McLaren tire sizes

We cover 2 McLaren models across 4 factory fitments, spanning model years 2016 to 2023. The size that turns up most often on a McLaren is 225/35R19, followed by 285/35R20 and 245/35R19. Wheel diameters run from 19 to 20 inches, so the trim and wheel package matter as much as the model year.

McLaren 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.

McLaren Automotive began selling road cars in the United States in 2011 with the MP4-12C and has built its range around a carbon fiber tub and a mid-mounted twin-turbo V8 ever since. US volume is around a thousand cars a year, and the United States is its largest market. The cars are lighter than their rivals and carry no all-wheel drive, which changes the tire math: less weight but all the drive and most of the grip going through the rear pair.

Tires on a McLaren

McLaren does not use a single widely published sidewall letter the way BMW uses a star or Porsche uses N codes, and the practical rule is to replace with the exact fitment McLaren specified for the car, matching size, load index, speed rating and pattern rather than hunting for a code. Every model is heavily staggered: the 570S runs 225/35R19 front and 285/35R20 rear, and the 720S 245/35R19 front and 305/30R20 rear, with the rear wheel a full inch larger in diameter than the front. That combination of mixed diameters and mixed widths means there is no rotation of any kind and no possibility of a single spare that fits both ends.

The 225/35R19 front on a 570S is narrow by supercar standards, which is deliberate, because the car is light and McLaren wanted steering feel rather than maximum front grip. All original fitments are summer tires; the compound goes hard below roughly 40 degrees Fahrenheit and cold-tire grip is the most common surprise for new owners. Pirelli and Michelin hold most of the fitments, and in several sizes only one or two patterns are offered, so the choice is usually availability rather than preference.

The models that matter

The 2016 to 2021 570S runs 225/35R19 front and 285/35R20 rear. The 2018 to 2023 720S goes wider at both ends, 245/35R19 front and 305/30R20 rear. Other models from the same era, including the 650S and the GT, use fitments in the same 225 to 305 millimeter range on 19 inch front and 20 inch rear wheels, so the same ordering logic applies.

What owners find out later

Because front and rear wheels differ in diameter as well as width, a McLaren needs two completely different tires and cannot carry a useful spare, and none of these cars has one. The carbon tub means the car is light enough that tires often age out before they wear out, so the date code on the sidewall matters more than the tread depth on a low-mileage car. Tire pressure sensors are matched to the car and a second set of wheels needs its own coded in.
