160/60ZR17
WidthThe first number — 160 here — is the tire's width in millimeters, measured straight across the tread from one sidewall to the other while it's mounted and aired up.
Aspect ratioThe second number is the sidewall height, written as a percentage of the width. A 60 means the sidewall stands 60% as tall as the tire is wide — the lower the number, the shorter and stiffer the sidewall.
Rim sizeThe last number is the wheel diameter the tire's built for, in inches. This one's non-negotiable — it has to match your rim exactly.
What about the ZR? R means radial construction, standard on nearly every modern street tire. The letter in front of it (Z here, sometimes H or V) is a speed rating. Neither is needed for the finder above — but now you'll know what you're looking at on the sidewall.
Look for the size molded right into the sidewall of your current tire, usually just above the rim.
