Detailed tire and wheel breakdown for the 2018 Audi R8
Tire geometry â 245/30R20
The 245/30R20 fitted to the 2018 Audi R8 has a section width of 245mm and an aspect ratio of 30%, mounted on a 20-inch rim. That gives a sidewall height of 73.5mm (2.89") and an overall outside diameter of 655.0mm (25.79"). At highway speed this tire completes roughly 486 revolutions per kilometre, which is what your speedometer and odometer are calibrated against.
Plus-sizing window
If you want to upsize wheels on the 2018 Audi R8 while keeping the speedometer accurate, target a 255/24R21 (plus-one). For a softer ride or winter setup, a 235/37R19 (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 2018 Audi R8 uses a 5x112 bolt pattern with a 66.5mm hub bore. Safe rim width range for the OEM tire is 8.0J â 9.0J, and offsets in the ET37 â ET47 window will clear suspension and fender without rubbing on most setups.
Staggered setup notes
The 2018 Audi R8 ships staggered: 245/30R20 up front and 305/30R20 on the rear. That is a 305mm vs 245mm width difference â do not rotate front-to-rear, and replace tires in axle pairs to keep ABS and traction control balanced.
Tire pressure guidance
Manufacturer-recommended cold tire pressure for the 2018 Audi R8 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%.
