It depends. On a tire sized like a P235/75R15, the 235 is the tread width in millimetres. On a 33-12.50-15 the first number is the height in inches.
Width of the tread in millimeters.
On a metric sized tire it is the tread width. Example, p225/75r15. The tread is 225 mm wide.
the size of the tire, the model, when it was made
numbers mean the size of the tire,the size of the wheel they will fit on and the width of the tire.also found on all tires are a serial number
It is how big you want your tire to be its to big or to wide.
Answer The numbers on the side of tires mean the sizes and heights of the tire in question. If the numbers weren't there no one would know the tire size. More exactly... Taking 195/75R14 as an example...The first number is the measurment in milimeters of the widest part of the tread- The second number is the height of the sidewall in relation to the first number expressed as a percentage (the height of the tire is 75% of the first number) and the last number behind the R is the rim size in inches.
That is NOT a tire size. -The size is a much longer series of numbers and letters.
265 70 16 tire size will fit on 16 inch rims. The first numbers of the range indicate the tire face. The second set of numbers is the tire height. The last set of numbers indicates the rim size.
One number is the overall tire height, one is tire width and the other is the inside diameter.
The date the tire is manufactured is written on the tire sidewall. You will see DOT followed by numbers and letters. The last 4 numbers are the date of manufacture. First two numbers in that group of four, are week of manufacture and last two numbers are year. An example would be DOT 456 R9S6 0211. This would indicate the tire was manufactured the second week of 2011.
The first three numbers are the width in millimeters, the second set is the height of the tire (edge of the width to the bead) expressed as a percentage of the first number and then R__ is the rim size. For example, a 205/55R16 tire is 205mm wide, (205×.55) 112mm tall with a 16 inch wheel
The treadwear rating of a tire is a reflection of the expected lifespan of the tire. The higher the treadwear rating, the longer the tire should last. This rating is based on comparison with a "Course Monitoring Tire" (CMT)with an assigned treadwear of "100." A tire with 300 treadwear should last three times longer than the CMT. However, most manufacturers use this rating as a marketing technique. This means that many treadwear numbers are stated higher than "actual" to give an advantage over a competing tire/brand. Treadwear numbers, however, can usually be reliable when comparing different tire offerings from the same manufacturer.
