What 145/80 R12 means
- 145: the tyre is 145 mm wide, measured across the sidewalls.
- 80: the sidewall height is 80% of the width, so 145 × 80% = 116 mm.
- R: radial construction. A ZR in the same place is the same size with a speed marking for over 240 km/h.
- 12: it fits a 12-inch wheel. Overall diameter is 12 × 25.4 mm plus two sidewalls: 536.8 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 145/80 R12 the same as 145/80 ZR12?
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 155/70 R13 instead of 145/80 R12?
Only if 155/70 R13 is listed for your car. On paper it is 547.2 mm tall against 536.8 mm for 145/80 R12, a 1.9% difference, enough to move the speedometer reading slightly. It also needs a 13-inch wheel instead of a 12-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 145/80 R12 tyre?
About 536.8 mm (21.1 inches) across when new and unloaded: the 12-inch rim (304.8 mm) plus two sidewalls of 116 mm, which is 80% of the 145 mm width. Real tyres differ by a few millimetres between brands and patterns.
