Detailed tire and wheel breakdown for the 2014 Porsche Cayenne
Tire geometry â 295/35R21
The 295/35R21 fitted to the 2014 Porsche Cayenne has a section width of 295mm and an aspect ratio of 35%, mounted on a 21-inch rim. That gives a sidewall height of 103.3mm (4.06") and an overall outside diameter of 739.9mm (29.13"). At highway speed this tire completes roughly 430 revolutions per kilometre, which is what your speedometer and odometer are calibrated against.
Plus-sizing window
If you want to upsize wheels on the 2014 Porsche Cayenne while keeping the speedometer accurate, target a 305/30R22 (plus-one). For a softer ride or winter setup, a 285/41R20 (minus-one) keeps the overall diameter within Âą3% of stock, which is the industry tolerance for ABS and stability control to stay calibrated.
Wheel fitment specs
The 2014 Porsche Cayenne uses a 5x130 bolt pattern with a 71.6mm hub bore. Safe rim width range for the OEM tire is 9.5J â 10.5J, and offsets in the ET45 â ET55 window will clear suspension and fender without rubbing on most setups.
Tire pressure guidance
Manufacturer-recommended cold tire pressure for the 2014 Porsche Cayenne 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%.
