What does the numbers on the side of the tires mean? (In order)?

Answer 1

Like use P275/50r17
P = Passenger or LT = Light Truck
275 is width in millimeters
50 is aspect ratio of width. So 50 would be 137.5 mm on this size.
r = radial
17 is rim diameter in inches

Answer 2

P = passenger
LT = Light truck
This would be type.
Next are two numbers, such as 215/65
First is the width of the tire in millimeters. In this case, 215 mm.
Next is the aspect ratio, or in this case 65% of the width.
Next is construction, usually "R" for steel belted radial, but there are still bias ply tires out there, "B"
Next is the wheel diameter size, this is in inches. 13, 15, whatever it is.
Next is the load index, the weight the tire is rated for when properly inflated. You will also find this on the side of the tire in another spot in both pounds and kilograms.
Last is the speed rating, with H being rated for 130 miles per hour.
You may also find "DOT" at the end, which means it's DOT compliant, and there will be a 12 digit serial number somewhere if it is. (this is mostly on truck tires)

Answer 3

Standard tires:
xxx - yy - R zz

X= Tread width measured in millimeters (135 to 345 is typical)
Y= Percentage of tread width contained in the sidewall (35-75 not more than 100)
Z= Rim size measured in inches (12-24)

so a 205-50-16 tire would be 205mm wide with a 102.5mm sidewall and 16 hole for the shiny factory rim

If you have extra letters its a speed rating, you can look those up.

Some motorcycle tires have tread width in inches 3.50x19inch rim
Mud truck tires tend to list the overall height of the tires 33x15inch rim
And there are metric rims out there that are hard to find tires for.

Answer 4

size of the rim, outer diameter, thickness and type of thread weave (Radial or cross-ply).
Need the number to give you in sequence.

1. 205 Width of the tire in millimeters.
2. 55 Aspect ratio - This sidewall's height is roughly
55% of the tire's width.
3. R For radial construction
4. 16 Nominal rim diameter code of the wheel on which
the tire fits.
5. 88 Load index is a numerical code associated with
the maximum load a tire can carry under certain
service conditions.
6. V Speed symbol - This tire can carry a specified
load under specified service conditions at
speeds up to 149 mph.
7. 88V Service description, a combination of the Load
Index and Speed Symbol.

Service Description
The service description contains a two-digit number (load index) and a letter (speed rating).
In this example (left) the service description has a load index of 82 and a speed

Answer 5

Bob-

This will tell you everything you need to know.

Ex. 225/50 R16

The first number indicates this tire is 225 millimeters across from the widest point of its outer sidewall to the widest point of its inner sidewall when mounted and measured on a specified width wheel.
The second number indicates that this tire size's sidewall height (from rim to tread) is 50% of its section width.
The third is the rim size in inches (the "R" means and radial ply tire construction).

Answer 6

if a tire says its a 235/65/15 it means the tire width is 235 mm wide and the 65 means 65% of 235 is the sidewall and 15 means it's a 15 inch tire

Answer 7

there will be some numbers like r14-35-165 that is the size of the tire the other number that says something like 40 psi is the air pressure that the tire should be at.3

Answer 8

profile, width, rim size

profile is the height from the ground to the top of the tire this measurement is in mm

width is the width of the tire also in mm

rim size is the size of the rim

example: 195=height 75=width r15=rim size

Answer 9

many right awnsers here. but eveone only covered metric tires.
if you have a standard size tire (found on many trucks).
for example 31x10.5x15
the tire would be 31 inches in diameter. 10.5 inches wide and fit on a 15 inch wheel

Answer 10

How wide are the tires (in mm)?

How tall are the tires (aspect ratio)?

How big are your wheels (diameter in inches)?
