Tire sidewall height

Question

When a tire is labeled "185/70/14'" that means it is 185 mm wide, the sidewall height (from the rim to the road) is 70% of its width, and the wheel had a diameter od 14 in. What is the tires sidewall height?

Answer 1

Hi Kim,

 

The sidewall height is 70% of its width, and the width is 185 mm.

 

So the sidewall height is 70% of 185 mm:

 

0.7 * 185mm = 129.5mm

 

 

Hope this helps!
