What does 99H mean for tires?
Using the above example, you would also see ’99H’ on the tire sidewall. H is the speed rating that tells you the maximum service speed for a tire. Letters ranging from A to Z represent the speed rating. Each letter denotes the maximum speed a tyre can sustain under its recommended load capacity. In our example, “H” is equivalent to a maximum speed of 130 mph (209 kph).Higher speed ratings, like H or ZR, can handle far beyond a normal highway speed. For example, “H” would translate to a tire that can only handle speeds up to 130 mph (or 210 km/h).For example, “H” would translate to a tire that can only handle speeds up to 130 mph (or 210 km/h).H-Rated Tires: This is a perfect, average tire for most sedans and commuter vehicles. It might not seem to fit in our chart, but the tire speed rating “H” is rated for up to 130 mph. T-Rated Tires: This tire is often recommended for family sedans and vans. It’s rated for up to 118 mph.
What is the difference between 99T and 99H tires?
The choice between H and T tires is actually based on speed ratings: while H-rated tires allow a top speed of 130 mph, delivering superior handling and heat resistance. T-rated tires max out at 118 mph and thus favor durability and comfort for everyday use. H-rated tires are thoroughly tested to safely handle speeds up to 130 mph, while V-rated tires show reliable performance at sustained speeds up to 149 mph, which is an important distinction for vehicles that travel at higher speeds.Overall, H-rated tyres are able to deliver better handling, braking, cornering, and faster acceleration than their T-rated counterparts.The Michelin Defender T+H: a tire that combines all-season traction, class-leading ride comfort, and an extremely long projected service life—all from one of the best brands in the business.
What does 99H mean on tires?
Understanding Tire Load Indexes: So, let’s take an example: a tire with the size of 235/55R17 99H has a load index of 99, meaning it can carry a load of 1,709 pounds. The higher the load index, the higher the tire’s capacity to carry weight. A tyre’s load index is a number that can be used to look up the maximum amount of weight that a tyre can bear at its speed rating when inflated to its maximum pressure. This number, which is usually between 75 and 100 for passenger cars, is not stated in pounds or any other unit of measurement.T and 102H are service descriptions. Load Index, what this means is, the tire is capable of carrying weight up to, 1,874 lbs per tire. The T and H are speed Ratings, this indicates that a tire is capable of speeds up to, 118 mph and 130 mph (respectively).
What does T&H stand for on tires?
The T and H markings on the tires means SPEED ROTATION, H Stands for 130 miles per hour the tire and handle, While T stands for 118 miles per hour max speed. Light truck drivers should look for symbols N, P, Q, R, S, T or H. If you’re replacing tires and think you may want a lower- or higher-speed-rated tire, it’s best not to mix and match.
Which is better, H or T-rated tires?
Overall, H-rated tyres are able to deliver better handling, braking, cornering, and faster acceleration than their T-rated counterparts. The tread of H/T tires is much smoother, with more shallow grooves than A/T tires, causing less friction with the road which makes for a smoother, quieter ride, lengthens the tire’s life and increases the vehicle’s fuel economy.Larger tires require more energy from the engine to move the vehicle compared to smaller tires, resulting in increased fuel consumption. Smaller tires and wheels demand less engine output, making them more suitable for navigating stop-and-go city traffic efficiently.It is not recommended to fit new tyres with a lower speed rating to what is recommended for your vehicle. Whilst choosing to equip your car with a higher speed rating is safe, replacing your tyres with those of a lower speed rating will compromise the safety of your vehicle.Generally, you don’t want to go with tires that have a diameter that is more than 3% different from the factory tires. It’s also a good idea to consult with a trusted mechanic before switching to larger or smaller tires.
Which tyre is better, H or V?
For example, a tyre with a speed rating of H can safely maintain a speed of up to 130 mph, while a V rated tyre can handle speeds up to 149 mph. No, you should NEVER do this. Using a tyre with too low a speed rating for the car increases the risk of tyre failure at high speeds. Also, doing this can potentially invalidate your insurance.
