2012–2018 Ram 1500 Tire Sizes, Pressure and Bolt Pattern

Which Ram 1500 model years does this cover?

These tire sizes specifications apply to every Ram 1500 built from 2012 through 2018 — the DS (4th generation; sold 2019–2024 as Ram 1500 Classic), full-size half-ton pickup (regular, quad, crew cab). Nothing in this specification changes between those model years. Pick your year for the engines it offered, what changed that year, and the problems recorded against it.

What size tires does a 2012–2018 Ram 1500 take?

It varies by trim and wheel size, 4 factory fitments exist, from 265/70R17 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 2012–2018 Ram 1500?

5x139.7 (5x5.5). 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 2012–2018 Ram 1500?

35 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 2012–2018 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 2012–2018 Ram 1500 come with a spare tire?

Full-size spare under the bed on most configurations (winch-down).
