how do you read the numbers on the side of a tire?

Answer 1

ok instead of these smartass comments (though above is good though wasn't there when i first answered the question)

eg 175 75R14

175= width of the tyre at the tread in millimeters
75= aspect ratio of the sidewall (in this case 75% of 175mm = 131.25mm) high
R= means that the tyre is a radial tyre (almost all are now)
14= means that it goes on a 14 inch tyre

the websites below should help a little if you wish to try different size tyres

Answer 2

Tire Type defines the proper use of the tire. For example, the “P” on the tire shown here means that this is a passenger car tire. If the tire had an “LT” designation, the tire would be for a light truck.

Tire Width is the width of the tire measured in millimeters from sidewall to sidewall. This tire width is 215 millimeters.

Aspect Ratio is the ratio of the height of the tire's cross-section to its width. On our example, 65 means that the height is equal to 65% of the tire's width.

Construction tells you how the layers of the tire were put together. The “R” stands for Radial which means the layers run radially across the tire. A “B” stands for bias construction which means that the layers run diagonally.

Wheel Diameter is the width of the wheel from one end to the other. The diameter of this wheel is 15 inches.

Load Index indicates the maximum load in pounds that the tire can support when properly inflated. You'll also find the maximum load elsewhere on the tire sidewall, both in pounds and kilograms.

Speed Rating tells you the maximum service speed for a tire. “H” means that the tire has a maximum service speed of 130 mph. This rating relates only to tire speed capability and is NOT a recommendation to exceed legally posted speed limits. Speed Rating Chart

DOT means that the tire complies with all applicable safety standards established by the U.S. Department of Transportation (DOT). Next to this is a tire identification or serial number — a combination of numbers and letters up to 12 digits.

UTQG stands for Uniform Tire Quality Grading, a rating system developed by DOT. For more information on UTQG, continue here.

Answer 3

depends on if it is a metric tire or standard. If it is metric it would read like 215/65/15, the first number is the width 215,the second is the height 65, and the third is the rim size. A standard would read 33-12.50-15. 33 is the height, 12.50 is the width, and 15 is the rim size. Metric is measured in millimeters and standard is measured in inches

Answer 4

...

1 = one
2 = two
3 = three
4 = four
5 = five
6 = six
7 = seven
8 = eight
9 = nine
0 = zero

But you know how to read the letters right?

K but seriously?

Those numbers mean the thread type & the with of the wheel

There will also be other numbers describing what model & recommend PSI

If you want to order a tire... You look for the one that starts with a letter then a few numbers a letter again then a few numbers

Answer 5

Example: P235/70R16AS
P=Passenger, 235=Tire Width in MM, 70=Profile of tire(Ratio of height to width)((80 series would be a taller tire than a 70 series)), R16= rim(wheel) Height, and finally AS= all season.

Answer 6

P205-75R15
Passenger 205 is the high from top to bottom 75 is width Radial 15 inch wheel

LT265-85R15 is Light Truck the rest is the same.

Answer 7

Easiest thing is to check out this page:

For example, my Camry Solara has a tire size P215/55-17.

Answer 8

bend over slant your head toward the tire and look at the numbers. they are very small

Answer 9

It's easy, stop the car and look, they are printed in english.
