What does 235 55R17 99H mean?
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. 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.For passenger vehicles, load index ranges from 75 – 105. H” represents the speed rating, which is how fast the tires can go based on their load capacity. This rating ranges from A – Z. H” indicates a speed rating of up to 130 mph.Using 98 as our example load index, once again, our tire has a maximum load capacity of 1,653 pounds. The speed rating is a letter assigned to the wheel to identify the maximum speed at which the tire is rated as running safely. Using H as our example speed rating, our tire has a maximum speed of 130 miles per hour.What Tire Speed Rating Do You Need? Even in states where rural speed limits are 75 mph, most drivers will stay well below the speed limitations of H-rated tires. Commuters and family car drivers will likely be quite satisfied with S or T tires.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.
What does H mean on tyres?
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).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’s the difference between 99T and 99H?
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. Shane N.H-rated tires typically last longer, averaging approximately 61,080 miles compared to 48,260 miles for V-rated tires. This advantage comes from harder rubber compounds optimized for everyday driving rather than maximum grip. V-rated tires use softer compounds that prioritize road adhesion over longevity.H-rated tires are designed for speeds up to 130 mph, while T-rated tires are rated for speeds up to 118 mph. H-rated tires generally offer better handling and performance, while T-rated tires typically provide better comfort, fuel efficiency, and longevity.In the battle of T and H ratings, H is generally perceived as being better. H-rated tyres are effectively able to cope with 12mph faster speeds, can cope with greater friction at all speeds, and have significantly more capacity for heat resistance.AT tyres have a more aggressive and deeper tread than HT tyres, which gives them more traction for off-road driving. AT tyres are generally an ideal option for 4WD owners and weekend off-road enthusiasts thanks to their durability, longevity, and on- and off-road performance.
What does the 99H mean on a tire?
R17 99H- The load index (99) is the tire size’s assigned numerical value used to compare relative load carrying capabilities. The higher the tire’s load index number, the greater its load carrying capacity. The higher the tire’s load index number, the greater its load carrying capacity. A tire with a higher load index than that of the Original Equipment tire indicates an increase in load capacity.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.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 is the code H on a tyre?
Compare the letter code to the recommended speed rating for your vehicle. To elaborate with an example, if the sidewall of the car tyre displays a tyre speed rating H, it signifies that the tyre can handle a maximum speed of 210 km/h. Generally, the higher in the alphabet a tire is rated, the better it will manage heat and faster speeds.
