BEFORE YOU COMPARE
Tyre load index and speed rating explained
The number after the tyre size identifies its load capacity; the following letter identifies its speed category. Match both to your vehicle’s approved specification.
For example, 205/55 R16 91V contains three different checks: the size, load index 91 and speed symbol V. Matching only “205/55 R16” leaves two requirements unchecked.
Common load-index examples
| Index | Load |
|---|---|
| 91 | 615 kg |
| 94 | 670 kg |
| 95 | 690 kg |
| 98 | 750 kg |
| 100 | 800 kg |
A tyre’s load capacity does not increase the vehicle’s permitted axle weight. Do not calculate a new vehicle payload by multiplying these figures by four.
Common speed symbols
| Symbol | Category maximum |
|---|---|
| T | 190 km/h |
| H | 210 km/h |
| V | 240 km/h |
| W | 270 km/h |
| Y | 300 km/h |
These are selected examples, not the complete chart. Manufacturer guidance covers exceptions and specialist high-speed markings. Michelin’s load and speed reference ↗.
What about XL and HL?
XL denotes extra-load construction. HL identifies high-load tyres; it is not interchangeable with an ordinary tyre simply because the dimensions match. Preserve the required construction and markings when choosing a replacement. Michelin’s tyre-marking guide ↗.
Use the ratings in a comparison
Our 205/55 R16 comparison contains several rating combinations. Open each exact variant to compare its specification, label and dated offers. Use the manufacturer car references and your vehicle’s applicable manual to establish the requirements first. The BMW M5 reference illustrates why HL and separate axle sizes must remain explicit.
