What 285/50 R18 means
- 285: the tyre is 285 mm wide, measured across the sidewalls.
- 50: the sidewall height is 50% of the width, so 285 × 50% = 142.5 mm.
- R: radial construction. A ZR in the same place is the same size with a speed marking for over 240 km/h.
- 18: it fits an 18-inch wheel. Overall diameter is 18 × 25.4 mm plus two sidewalls: 742.2 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.

Frequently asked questions
Is 285/50 R18 the same as 285/50 ZR18?
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 285/45 R19 instead of 285/50 R18?
Only if 285/45 R19 is listed for your car. On paper it is 739.1 mm tall against 742.2 mm for 285/50 R18, a 0.4% difference, so the speedometer would barely change. It also needs a 19-inch wheel instead of an 18-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 285/50 R18 tyre?
About 742.2 mm (29.2 inches) across when new and unloaded: the 18-inch rim (457.2 mm) plus two sidewalls of 142.5 mm, which is 50% of the 285 mm width. Real tyres differ by a few millimetres between brands and patterns.
