∙ 9y agoThe numbers represent the aspect ratio. lets use 235/60 15 as an example. the 235 means the tire is 235mm wide. the 60 means the tire is 60 percent as wide as it is tall and the 15 is the size wheel the tire will fit. If you have 235/75 15 the tire is still 235 mm wide but the sidewall is taller at 75 % of 235.
For example, 225/60R14
The tread face is 225 Millimeters wide,
The / symbol is just to separate the numbers
The tire side wall is 60% as high as the tread face is wide.
R means the tire is of radial construction (D) means Bias ply
14 means the tire is to be mounted on a 14 inch diameter rim
Older system (this system was replaced in the 1970's)There is an older system for example: H78-14The H is the tire weight rating
The 78 is the height and tread face size (I have no Idea what the basis is)
14 is the wheel size

∙ 13y agoI will use my tire size H215/60R14
- H is the Speed rating but can be LT for light truck or ST for special trailer use only
- 215 is 215 mm tread wide tread
- / is just a visual divider
- 60 means the side wall (bead to tread face) is 60% as tall as the tread is wide or 129 MM tall
- R means this is a radial tire
- 14 is the wheel diameter 14 inches in this case, There have been metric wheel sizes 390 MM for instance.

∙ 11y ago- My mini 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 the load rating
- H is the speed rating.
The aspect ratio is the percentage of tread width that the sidewall is tall.
so in this example the side wall is 65% of 215 mm or about 139.75 mm tall

How do you get a razor blade in your tire?
If you mean that you found one inside your tire and are wondering how it got there, it was probably dropped inside and forgotten by the last technician that had your tire dismounted. It was probably used to cut a plug to repair a puncture. If you mean that you want to know how to put one inside, then you have to dismount the tire from the rim (or at least deflate the tire and push a portion of the tire bead off of the rim) and insert the blade. Not sure why anyone would want to, but to each, his own. If you mean that there was a razor blade embedded in the rubber, either you ran over it, or someone else stuck it there to sabotage your tire, or it may have been embedded during the tire's manufacture. If you suspect the latter (manufacture defect) you should contact the tire dealer that sold it to you and demand replacement.
