Ram 1500 Tire Sizes, Pressure and Bolt Pattern

Each row links to the full specification for that generation, including trim-by-trim breakdowns and the part numbers. Where engines within a generation differ, that page separates them.

The tire sizes on a Ram 1500 is set by its generation, not its model year, so each generation has one page carrying the complete figures, part numbers and fitment notes for every year it covers.

What size tires does a Ram 1500 take?

It varies by trim and wheel size, 5 factory fitments exist, from 275/65R18 up. Check the placard on the driver's door jamb for the size your specific vehicle left the factory with.

What is the bolt pattern on a Ram 1500?

6x139.7 (6x5.5). That is the figure you need when shopping for aftermarket wheels; centre bore and offset still have to match separately.

What should the tire pressure be on a Ram 1500?

36 PSI front and rear, measured cold. The number moulded into the tire sidewall is the tire's maximum, not the vehicle's recommendation. Do not inflate to it.

What is the lug nut torque for a Ram 1500?

130 lb-ft, tightened in a star pattern with a torque wrench. Impact guns routinely overshoot this by 100 lb-ft or more, which warps rotors and stretches studs.

Does the Ram 1500 come with a spare tire?

Full-size spare under the bed (not on TRX with 35s. Its spare is smaller than the road tires).
