What does H mean on a tire?

“H” represents the speed rating, which is how fast the tires can go based on their load capacity. This rating ranges from A – Z. “H” indicates a speed rating of up to 130 mph.

Which is better H or T-rated 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.

What does H and V stand for on tires?

An “H” rated tire is designed to operate at a maximum speed of 130 mph. A “V” rated tire on the other hand is designed to operate at a maximum speed of 149 mph, almost twenty miles an hour more than the “H” rated tire.

What speed are H tires rated for?

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.

Are H rated tires good?

H-Rated Tires: This is a perfect, average tire for most sedans and commuter vehicles. It might not seem to fit in our chart, but the tire speed rating “H” is rated for up to 130 mph. T-Rated Tires: This tire is often recommended for family sedans and vans. It's rated for up to 118 mph.

How to Read a Tire Size

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 I mix H and V 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.

What does R mean on a tire?

This is indicated in percentage of the tire width. “R” stands for the construction method of the tire indicating the tire is a radial tire. The following two numbers (16) indicate the diameter of the wheel rim in inches. The next two or three numbers (94) indicate the load index of the tire.

What are Z rated tires?

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).

Do higher speed rated tires last longer?

They're also about ride comfort, wear and cornering ability. Typically, the higher the speed rating, the better the grip and stopping power, but the lower the tread life.

What are V rated tires?

What this tire speed rating ensures is that the tire can sustain the maximum speed specified for an indefinite duration. This means that a tire with a V-rating, for example, can be driven at 149 miles per hour until it wears out!

What is Load Range E?

Therefore load range simply tells how tough the tire is and the allowable PSI. For example, an “E” load range indicates that a tire is equivalent to a 10-ply construction tire. In realitly, this tire is not built with 10 plies, but rather one or two plies of equivalent strength.

What does W mean on a tire?

The letter W denotes the maximum speed rating, which translates 168 mph—not something intended for mom's minivan. See our list of speed ratings below, which range from a low of "L" (just 75 mph for some off-road tires) to a high of Y (186 mph).

Can I use ZR tires instead of R?

R indicates that the structure is RADIAL. So, VR indicates that the tyre has a RADIAL structure and a speed index equal to V. There is therefore no difference between a ZR or an R tyre with the same speed index.

What does HT mean on a tire?

H/T (Highway Terrain) Tires for Daily Commute and Highway Driving.

What does P mean on tires?

P stands for passenger vehicle tire. P-class tires include cars, SUVs, crossovers, minivans and smaller pickup trucks. LT means light truck tire, designed for vehicles that are capable of carrying heavy loads, towing trailers, or for those looking for an extra heavy duty option.

What does XL mean on a tire?

XL (or Reinforced) tyres are 'extra load' tyres – they indicate that a tyre is reinforced to be able to withstand a higher load than other tyres of the same size.

Do all 4 tyres need to be the same speed rating?

Bear in mind that all tyres must be appropriate for the vehicle and you should drive no faster than your lowest rated tyres. We would always recommend that the same size and type of tyre, with the same speed ratings, are fitted on all tyres.

Can I use W rated tires instead of V?

V means that vehicles can safely use the tire with a top speed higher than 149mph. The rating W shows that the tire is safe to use for a vehicle with a top speed of 168mph.

What happens if you mix speed ratings on tires?

“If tires of the different speed ratings are mixed on the same vehicle, remember that the tires may vary in ride, handling or other performance characteristics. Thus care should be taken when mixing tires of different speed ratings on the same vehicle.”

Which is better 6 ply or 8 ply tires?

Actually the 6 ply will last longer than the 8 ply. The reason is the extra size of the body plies in a trailer tire will actually produce more heat while rolling than a 6 ply rated tire. I definately recommend radila and not bias ply construction. Radial tires wear much better.

Are 10 Ply tires better?

10-ply tires are way beefier than 4-ply tires which means that they ought to last a lot longer if used for off-roading, hauling, or towing purposes. 10 ply tires excel when it comes to towing and hauling because they are better able to control the load without swaying at speed.

Are 12 ply tires good for towing?

Load Range F can also be classified as 12 Ply tire. These Load Range F tires have a maximum load index of 95 PSI and are the perfect choice of tire for towing very large trailers and trucks.

What does 105 h mean on tires?

For passenger vehicles, load index ranges from 75 – 105. “H” represents the speed rating, which is how fast the tires can go based on their load capacity. This rating ranges from A – Z. “H” indicates a speed rating of up to 130 mph.

What does 92y mean on a tire?

In this case, the 92 means it can support 1,389 pounds. The Y is the speed rating, or the maximum speed the tire was designed to withstand and maintain. Back to the Z. The letter used to designate the highest possible speed rating, and it meant the tire could withstand more than 149 mph.
