How can you tell the width of a tire?

Tire numbers explained

- My van tires are - - P215/65R15 95H.

- That P means it's a passenger vehicle tire,

- 215 is tread width in millimeters,

- 65 is the aspect ratio, it's a wide oval. ( 75 means it's rounder in cross section)

- R means it's a Radial

- 15 means it fits a 15" rim.

- 95 -is it's load range, and in the ISO/Metric Standards list '95' means each tire can support 1500 pounds weight.

- H - The final letter is it's 'speed rating' , and again in the ISO/metric system, 'H' means it's rated at speeds up to 130 mph. I hope this helps to explain it all and for you to choose good tires, please remember -always identical tires on both sides rear, and identical tires on both sides front. This will mean more equal braking, and better steering.
