What size tires are on a 2008 Dodge RAM 2500?
The factory tire sizes for a 2008 Ram 2500 vary by wheel and trim, but the most common stock options were LT245/75R16 on 16-inch wheels or LT265/70R17 on 17-inch wheels.
The 2008 Ram 2500 offered multiple wheel-and-tire configurations depending on cab/bed setup and option packages. To confirm the exact size for a specific truck, check the tire information placard on the driver’s door jamb or consult the owner’s manual or build sheet. If you’re measuring current tires, the sidewall markings will indicate the exact size (for example, LT245/75R16 or LT265/70R17).
How tire sizes vary by wheel and trim
The 2008 Ram 2500 was offered with different wheel sizes and corresponding tire dimensions. Here are the typical factory sizes you might encounter, along with notes about when each applies.
- 16-inch wheel packages: commonly equipped with LT245/75R16 tires (sometimes P245/75R16 on non-LT setups).
- 17-inch wheel packages: commonly equipped with LT265/70R17 tires (these are among the most common large-truck sizes for that generation).
- Some special or optional packages may have 18-inch wheels with larger tires, but these were less common on the 2008 model year and often depend on dealer-installed swaps or later model years.
In short, the best way to know for sure is to read the label on the door jamb and verify on the sidewall of the tires currently on the vehicle, or refer to the build sheet for the specific truck you own or are considering.
Verifying your exact tire size
To ensure accuracy, use one of these verification methods:
- Check the driver's door jamb sticker for the "Tire Size" entry, which lists the standard and optional sizes.
- Consult the owner's manual or the original window sticker (Monroney) if you have access to a used truck's paperwork.
- Inspect the tire sidewalls themselves: the size is printed as a sequence like LT245/75R16 or LT265/70R17, along with load and speed ratings.
For anyone planning to replace tires or adjust ride height, remember to match load index and speed rating to your vehicle's gross vehicle weight rating and intended use, and take into account recommended tire pressure for the specific tire size.
