The 91H and 91T refer to the tire Load bearing index and speed rating of the tire. (Load Index 91 refers to 1356 Pounds or 615 Kilograms). Typically, the load indexes of the tires used on passenger cars and light trucks range from 70 to 110. The H and T refer to the speed rating of the tire.

What is the difference between 91T and 91H tires?

The difference is the speed rating or what the tires are tested up to for speed. A T speed rated tire is tested up to 118mph while H is tested up to 130mph. A difference in this rating should not cause you issue unless you are hitting max speeds or if your vehicle is all wheel drive.

What does the T or H mean on tires?

The “T” or “H” on tires pertain to their speed ratings. A T-rated tire can withstand top speeds of up to 118 mph (190 km/h), while an H-rated tire can support up to 130 mph (210 km/h). It is important to note these markings and stay within those speed limits.

Should I get H or T rated tires?

Tires with higher speed ratings generally have better steering response and cornering grip than lower-speed rated tires, in addition to being capable of higher speeds. So if your car originally came with H-rated tires, that’s what you should replace them with.

What does 91W mean on tyres?

While a Z-speed rating still often appears in the tire size designation of these tires, such as 225/50ZR16 91W, the Z in the size signifies a maximum speed capability in excess of 149 mph, 240 km/h; the W in the service description indicates the tire’s 168 mph, 270 km/h maximum speed.

What is 91v and 91H?

It indicates the maximum speed of the tyre. V tyres have a top speed of approximately 149 mph (240 km/h) and H tyres, approximately 130 mph (210 km/h).

What does 94H mean on a tyre?

The service description is simply the speed rating and the load rating together. In our example, the service description is the last three characters: 225/45R17 94H 94 is the load rating and H is the speed rating.

What is speed rating H?

If you recall from earlier, the “H” speed rating doesn’t appear after “G” but between “U” and “V.” It represents a maximum speed of 130 mph (210 kph) and is commonly found on sports sedans and coupes.

What is load range H?

From a G to an H

Truck tires typically come in two load ratings: G and H. Load range G is a 14-ply configuration, while load range H tires have 16 plies. The heavier-rated tire will usually add between 700 pounds and 1,000 pounds more load-bearing capacity per tire (see “How Much is Too Much,” next page).

Can you mix T and H rated tires?

Just remember, never mix and match tires with different speed ratings on your vehicle. This will cause major problems with the handling of your vehicle. If tires of different speed ratings are mounted on a vehicle, the lower speed-rated tires should be placed on the front axle, regardless of which axle is driven.

Do H or V rated tires last longer?

V rated tires will most likely ride rougher, and definitely won’t last as long. The H rated tire is good for up to around 136 mph (and where would you go that fast?), and will ride better and last longer. Look on the sidewall for the tread wear number (such as 400, 500, 700, etc..). The higher the number, the better.

What does t/h mean on Michelin tires?

This letter denotes the maximum sustainable speed and is found directly after the load index. For S-speed-rated tires, it’s 112 mph; for T, 118 mph. Speed ratings for other tires include Q, 99 mph; H, 130 mph; and V , 149 mph. Some tires have speed ratings of W, 168 mph and Y, 186 mph.

What is W rated tyre?

So, what does tyre rating W mean? Essentially, it means that your tyres will be able to handle a specific maximum speed while carrying a load. Typically, tyres with a W rating can handle a maximum speed of 168 mph.

What does 85V mean on a tire?

Load rating: 85V. In this case, 85 means the tire is rated for 1,135 pounds (see Table 2). Multiply this by the number of tires on the car, and you get a maximum safe loaded vehicle weight of 4,540 pounds (including people, luggage, a full tank of gas, and all the loose change under the seats).

What does Zr mean on tyres?

What Is A Zr Rating On A Tyre > The letters ZR on the sidewall relate to a tyre’s speed rating, which in this case is 150mph. That means it should not be driven at speeds in excess of 150mph (240kmph) – of course, where such speeds are even legal! Before 1990, ZR was used for high-performance tyres.

What does 91V on a tyre mean?

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.

What does 89v mean on tires?

V – Speed ratings are represented by letters ranging from A to Z. Each letter coincides to the maximum speed a tire can sustain under its recommended load capacity. For instance, V is equivalent to a maximum speed of 149 mph.

What is 104h on a tire?

Those numbers refer to the load and speed ratings of the tires. In your first example 104T would mean that tire has a load carrying capacity of 2000 pounds (900kg) and a speed rating of 118 miles per hour (190 km/h). As the letters and numbers go up their respective scales the load rating and speed rating go up.
