It should! The rating will nearly always exceed maximum highway speed limits, but no tire or vehicle manufacturer advises driving faster than the law allows. Speed ratings are the product of laboratory testing — with simulated speeds and loads.
Industry standards govern the process of reaching and maintaining a given speed during a test. Speed ratings do not apply to tires that have been damaged, altered, under-inflated, overloaded or repaired. Each letter corresponds to a specific speed. In general, that speed goes up as the rating advances alphabetically.
This was for tires whose maximum sustained speed was mph kph or more. Standard Load: This means just what it says. If the tire was made for heavy loads or light loads, those words might appear on the sidewall. Treadwear This indicates the tire's wear rate as determined by DOT tests. The higher the number, the longer a tire should last, depending, of course, on your driving habits.
A should last four times as long as a tire rated If you like to peel out from stoplights, though, you'll pay the price in more frequent tire changes. Traction A: This is a measurement of how quickly the car will brake on wet pavement. In this case, an A is not the top grade: AA is best. C is the lowest. Temperature A: This shows a tire's ability to stand up to heat.
An A here is the top grade, and should be least affected by high temperatures. Again, C is the lowest grade. Knowing all of this, how can you match your tire purchase to your driving habits? First, consider your climate.
Do you deal with the scorching heat of Phoenix or the breathtaking cold of Winnipeg? Choose a tire that functions well in those conditions. Second, consider your driving habits. Do you push the envelope on speed? Choose a tire that will help you keep the car under control; that is, one with better traction. Third, consider aesthetics. If you really like the low-profile look, shop for a tire with a low profile rating, but know that you're buying yourself a rougher ride when you do so.
And of course, the best tire for the money may not hit all your requirements on the head, but a general-purpose all-season radial could be the cheapest option, thanks to the volume demand.
The first number indicates load carrying capacity if the tire is installed on a truck with a single-wheel rear axle, and the second number applies when the tire is used in a dual rear application. 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 mph. Even though a tire can perform at this speed General Tire does not advocate exceeding legal speed limits.
It is also important to note that speed ratings only apply to tires that have not been under-inflated, overloaded, damaged, or altered. General Tire uses cookies like most sites to continually improve your experience. There are Superstitious Much?
