Wheel fitment specs
The 2010 Audi Q7 uses a 5x130 bolt pattern with a 71.6mm hub bore. Safe rim width range for the OEM tire is 7.5J â 8.5J, and offsets in the ET51 â ET61 window will clear suspension and fender without rubbing on most setups.
Tire pressure guidance
Manufacturer-recommended cold tire pressure for the 2010 Audi Q7 is printed on the driver-side door jamb sticker â always defer to that value, not to the maximum pressure printed on the tire sidewall. Check pressure monthly and before long trips; under-inflation by 20% can reduce tread life by 25%.
