What is the diameter of a 275/60 R17 tire?

Accepted Answer

A 275/60 R17 tire has a nominal overall diameter of 762 mm (30.0 inches), a sidewall height of 165 mm and a rolling circumference of 2393 mm. These are nominal figures calculated from the size marking; actual dimensions vary by manufacturer, load and wear.

Question 2

What do the numbers in 275/60 R17 mean?

Accepted Answer

275 is the nominal section width in millimetres. 60 is the sidewall height expressed as a percentage of that width, giving a 165 mm sidewall. R denotes radial construction, and 17 is the wheel bead-seat diameter in inches — which is not the overall tire diameter.
