What does 98H stand for on a tire?
Load index. This is a numerical code corresponding to the maximum load the tire can carry. H = Speed rating. This letter indicates the maximum speed the tire is certified to carry its load. H, for instance, is up to 130 mph (210 km/h). 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.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.This number indicates the size of the rim that the tire can be mounted onto. Load index. This is a numerical code corresponding to the maximum load the tire can carry. H = Speed rating. This letter indicates the maximum speed the tire is certified to carry its load.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.
What does the H mean on my tires?
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). It cannot be recommended ideally. The lower-rated tyres can compromise handling, safety, and performance. The failures happen when you are at higher speeds.A vehicle originally delivered with tires rated H or V will offer not perform as well with S-rated tires installed (see the chart below). Steering, braking, handling and stability can all be affected, because the sidewalls of an S-rated tire are not as stiff as those of an H- or a V-rated tire.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 (130 mph) prioritize comfort and longevity, lasting 61,080 miles on average with softer sidewalls for better shock absorption and quieter rides. V-rated tires (149 mph) excel in performance and handling, offering superior grip and cornering capabilities but with shorter tread life at 48,260 miles average.
Is speed rating H good for tires?
An “H” rating means the tire can manage speeds up to 130 mph. While most people never drive that fast, the speed rating also reflects the tire’s overall performance. A higher rating often means better handling and responsiveness, while a lower rating might be fine for everyday commuting. One of the most important aspects of any tire is its speed rating. The wrong tires with a less-than-adequate speed rating for your vehicle can cause safety issues, including tire failure and a loss in fuel efficiency.Typically, the higher the speed rating, the better the grip and stopping power, but the lower the tread life. You can always increase the speed rating of the tires on your vehicle for improved performance, but can never decrease it without reducing the vehicle top speed to that of the lower speed rating selected.The 3% rule states that when replacing tires, the new tire’s diameter should not differ from the original by more than 3%. This guideline helps maintain proper vehicle performance, safety system functionality, and speedometer accuracy.
Should I get V or H rated 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. Speed Rating H provides balanced performance, versatility, and comfort suitable for everyday driving scenarios, while Speed Rating V delivers high-performance capabilities, superior handling, and a sportier driving experience.What is the difference between 98T and 98H tires? T is 118 MPH max, H is 130 mph max speed rated. For the most part, a tire’s max speed increases in direct correlation with where it’s letter designation sits in the alphabet.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.The primary distinction between 89H and 91H tires lies in their load-bearing capabilities. An 89H tire can support a slightly lower weight compared to a 91H, affecting how your vehicle handles under load. This difference might seem minor, but it can be crucial for vehicles regularly carrying heavy cargo or passengers.
What is the top speed of a 98h tire?
So, a tire with a 98H rating can carry up to 1,653 pounds and is safe for speeds up to 130 mph. Generally, the higher in the alphabet a tire is rated, the better it will manage heat and faster speeds.
Can I fit H-rated tyres instead of V?
Using tyres with different speed ratings can also cause uneven wear and tear on the tyres, leading to a shorter lifespan and potentially compromising the safety of the vehicle. The only exception to this is a winter tyre. It is not recommended that you mix and match tyres that have different speed ratings. Most tyre manufacturers recommended that speed-rated tyres be replaced in sets of four. If replaced in pairs, the new tyres should be of the same or higher speed rating.
