Tire Designation
The dimensions of a P-metric sized tire are described in its designation as per the following table.
Example: 205/65 R 15 94V
Designation | Explanation |
|---|---|
205 | Tire width in mm |
65 | Aspect ratio height (h)/width (w) % |
R | Construction type, see table below |
16 | Rim diameter in inches |
94 | Load index, see table below |
V | Speed rating, see table below |
Designation | Explanation |
|---|---|
R | Radial |
B | Bias-belted |
D | Diagonal (Bias) |
Code | Max Load kg | Max Load lb |
|---|---|---|
91 | 615 | 1353 |
93 | 650 | 1430 |
94 | 670 | 1474 |
95 | 690 | 1518 |
Code | Max Speed km/h | Max Speed mph |
|---|---|---|
Q | 160 | 99 |
S | 180 | 112 |
T | 190 | 118 |
H | 210 | 130 |
V | 240 | 149 |
W | 270 | 168 |
Y | 300 | 186 |
The marking of the tire in the example means:
| • | 205 - Tire width is 205 mm |
| • | 65 - Aspect Ratio is 65% (height is 65% of width) |
| • | 205 - Tire width is 205 mm |
| • | 16 - The tire is for 16 inch rim |
| • | 94 - Max load is 670 kg (1,474 lb) |
| • | V - Max speed is 240 km/h (149 mph) |
There may sometimes be an added marking showing that the tire can handle more load:
| • | RF - Reinforced |
| • | XL - Extra Load |
Winter tires have an extra marking M+S.
Week of Manufacture
The week and year of manufacture is indicated on the tire.
The 2 first digits states the production week and the 2 last digits states the year. The symbol "<" points to the year. The code 0200< means that the tire is manufactured week 02 year 2000.
Replacing Tires
When replacing wheels/tires/rims using other dimensions always use the diagnostic tool to program the new values to avoid inaccuracy for e.g. speedometer, odometer and TPMS.
Most P-metric tire sizes do not have exact corresponding alphanumeric tire sizes. Replacement tires should be of the same tire performance criteria TPC specification number including the same size, the same load range, and the same construction as those originally installed on the vehicle.
