What 245/35 R21 means
- 245: the tyre is 245 mm wide, measured across the sidewalls.
- 35: the sidewall height is 35% of the width, so 245 × 35% = 85.8 mm.
- R: radial construction. A ZR in the same place is the same size with a speed marking for over 240 km/h.
- 21: it fits a 21-inch wheel. Overall diameter is 21 × 25.4 mm plus two sidewalls: 704.9 mm.
The load index and speed rating follow the size on the sidewall (for example 91V). Replace like for like or higher, as your handbook states.

What to look for in a 245/35 R21 tyre
- Low profile, less cushion. An 85.8 mm sidewall on a 21-inch wheel leaves little to absorb a pothole or a kerb, so check for bulges and rim damage after a hard hit, and have the wheel alignment checked if the steering pulls or the new tyres wear on one edge.
- Electric cars. This size is common on EVs, which are heavier than a petrol car of the same size. Keep at least the original load index (some EVs use HL or XL tyres), and check the tread more often: the extra weight and instant torque can wear tyres faster.
- Winter or all-season. If you want winter or all-season tyres in 245/35 R21, the live list shows what is made in this size today; not every pattern is made in every size.

Frequently asked questions
Is 245/35 R21 the same as 245/35 ZR21?
Yes, the dimensions are the same. The Z marks a tyre rated for over 240 km/h (149 mph); the exact rating is the letter after the load index, such as W or Y. Fit at least the speed rating your handbook gives for the car.
Can I fit 245/40 R20 instead of 245/35 R21?
Only if 245/40 R20 is listed for your car. On paper it is 704 mm tall against 704.9 mm for 245/35 R21, a 0.1% difference, so the speedometer would barely change. It also needs a 20-inch wheel instead of a 21-inch one. Wheel width, arch clearance, load index and speed rating must suit the car too, so check the handbook or the door placard, and fit one size across an axle.
How tall is a 245/35 R21 tyre?
About 704.9 mm (27.8 inches) across when new and unloaded: the 21-inch rim (533.4 mm) plus two sidewalls of 85.8 mm, which is 35% of the 245 mm width. Real tyres differ by a few millimetres between brands and patterns.
Which cars use 245/35 R21 tyres?
Fitment listings give 245/35 R21 for the BMW 5 Series, MINI Countryman, Tesla Model S and Volvo V90 / S90. One model can use several sizes depending on its wheels, so check the sidewall of your own tyres before you book.
