Chevrolet Silverado 1500 tire sizes: common questions
What size tires does a Chevrolet Silverado 1500 take?
- It varies by trim and wheel size, 5 factory fitments exist, from 255/70R17 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 Chevrolet Silverado 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 Chevrolet Silverado 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 Chevrolet Silverado 1500?
- 140 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 Chevrolet Silverado 1500 come with a spare tire?
- Full-size spare winched under the bed; ZR2 runs 33-in mud-terrains (275/70R18).
