Detailed tire and wheel breakdown for the 2023 Rolls-Royce Ghost
Tire geometry â 255/40R21
The 255/40R21 fitted to the 2023 Rolls-Royce Ghost has a section width of 255mm and an aspect ratio of 40%, mounted on a 21-inch rim. That gives a sidewall height of 102.0mm (4.02") and an overall outside diameter of 737.4mm (29.03"). At highway speed this tire completes roughly 432 revolutions per kilometre, which is what your speedometer and odometer are calibrated against.
Plus-sizing window
If you want to upsize wheels on the 2023 Rolls-Royce Ghost while keeping the speedometer accurate, target a 265/34R22 (plus-one). For a softer ride or winter setup, a 245/47R20 (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 2023 Rolls-Royce Ghost uses a 5x120 bolt pattern with a 66.6mm hub bore. Safe rim width range for the OEM tire is 8.0J â 9.0J, and offsets in the ET20 â ET30 window will clear suspension and fender without rubbing on most setups.
Staggered setup notes
The 2023 Rolls-Royce Ghost ships staggered: 255/40R21 up front and 285/35R21 on the rear. That is a 285mm vs 255mm 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 2023 Rolls-Royce Ghost 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%.
