Understanding Stock Tire Sizes for the 2019 Ram 1500 Classic

Alright, let's start with the basics. Knowing the original tire sizes that came with your 2019 Ram 1500 Classic is the best starting point. These sizes are designed to provide the optimal balance of ride comfort, handling, and load-carrying capacity. Typically, the 2019 Ram 1500 Classic came with a few different tire size options, depending on the trim level and any optional packages that were added. For example, the most common sizes you might find are:

• 265/70R17: This size is often found on the base trim levels.
• 275/60R20: A popular choice for higher trim levels, offering a good blend of style and performance.
• 275/60R18: Another common size that provide you a perfect driving experience.

Now, what do these numbers even mean? Let's break it down:

• The first number (e.g., 265 or 275) indicates the tire width in millimeters. So, a 265 tire is 265 millimeters wide.
• The second number (e.g., 70 or 60) is the aspect ratio. This is the height of the tire sidewall as a percentage of the tire width. For example, a 70 aspect ratio means the sidewall height is 70% of the tire's width.
• The "R" simply stands for radial, which refers to the tire's construction type.
• The last number (e.g., 17, 18, or 20) is the wheel diameter in inches. This tells you the size of the wheel that the tire is designed to fit.

Knowing these stock sizes is crucial because they ensure your speedometer reads correctly, your truck handles as it should, and you avoid any clearance issues with the suspension or body. If you're unsure which size your truck originally came with, check the sticker on the driver's side doorjamb. It's usually listed there, along with other important information like the recommended tire pressure. You can also consult your owner's manual for this info. Seriously, guys, don't skip this step – it's the foundation for everything else we'll discuss!

Decoding Tire Sidewall Markings

Okay, so you've found those numbers on your tires, but what else do all those letters and symbols mean? Decoding tire sidewall markings can seem like deciphering a secret code, but once you understand the basics, it's actually pretty straightforward. Besides the size, here are some other key markings you'll typically find:

• Load Index: This is a numerical code that indicates the maximum weight each tire can carry when properly inflated. You'll need to look up this number on a load index chart to find the actual weight in pounds or kilograms. It's super important to ensure your new tires have a load index equal to or greater than the original tires to maintain your truck's load-carrying capacity and safety.
• Speed Rating: This is a letter code that indicates the maximum speed at which the tire can safely operate. Again, you'll need to consult a speed rating chart to find the actual speed in miles per hour or kilometers per hour. It's generally recommended to stick with the speed rating specified by the vehicle manufacturer, or higher. Going lower could compromise safety, especially at high speeds.
• DOT Code: This is a series of letters and numbers that indicate the tire's manufacturer, plant code, tire size, and date of manufacture. The last four digits of the DOT code tell you when the tire was made – the first two digits represent the week, and the last two represent the year. For example, if the last four digits are "2023", the tire was manufactured in the 20th week of 2023. This is helpful to know because tires age over time, even if they're not being used. Most experts recommend replacing tires that are more than six years old, regardless of tread depth.
• M+S (Mud and Snow): This marking indicates that the tire meets certain standards for mud and snow performance. It doesn't necessarily mean it's a dedicated winter tire, but it should offer better traction in slippery conditions than a standard all-season tire. If you live in an area with severe winter weather, you might want to consider a tire with the three-peak mountain snowflake symbol (3PMSF) – this indicates that the tire has been tested and certified for severe snow performance.

Understanding these markings will not only help you choose the right tires but also give you a better understanding of your current tires' capabilities and limitations. Don't be intimidated by the jargon – take the time to learn what it all means, and you'll be a much more informed and confident tire buyer.

Considering Tire Upgrades and Alternatives

Okay, so you know the stock tire sizes and how to decode those sidewall markings. Now, let's talk about upgrading or changing things up! Maybe you want a more aggressive look, better off-road performance, or simply a different ride feel. There are plenty of reasons to consider alternative tire sizes, but it's crucial to do your homework before you make any changes. Here's what you need to consider:

