## What is the speed rating on tires?

A tire’s speed rating indicates the optimal speed that the tire can safely maintain over time. In short, it’s the fastest speed a tire can handle before it no longer performs as designed. The higher the speed rating, the better control and handling you’ll have at higher speeds.

## What does standard H mean?

In summary, H and T markings on tires refer to the maximum speeds they can support – given payload capacity, recommended tire pressure, and ideal road conditions are met. H-rated tires can withstand up to 130 mph (210 km/h), with T-rated ones supporting up to 118 mph (190 km/h).

**What is H tyre size?**

Letters ranging from A to Z represent the speed rating. Each letter denotes the maximum speed a tyre can sustain under its recommended load capacity. In our example, “H” is equivalent to a maximum speed of 130 mph (209 kph).

### What does the Z mean on tires?

SPEED RATING Z A “Z” rating can mean different things. While it nearly always means a high performance tire for high-performing sports cars, “Z” may actually appear in the middle of a tire’s size information. When it does, it represents either a maximum speed of more than 149 mph (240 kph) or 186 mph (300 kph).

### Can I fit a higher speed rating tyre?

However, for cars the fitting of a higher speed rating is fine. If you do choose a tyre with a higher speed rating though, we recommend that you match the tyres across the axels, avoiding having different speed ratings fitted on either side of the car.

**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).

#### What is the difference between AT and HT tires?

AT tyres have a deeper and more aggressive tread than HT tyres. This provides greater grip in off-road conditions. Generally speaking, the stronger, thicker sidewalls of an AT tyre make them less likely to suffer damage caused by common hazards encountered off-road, such as rocks, ruts and tree roots.

#### Is E or F tires better?

F-load range tires allow for higher carrying capacity at a higher inflation pressure compared to tires of the same size with an E-load range.

**What does h mean on a car speedometer?**

It represents a maximum speed of 130 mph (210 kph) and is commonly found on sports sedans and coupes. In earlier incarnations of the speed rating system, “H” stood for “high performance,” which is why it maintains an unusual position in the speed rating spectrum today.

## What does the “h” speed rating mean?

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 does h+ mean in mobile signal?

Meaning of H+ in Mobile Signal This is enhanced HSPA. It is faster than basic HSPA (as explained above). Relatively speedier data transfer in H+ will make your video to download or stream much more smoothly.

**What speed does h mean on a tire?**

For example, “H” would translate to a tire that can only handle speeds up to 130 mph (or 210 km/h). Where is the speed rating located on a tire?
