What does the T or H mean on 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.
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 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 do the ratings mean on tires?
Load rating Every tire is rated for the amount of weight it can support, but the rating is based on an index rather than the actual weight. For example, a load rating of 92 on a typical tire for a full-size sedan corresponds to 635 kilograms (not quite 1,400 pounds). The higher the load rating, the stronger 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 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.
Is Load Range D or E better?

Why are winter tires better than other tires?
According to Bridgestone, this is because the rubber used to make these tires is softer, allowing it to grip the road better. The treads on these tires are also often deeper than usual and specialized to funnel slush and snow toward the outside edge of the tire and away from the car. If you live in an area with particularly cold and icy winter weather, you can also opt for studded winter tires.
What is tread life warranty?
A tread-life warranty is the mileage guaranteed for a specific tire. For example, if a tire has a 90,000-mile tread-life warranty, the manufacturer promises to replace the tires if they "die prematurely," as Farrell calls it, before reaching the 90,000 miles.
What does OE mean in tires?
When shopping for tires online, some tires are labeled as "replacement" and some as "OE." The OE stands for "Original Equipment" and represents the tire the manufacturer chose for the car as it rolled out of the factory. If the tire shows up as "replacement," it simply means it wasn't the original tire. This doesn't mean the tire won't perform any better or worse, but there is a greater risk it won't complement the car's intended performance.
What is the best way to keep tires inflated?
However, you can use pure nitrogen. This option is appealing because nitrogen gas is less likely to seep through the rubber, so your tires stay inflated longer. Tires filled with pure nitrogen are also less prone to deflation when the temperature changes, which can be particularly useful for racing cars or driving in extreme climates. If your tire pressure remains constant, you're more likely to see better gas mileage, which can save you money.
What is the grade of winter tires?
Winter tires may carry the letter R (106 mph) or higher. Treadwear grade: A government-required number that indicates a tire’s expected wear. A grade of 300 denotes a tire that will wear three times as well as a tire graded 100. But the numbers are assigned by tire manufacturers, not an independent third party.
How long do tires last?
