want to think about regearing your axles. Larger tires can change your gear ratio, affecting your acceleration and fuel economy. Regearing your axles can help restore your truck's performance. Also, stronger axles will be a great idea. Given the extra strain that larger tires put on your drivetrain, you might consider upgrading your axles for increased durability.

This kind of upgrade is for serious off-roaders and those who are looking for a more aggressive look. Keep in mind that installing a lift kit and fitting larger tires can affect your truck's handling and stability. It's important to choose quality components and have the installation performed by a professional. Now, the 35-inch tire size is a pretty serious upgrade, so you’ll need to make sure you're ready to make that kind of commitment. But if you are, the results can be pretty spectacular.

Tire Recommendations

Choosing the right tires for your 2020 Gladiator Overland can be overwhelming with all the options out there. However, here are a few popular and well-regarded tires that are worth considering, keeping in mind the 2020 Gladiator Overland tire size constraints. For the stock size or a slight upgrade without modifications (e.g., 285/70R17 or 285/75R17), the BFGoodrich All-Terrain T/A KO2 is a classic choice. It's known for its excellent on- and off-road performance, durability, and aggressive look. This tire offers a great balance for daily driving and occasional off-roading. Another strong contender is the Falken Wildpeak AT3W. This tire provides excellent all-weather performance, including good snow and wet traction, and is known for its quiet ride and long tread life.

If you are planning to get a 35-inch tire size and are serious about off-roading, the Nitto Trail Grappler is a great choice. It offers aggressive off-road performance, with a relatively quiet ride for a mud-terrain tire. This tire is ideal for those who spend a lot of time on trails. Another great option is the Toyo Open Country M/T. The Open Country M/T is known for its aggressive tread pattern, durability, and excellent off-road traction. This is a premium mud-terrain tire that can handle the toughest terrains. However, they can be louder on the road than all-terrain tires. Remember, your driving habits and the terrain you frequent should guide your final selection. It's always best to research different brands and read reviews to ensure you're getting the best tire for your specific needs.

Important Considerations

Before you make your 2020 Gladiator Overland tire size selection, keep a few important factors in mind. First off, consider your driving style and the type of terrain you'll be encountering most often. If you primarily drive on paved roads and do occasional light off-roading, all-terrain tires will likely be sufficient. But, if you frequently tackle challenging off-road trails, mud-terrain tires might be a better choice. In addition, always check your wheel's specifications. Make sure your chosen tires are compatible with your wheels' width, offset, and bolt pattern. Installing tires that are not compatible with your wheels can lead to safety issues and damage to your truck.

Moreover, pay attention to the speed rating of the tires. The speed rating indicates the maximum speed at which the tire can safely operate under ideal conditions. Select tires with a speed rating that meets or exceeds your typical driving speeds. Make sure to consider the load rating. The load rating is super important because it indicates the maximum weight the tire can carry. It is absolutely necessary to choose tires with an appropriate load rating for your Gladiator, considering the weight of the vehicle and any potential cargo. Finally, it’s necessary to recalibrate your speedometer. When you change your tire size, your speedometer will likely be inaccurate. Recalibrating your speedometer ensures that your speed readings are accurate. You can usually do this by using a programmer or by visiting a professional.

Conclusion

Choosing the right 2020 Gladiator Overland tire size is a crucial decision that affects the look, performance, and capability of your truck. By understanding the stock tire size, exploring the options for upgrades with and without modifications, and considering the factors outlined in this guide, you can make an informed decision that will enhance your Gladiator's performance. Whether you're looking for a slight improvement in aesthetics and ground clearance or a more aggressive off-road setup, there's a perfect tire size out there for your Overland. So, go out there, do your research, and choose the perfect tires to make your Gladiator truly stand out from the crowd! Have fun and be safe on the trails, guys! Enjoy your ride.