• Lift or Leveling Kits: If you're planning to install larger tires, you'll likely need a lift or leveling kit to create enough clearance. Without one, the tires could rub against the suspension or body, causing damage and compromising safety. A leveling kit raises the front of the truck to match the rear, while a lift kit raises both the front and rear for even more clearance. The amount of lift you need will depend on the tire size you want to run.
• Wheel Offset: The wheel offset is the distance between the wheel's mounting surface and its centerline. Changing the wheel offset can affect how the tires sit in the wheel wells and whether they rub against the suspension or body. A negative offset will push the wheels outward, while a positive offset will pull them inward. Be careful when changing the offset, as it can also affect the truck's handling and stability.
• Speedometer Calibration: If you significantly change the tire size, it can affect your speedometer's accuracy. Larger tires will make your speedometer read slower than your actual speed, while smaller tires will make it read faster. To correct this, you may need to recalibrate your speedometer using a programmer or tuner. Some shops can also do this for you.
• Load and Speed Ratings: As mentioned earlier, it's crucial to maintain or exceed the original tires' load and speed ratings. Don't compromise safety for the sake of appearance. Make sure the new tires can handle the weight and speed requirements of your truck.
• Fuel Efficiency: Larger, heavier tires can negatively impact your fuel efficiency. They require more energy to turn, which means your engine has to work harder. If fuel economy is a concern, you might want to stick with a tire size that's close to the original.

Before making any decisions, it's always a good idea to consult with a tire professional. They can help you choose the right tire size and type for your needs and ensure that everything fits properly. They can also advise you on any necessary modifications, such as lift kits or speedometer recalibration.

Where to Find the Right Tires

Alright, you've done your research, considered your options, and you're ready to buy some new tires! But where do you go to find the best selection and prices? Here are a few options:

• Local Tire Shops: Your local tire shops are a great place to start. They often have knowledgeable staff who can answer your questions and help you find the right tires for your truck. Plus, they can usually install the tires for you, which can save you time and hassle.
• Online Retailers: Online retailers like Tire Rack and Discount Tire offer a huge selection of tires at competitive prices. You can often find deals and discounts that you wouldn't find at a local shop. However, you'll need to arrange for installation yourself, which may involve finding a local installer or doing it yourself if you're comfortable with that.
• Dealerships: Your local Ram dealership can also sell tires, but they may not always have the best prices. However, they will have tires that are specifically designed for your truck, and they can ensure that everything is installed correctly.
• Warehouse Clubs: Clubs like Costco and Sam's Club also sell tires at discounted prices. However, their selection may be limited, and you may need to be a member to purchase them.

When shopping for tires, be sure to compare prices and read reviews. Look for tires that offer a good balance of performance, durability, and value. And don't be afraid to ask questions – the more informed you are, the better decision you'll make.

Maintaining Your Tires

Once you've got those new tires on your 2019 Ram 1500 Classic, the job's not over! Proper maintenance is essential to maximize their lifespan and ensure your safety. Here are some key things to keep in mind:

• Regularly Check Tire Pressure: Maintaining the correct tire pressure is crucial for optimal performance, fuel efficiency, and tire wear. Check your tire pressure at least once a month, and always before a long trip. You can find the recommended tire pressure on the sticker on the driver's side doorjamb or in your owner's manual. Use a reliable tire pressure gauge, and inflate or deflate your tires as needed. Remember that tire pressure can fluctuate with temperature, so check it when the tires are cold (i.e., before you've driven the truck).
• Rotate Your Tires: Tire rotation involves moving the tires from one position on the vehicle to another to ensure even wear. This can significantly extend the life of your tires. Consult your owner's manual for the recommended rotation pattern and frequency. Typically, tires should be rotated every 5,000 to 8,000 miles.
• Check Tire Tread Depth: Adequate tread depth is essential for maintaining traction, especially in wet or snowy conditions. You can check your tire tread depth using a tread depth gauge or the penny test. Insert a penny into the tread groove with Lincoln's head facing down. If you can see the top of Lincoln's head, your tires are worn out and need to be replaced.
• Inspect for Damage: Regularly inspect your tires for signs of damage, such as cuts, bulges, or uneven wear. If you notice any damage, have your tires inspected by a professional. Ignoring damage can lead to tire failure, which can be dangerous.
• Proper Storage: If you're storing tires, keep them in a cool, dry place away from direct sunlight and ozone sources (such as electric motors). This will help prevent the rubber from deteriorating.

By following these simple maintenance tips, you can help ensure that your tires last longer and perform optimally. This will save you money in the long run and keep you and your passengers safe.
