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 V rated tires?
If you feel the need to drive at or above 130 mph then you should get a “V” speed rated set of tires. If you don't plan on driving that fast, then an “H” speed rated set is the better option.
What speed are my tires rated for?
You can also possibly find the speed rating of your vehicle on the sidewall of your tire at the end of the tire size. As an example: if your tire size is "225/70R16 91S", the "S" at the end is the speed rating. Speed ratings are rated A-Z.
What speed rating is H?
130 mphAn H speed rating indicates the tire is approved for speeds up to 130 mph (210 km/h) under optimal conditions.
Do higher speed rated tires wear faster?
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 Z rated tires?
While a Z-speed rating still often appears in the tire size of some tires, such as 225/50ZR16 91W, the Z in the size signifies a maximum speed capability in excess of 149 mph; the W in the service description indicates the tire's specific 168 mph maximum speed.
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.
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 happens if you exceed tire speed rating?
What happens if you exceed your tire's speed rating? If you drive faster than the rated speed for your tires you are risking damage to the tires that could cause safety and performance problems down the road.

What does a speed rating mean on a tire?
Most modern passenger tires bear a tire speed rating, a designation indicating the tire’s designed speed capability. In other words, it’s the fastest speed a tire can handle before it does not perform as designed. Tire speed ratings do not imply that the vehicle may safely be driven at the maximum speed for which the tire is capable, particularly under adverse weather or road conditions.

Indicated by a letter, each rating corresponds to a specific speed.
Where to find speed rating on tire?
Speed rating is easy to locate because it’s usually the last item in the character sequence in the tire’s size code. For example in this tire code: “P205/60R16 82S,” S is the speed rating. To view the tire size code for your current tires, just look at the sidewall. Does the speed rating on each tire match what the manufacturer recommends? It should!
Is a tire speed rating the same as a recommended speed?
Also remember that the tire speed rating isn’t the same thing as a recommended travel speed. The rating will nearly always exceed maximum highway speed limits, but no tire or vehicle manufacturer advises driving faster than the law allows.

Can a tire lab simulate a condition?
However, it’s important to remember that the lab can’t simulate every conceivable condition. Think of your tire’s speed rating as an indicator of the product’s capability under controlled conditions (i.e. fully inflated, vehicle running properly, good weather conditions). Your tires’ actual speed capability may be less than its rated speed, since it is affected by factors such as inflation, wear, vehicle condition (including wheel alignment), driving conditions and the duration at which speed is maintained. Speed ratings do not apply to tires that have been damaged, altered, under-inflated, overloaded or repaired.
