## What does 91V mean on tires?

Speed rating Speed rating corresponds to the maximum speed that a tire can sustain when it is carrying the recommended load capacity. The rating system uses letters from A to Z. Here, you can see that a tire with a 91V mark can them run at a maximum speed of 149 mph while carrying 615 kilograms or 1,356 pounds load.

**Which is better V or H speed rating?**

H-rated tires are rated for a maximum speed of 130 mph. The V rating is the next rating faster, and V-rated tires are good to 149 mph. Both H- and V-rated tires are considered to be performance-touring tires.

### Does speed rating matter on tires?

The speed rating tells you the speed the tire can safely maintain over time. A higher speed rating usually means you will have better control and handling at higher speeds – and that the tire can take the extra heat. As a general rule, tires with higher speed ratings also handle better at slower speeds.

**What is the T rating on a tire?**

118 mph

T speed rating A T speed rating indicates the tire is approved for speeds up to 118 mph (190 km/h) under optimal conditions. T ratings are most associated with standard touring tires, and everyday passenger vehicles.

#### Can I use lower speed-rated tires?

It is not recommended to choose lower speed-rated tires just because they’re less expensive, and you should be extra careful to replace any bad tires with the same rating as the rest of your tires.

**Can I use 215 65r16 instead of 225 60R16?**

**What does 91V stand for on a tire?**

The markings 91V are the load index and the speed rating, or the service description. The load index (91) is the assigned numerical value for the tire size to compare relative load carrying capabilities. The table below shows the load indexes of the tires that are commonly used in passenger cars and light trucks.

### What’s the maximum speed of a 91V tire?

Speed rating corresponds to the maximum speed that a tire can sustain when it is carrying the recommended load capacity. The rating system uses letters from A to Z. Here, you can see that a tire with a 91V mark can them run at a maximum speed of 149 mph while carrying 615 kilograms or 1,356 pounds load.

**What is the weight of a 91 tire?**

The load index (91) is the assigned numerical value for the tire size to compare relative load carrying capabilities. The table below shows the load indexes of the tires that are commonly used in passenger cars and light trucks. Using this table, we can compute that a vehicle with a 91 load index can carry 615 kilograms or 1,356 pounds.

#### What’s the average speed of a V rated tire?
