To support running at higher speeds, V-rated tires will have a stiffer sidewall and slightly firmer ride than H-rated tires. For normal driving conditions the H-rated tire will provide a more comfortable ride and the V-rated should give slightly better handling.
Likewise, What is T speed rating?
T — Up to 118 mph. H — Up to 130 mph. V — Up to 149 mph. W — Up to 168 mph. Y — Up to 186 mph.

Moreover, What does 120 load index mean on tires?
Light truck tires have two load indexes on the sidewall of the tire, unlike passenger tires, which only have one. … For example, a light truck tire with a load index of 120/116 means a load capacity for a single tire of 3,086 pounds and a load capacity of 2,756 pounds for two tires.
What does the S and T mean on tires?
S/T tires are all season, street or sport truck tires. They are designed specifically for performance pickup trucks, sport utility vehicles, and crossover vehicles.
What does Z rating mean on tires?
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.
Does higher speed rating mean better tire?
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 does V rating mean on tires?
Speed Rating V
Once the highest speed rating a tire could have, “V” used to represent a maximum of 149 mph (240 kph) or more. Nowadays, it means 149 mph but no higher.
Does tire speed rating affect ride?
Speed ratings affect more than just speed, they also contribute to ride comfort, wear, and cornering capabilities. In general, the higher the speed rating, the better the grip and stopping power, but the lower the tread life.
Is Load Index 121 a 10-ply tire?
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’s better load range D or E?
For a given brand and size tire, the load range E has a higher maximum load capacity than the load range D. The E tire is built and rated for 80 psig, while the D tire is (as I recall) built and rated for 65 psig maximum inflation pressure.
Is Load Range D better than C?
Expert Reply: The difference between an load range C and load range D tire in the same size is the capacity and psi rating. The two tires will still have the same dimensions and fit on the same wheel. The D rated tire has a higher capacity.
Can I use 235 tires instead of 225?
Are 225 and 235 Tires Interchangeable? Yes, they are. However, this is only possible if your car’s rims can accept the larger millimeter.

| T | Up to 118 mph |
| U | Up to 124 mph |

What happens if you exceed tire speed rating?
The speed rating is there to let you know that you shouldn’t exceed that speed with that tire. If you do for a sustained period of time the air in the tire will heat up and expand causing the tire to explode. It is pretty simple.
What does the R in Rist stand for?
Since clamping force is the key and the correct torque doesn’t guarantee anything, TIA came up with the acronym RIST to help technicians remember the recipe for installing wheels and rims. R = Remove debris from mating surfaces. … – R – Removing debris from the mating surfaces reduces the chances of joint settling.
What does the last letter on a tyre mean?
The final letter represents the Speed Rating of the tyre. This is the maximum speed that the tyre can cope with under its maximum load. Each letter represents a corresponding speed. The example we are using has an H rating which equates to 130mph (210kmh).
Can I put a higher speed rated tire on my car?
Experts frown on the practice of mixing and matching lower and higher speed-rated tires on one vehicle. It can lessen your car’s ability to handle wet road conditions. Additionally, your maximum mph will be based on the lowest speed-rated tire you have.
Will 10 ply tires last longer?
most 10 ply tires have a harder rubber compound and will last longer than a 6 ply tire.
What does 10 PR mean on a tire?
“Q” refers to the tire’s speed rating. In this case, the tire is rated at 99 mph for continuous use. The higher the letter, the faster the tire is rated to travel. 10 PR refers to the ply rating of the tire. A 10-ply rated tire is the same as a Load Range E tire.
What does 121 118q mean on a tire?
The 121 is the Load Index of the tire, which determines the amount of weight the tire can safely handle. Light Truck (LT) tires will typically have a dual rating such as 121/118. … Light Truck (LT) tires will typically have a dual rating such as 121/118.
Is 80 psi too high for tires?
