Bentley tire sizes

We cover 3 Bentley models across 7 factory fitments, spanning model years 2012 to 2024. The size that turns up most often on a Bentley is 275/35R21, followed by 315/30R21 and 285/45R21. Wheel diameters run from 20 to 22 inches, so the trim and wheel package matter as much as the model year.

Bentley 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.

Bentley builds large, heavy luxury cars in Crewe and has been part of Volkswagen Group since 1998. The range is the Bentayga SUV, the Continental GT coupe and convertible, and the Flying Spur sedan, with US volume in the low thousands a year and the Americas as its biggest region. The cars weigh roughly 5,000 to 5,700 pounds and carry W12 or V8 power, which is the fact that matters most for tires.

Bentley is priced above Porsche and below Rolls-Royce.

Tires on a Bentley

There is no single widely published Bentley sidewall letter in the way BMW has a star or Porsche has N codes, so the safe rule on a Bentley is to copy the exact original specification, including load index, speed rating and any run-flat designation, rather than to hunt for a code. What defines Bentley tires is weight combined with speed: a Continental GT can exceed 200 mph while weighing more than a full-size pickup, so the fitments are high load index tires in very large diameters, and almost all of them are staggered. The Continental GT and Flying Spur run 275/35R21 front and 315/30R21 rear, the 2012 to 2018 Continental ran 275/40R20 all round, and the Bentayga runs 285/45R21 or 285/40R22.

Nothing rotates, rears wear roughly twice as fast as fronts, and a pair of rears at this size is a four-figure purchase. Bentley specifies summer tires as standard in the US, so most owners in cold states buy a separate winter wheel and tire package, usually one diameter smaller. Pirelli and Michelin dominate the original fitments, and choice inside each size is narrow enough that availability rather than preference often decides the replacement.

The models that matter

The Bentayga is the volume model and takes 285/45R21 or 285/40R22. The Continental GT and Flying Spur share the 275/35R21 front and 315/30R21 rear package on current cars, while 2012 to 2018 Continentals ran 275/40R20. All three are staggered on current 21 inch wheels, so ordering four of the same size is always wrong.

What owners find out later

A 315/30R21 rear has under four inches of sidewall under a car weighing more than 5,000 pounds, which is why curbed and cracked rims are common and why Bentley wheels are usually repaired rather than replaced. None of the current cars carries a full-size spare. The Bentayga's 22 inch wheels are heavy enough that road-force balancing rather than static balancing is normally needed to get a smooth ride at highway speed.

Because the cars are V-rated or higher and very heavy, a tire with the right section width but a lower load index is not a safe substitute even when it physically fits.
