Tires Speed Rating

How often do you think you're going to need a tire that's speed rated for anything over 150 mph ? Be honest and knock down your required speed rating to, say, and H-speed rated tire that's still good for 130 mph. You'll pay less and likely not notice the difference in the real world. For reference, the most common speed ratings you'll come across on the majority of tires are shown in the chart below. Speed ratings signify the safe top speed of a tire under ideal conditions. For just about any street car, a V-rated tire will be more than adequate, unless the car will actually go faster than 150 mph. Usually, most ultra-high performance handling tires have a speed rating of at least V, so while you might want the ultimate handling of that type of tires, be aware that part of what you're paying for (the speed rating) is something you'll never use. For those who want tires that make a car look different, it ends up that many get the speed rating anyway, even though they don't need it. That's not a bad thing, but also be aware that tires with higher speed ratings are usually made from a softer rubber compound and generally will have shorter UTQG tread life ratings and will not actually last as long in the real world.
