Understanding Stock Tire Sizes for the 2019 RAM 1500 Classic

So, you're probably wondering, "What tire size did they put on my 2019 RAM 1500 Classic from the factory?" The answer isn't always a one-size-fits-all, as it depends on the specific trim level and options your truck came with. However, let's break down the most common stock tire sizes you'll find:

• 265/70R17: This is a pretty standard size for many of the base trim levels. The "265" represents the tire width in millimeters, "70" is the aspect ratio (the height of the sidewall as a percentage of the width), "R" indicates it's a radial tire, and "17" is the wheel diameter in inches. This size offers a good balance of ride comfort and capability for everyday driving and light off-road use.
• 275/60R20: You'll often find this size on higher trim levels or those equipped with the optional 20-inch wheels. The slightly wider width (275mm) can provide a bit more grip, and the 20-inch wheel gives your truck a more aggressive look. However, keep in mind that the shorter sidewall (60 aspect ratio) might result in a slightly firmer ride compared to the 17-inch option.
• Other Possible Sizes: While the above two are the most common, there might be other variations depending on specific packages or regional differences. To be absolutely sure, the best place to check is the sticker on your driver's side doorjamb. This sticker contains crucial information about your vehicle, including the recommended tire size and inflation pressures. You can't go wrong by checking there first! Also, your owner's manual will have a detailed list of the original tire sizes that your truck came with. If you're planning to replace your tires with the same size as the originals, knowing this information is crucial. It guarantees that the new tires will fit properly without causing any problems with the vehicle's systems. This includes the speedometer and odometer readings, which are calibrated to the original tire size. Using a different size can throw these readings off, so sticking to the manufacturer's recommendations is generally a good idea. Plus, the original tire size is selected to match your vehicle's performance and safety needs. Switching to a different size might negatively impact handling, braking, and stability, especially in challenging driving conditions. So, for the best results, always refer to the sticker on the doorjamb or the owner's manual to confirm the correct tire size for your 2019 RAM 1500 Classic.

Where to Find Your 2019 RAM 1500 Classic's Tire Size Information

Okay, so we've talked about the common sizes, but how do you actually find out what size tires your specific 2019 RAM 1500 Classic needs? Here are the key places to look:

1. Driver's Side Doorjamb Sticker: This is your best friend when it comes to finding accurate information about your truck. Open your driver's side door and look for a sticker on the doorjamb (the part of the frame where the door latches). This sticker contains a wealth of information, including the original tire size and recommended tire pressure. It's usually labeled clearly, so you shouldn't have trouble finding it.
2. Owner's Manual: Your owner's manual is another great resource. It will list the original tire sizes that came with your truck, along with other important information about tire maintenance and safety. Dig it out of your glove compartment – it's worth its weight in gold!
3. Tire Sidewall: You can also find the tire size printed directly on the sidewall of your existing tires. Just look for a series of numbers and letters like "265/70R17" or "275/60R20." This is a quick and easy way to confirm the size, but keep in mind that if your tires have been replaced previously, they might not be the original size.

Checking these three locations will ensure you have the correct information before you start shopping for new tires. Don't rely on your memory or what someone else tells you – always verify the size yourself!

Considerations When Upsizing Tires on Your 2019 RAM 1500 Classic

Alright, let's say you're thinking about putting some bigger, beefier tires on your 2019 RAM 1500 Classic. Upsizing can definitely give your truck a more aggressive look and improve its off-road capabilities, but there are some things you need to keep in mind before you pull the trigger:

• Lift Kits: In many cases, you'll need to install a lift kit to create enough clearance for larger tires. Without a lift, the tires might rub against the fenders or suspension components, especially when turning or going over bumps. Lift kits come in various sizes, so choose one that's appropriate for the tire size you want to run. A small leveling kit might be enough for a slightly larger tire, while a full suspension lift will be necessary for significantly larger tires.
• Wheel Offset: 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 how they interact with the suspension. If you're upsizing your tires, you might need to choose wheels with a different offset to ensure proper clearance. A negative offset will push the wheels outward, while a positive offset will pull them inward. Be careful not to choose an offset that causes the tires to rub against the fenders or suspension.
• Gearing: Larger tires effectively change your truck's gear ratio. This can impact acceleration, fuel economy, and even towing performance. If you go with significantly larger tires, you might need to re-gear your axles to compensate for the change in gear ratio. Re-gearing will restore some of the lost performance and improve your truck's overall drivability.
• Speedometer Calibration: As we mentioned earlier, changing tire sizes can throw off your speedometer and odometer readings. If you upsize your tires, you'll need to recalibrate your speedometer to ensure accurate readings. This can usually be done with a programmer or by taking your truck to a shop that specializes in speedometer calibration.
• Potential Rubbing: Even with a lift kit and proper wheel offset, there's still a chance that larger tires could rub against the fenders or suspension, especially at full steering lock or when the suspension is fully compressed. Be sure to test fit the tires and check for any signs of rubbing before you hit the road. You might need to trim the fenders or modify the suspension to eliminate any rubbing issues.

Upsizing your tires can be a great way to customize your 2019 RAM 1500 Classic, but it's important to do your research and understand the potential consequences. Talk to a tire professional or off-road specialist to get advice on the best tire size and setup for your needs.

Maintaining Your 2019 RAM 1500 Classic Tires

Once you've got the right tires on your 2019 RAM 1500 Classic, it's important to take care of them to ensure they last as long as possible and provide optimal performance. Here are a few key maintenance tips:

1. Regularly Check Tire Pressure: Maintaining the correct tire pressure is crucial for safety, fuel economy, and tire wear. Check your tire pressure at least once a month, and always before long trips or when carrying heavy loads. You can find the recommended tire pressure on the sticker on your driver's side doorjamb or in your owner's manual. Use a reliable tire pressure gauge to get an accurate reading, and inflate or deflate your tires as needed.
2. Rotate Your Tires: Tire rotation helps to ensure even wear and extend the life of your tires. Follow the tire rotation schedule recommended in your owner's manual, or have your tires rotated every 5,000 to 7,000 miles. Rotating your tires will help to distribute the wear evenly across all four tires, preventing premature wear and tear.
3. Inspect for Wear and Damage: Regularly inspect your tires for signs of wear and damage, such as cuts, bulges, or uneven wear patterns. If you notice any problems, have your tires inspected by a professional. Ignoring these issues can lead to tire failure, which can be dangerous.
4. Balance Your Tires: Unbalanced tires can cause vibrations and uneven wear. Have your tires balanced when you get them rotated, or if you notice any vibrations while driving. Balancing your tires will ensure a smooth and comfortable ride and prevent premature wear.
5. Align Your Wheels: Proper wheel alignment is essential for optimal tire wear and handling. If your truck is pulling to one side or your tires are wearing unevenly, have your wheels aligned by a professional. Wheel alignment will ensure that your tires are properly aligned with the road, preventing premature wear and improving handling.

By following these simple maintenance tips, you can keep your 2019 RAM 1500 Classic's tires in good condition and enjoy a safe and comfortable ride for years to come.
