There is NO width number 10. -This may help you understand your tire numbers - -
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.

That is the tire profile or section width. The number is a metric figure standing for the width of the tire in millimeters.
It's the first number of the tire designation stamped on the side.
Look on the side of the tire and you will see a set of number such as 195/50 17R. The first number, in this case 195, is the tread width in millimeters.
If it's the number at the start of the tire ID ( eg 175/70/R/13 ) then it's the width in millimetres.
You must know the answer is NO. Not necessarily true, we're talking about width I assume, the section width of the tire 10" in this case is measured at the widest part of the tire. The bead, the part of the tire that sits on the wheel, is significantly narrower. Just as an example P245/55R20, which is a 10" wide tire lists the apporved rim width as 7.0"-9.0", so depending on the exact size it is very possible that your 10" wide tire could go on a 7" wide rim.
The width, by 10 mm
the first 3. 235/xx Rxx
That number is the width of your tire in millimeter units. In inch units it is 10.43 inches
It usually can
The width of the contact patch of the tire on the road.
No number specifically indicates the height. You can however figure the height with a little math. As in 245/70-15 the 245 is the width of the tire in millimeters. The 70 is the aspect ratio which means the tire's height is 70% of the tires width. So on this example the height of the tire is 171.5 millimeters.
10 cm of tread width is thee difference
