What size tires are on a Ram 1500 5.7 Hemi?
The Ram 1500 with the 5.7 Hemi does not have a single universal tire size. Factory sizing varies by year, trim level, and wheel package. To know the exact size for a specific truck, check the door jamb placard, the owner's manual, or the tire sidewall. If you share the exact year and trim, I can provide the precise factory size for that configuration.
Determining your exact tire size
Factory tire sizes vary by configuration, so use these steps to confirm the correct size for your Ram 1500:
- Check the driver’s door jamb placard for the tire size and load rating.
- Look at the sidewall of one of your tires; the size is printed in a format such as P265/70R17, indicating width, aspect ratio, construction, and wheel diameter.
- Consult the owner's manual or Ram's official specifications for your year/trim if you don’t have the placard handy.
- If you know your exact year and trim, use reputable online resources (Ram's site, dealership catalogs, or Tire Rack) to confirm the factory size.
Using these checks will ensure you replace tires with the correct size and load rating for safe operation and optimal performance.
Common wheel sizes used with the 5.7 Hemi
Ram has offered 17-, 18-, 20-, and 22-inch wheels on 1500s across different years and trims. The corresponding tire widths and aspect ratios change with each wheel size and package, so always verify the exact size printed on the truck you own or are considering buying.
In short, there is no single tire size for all Ram 1500 models with the 5.7 Hemi. Identify the exact size from the door placard, tire sidewall, or owner's manual, especially if you are shopping for replacements or upgrades. If you provide year and trim, I can give the precise factory tire size for that configuration.

How big of a tire can I put on a RAM 1500?
The largest tires you can fit on a Ram 1500 without modification depend on the truck's configuration, but generally, 33-inch tires fit on most models without rubbing. Some 4WD models can fit up to 34 inches, while some trims like the Rebel can accommodate up to 34-inch tires without rubbing, and the TRX can fit up to 37-inch tires. For larger sizes beyond these, you may need to consider a lift kit, leveling kit, or aftermarket wheels.
Without modifications
- Standard models (2WD and 4WD): 33-inch tires typically fit without rubbing.
- Some 4WD models: May be able to fit up to 34-inch tires.
- Stock wheels: The widest tire you can typically fit is a 285.
- Aftermarket wheels with lower negative offset: Can allow for wider tires up to 305 or even 315, but this can increase the chance of rubbing the inner fender.
With modifications
- Leveling kit: A 2-inch leveling kit can allow for a 33x12.50R17, 33x12.50R18, or 33x12.50R20 tire on stock wheels.
- Lifts: A 3-inch lift kit can allow for a 35x12.5x20 tire, especially with aftermarket wheels and a negative offset rim, as shown in this YouTube video.
Specific trim levels
- TRX: The Ram 1500 TRX can fit up to 37-inch tires, though tires over 35 inches may have limitations, especially off-road, according to WheelSetGo.
- Rebel: Can accommodate up to 34-inch tires without rubbing (with air suspension) and some slim 35-inch tires without suspension modification.
Before you buy
- Check your specific vehicle: It's best to check the driver's side door jamb or the owner's manual for your exact truck model and year, as tire sizes can vary by trim and options.
- Factor in speed and odometer changes: Installing larger tires can affect your speedometer and odometer readings. You may need to calibrate them after the upgrade, notes Reddit and this YouTube video.
- Be aware of potential issues: Even if a tire fits, it could cause issues like rubbing, especially at full steering lock, particularly with aftermarket wheels that have a lower offset.
