In a tire with metric sizing, on an example of 120/70ZR17:
120=tire width in millimeters
70=aspect ratio
Z=speed rating
R=construction type
17=rim diameter in inches
In a tire with alpha numeric sizing, on an example of MT90H16:
M=motorcycle use
T=tire width code
90=aspect ratio
H=speed rating
16=rim diameter
To change an actual tire you need a tire machine to get it off the rim and the new one on. -If you mean the change the WHEEL and tire on a car, then you just need a jack and a tire wrench.
There is no date. Expiration depends on wear. However, you may find the production date on a tire. Look for the DOT numbers on what would be the inside of the tire. Example, DOT 02112 would be the 21st week of 2012 that tire was produced.
If you mean the Flat tire indicator button, it's next to the parking brake.
It shows the size of the tire. Converted to EU Standarts is 205/75 - 15
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.
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.
That is NOT a tire size. -The size is a much longer series of numbers and letters.
One number is the overall tire height, one is tire width and the other is the inside diameter.
The numbers on a bike tire indicate the tire's size and recommended air pressure. The first number is the tire's width in millimeters, and the second number is the diameter of the wheel in inches. The higher the tire pressure, the less rolling resistance and better performance, but it may also affect comfort and traction.
that you have low tire pressure. get more air in your tires and fill it to the numbers located somewhere near the driver's door
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.
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.
There are a series of numbers printed on the sidewall of the tire, just above the bead area. They will not be as uniformed or professional looking as the tire size number or printed brand of the tire. One side of the tire will have these additional numbers and the other side won't. The side with the most numbers", will tell you the manufacture date. The last 4 numbers are the date recorded as week and year. For instance if it lists 1608, then the tire was made the 16th week of 2008.
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.
for instance 205/55/20 205 is 205 mm across the tire (width) 55 is 55 mm the profile 55 is a low profile tire (height of wall) And 20 is diameter or the rim ( size of the rim)
