Rolls-Royce tire sizes

We cover 3 Rolls-Royce models across 4 factory fitments, spanning model years 2010 to 2024. The size that turns up most often on a Rolls-Royce is 255/50R22, followed by 255/50R20 and 285/45R20. Wheel diameters run from 20 to 22 inches, so the trim and wheel package matter as much as the model year.

Rolls-Royce does not stamp an approval code on tires the way Porsche and BMW do, so any tire in the right size that meets the load index and speed rating on the door placard is a legitimate replacement. Pick on wet braking, tread life and price instead.

Pick your model below to see the size for every year and trim, what it costs from budget to premium, and which tires are worth buying in that size. If you already know your size, search by size instead, and if you are not sure where to find it, our guide on reading a tire size shows exactly where the placard sits.

Rolls-Royce Motor Cars has been owned by BMW since 2003 and builds the Phantom, Ghost, Cullinan and Spectre at Goodwood in England. Global production is in the low thousands a year and the United States is its largest market. The cars are very large and very heavy, a Cullinan weighing close to 6,000 pounds, and the design brief is silence above everything.

Both facts drive the tire specification, which is why Rolls-Royce fitments look unusual next to other cars on 22 inch wheels.

Tires on a Rolls-Royce

There is no single widely published Rolls-Royce sidewall letter in the way BMW uses a star, so the rule here is to replace with exactly what the car came with, matching size, load index, speed rating and any self-supporting or run-flat designation. What is distinctive is the shape of the fitment: the Phantom and Cullinan both run 255/50R22, which is a 22 inch wheel with a genuinely tall 50-series sidewall, where most vehicles on 22s are running 40 or 45 series. That is deliberate, because the sidewall is doing ride and noise work that the suspension cannot do alone, and it is why fitting a lower-profile tire to the same wheel ruins the car's defining quality.

The Ghost is staggered at 255/50R20 front and 285/45R20 rear. Rolls-Royce specifies self-supporting tires on several models so the car can keep moving after a puncture, and the approved fitments are typically model-specific constructions with noise-reducing measures inside. Choice inside these sizes is narrow, sometimes a single pattern, so availability rather than preference decides.

Tires also age out before they wear out on most of these cars, given the mileage they cover.

The models that matter

The Cullinan SUV is the volume model in the US and the Phantom the flagship, and both run 255/50R22 at the front. The 2010 to 2020 Ghost is staggered at 255/50R20 front and 285/45R20 rear, and the current Ghost and Spectre use similar large-diameter, tall-sidewall fitments. Across the range the pattern is the same: very large wheels with more sidewall than the styling suggests.

What owners find out later

A 255/50R22 has around five inches of sidewall, which is more than most sports sedans have on 19 inch wheels, and that height is a functional part of how the car rides rather than a styling choice. Because the cars cover low annual mileage, the date code on the sidewall is usually what ends a set rather than the wear bars, and a Rolls with full tread can still need tires. None of these cars carries a conventional spare.

Wheel balancing on 22 inch Rolls-Royce wheels normally needs a road-force machine, because a residual vibration that would be invisible in another car is audible in this one.
