What does 225 55R18 98h mean?
R stands for “Radial” and the last two figures 18 indicate the wheel diameter in inches. The size ends with the load index 98, which is the maximum weight that each wheel can support, and the speed rating H, which is the maximum speed at which the tire is approved for use. In 215/65R16 98H, the letter H stands for a speed rating of up to 130 mph. Standard speed ratings include: S: Up to 112 mph. T: Up to 118 mph.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).
What does 98s mean on a tire?
In this case, the number 98 refers to the tire’s load-carrying capacity. Each number corresponds to a specific weight rating, but it’s not as intuitive as some other numbers (for example, 98 means the tire can hold 1,653 pounds). Tires for your tire size 225/55R18 98H The 225/55R18 98H tire has the following features: the first three digits 225 refer to the width of the tire in millimetres. The second two-digit number 55 refers to the ratio between the height of the sidewall and the width of the tire.
What is the top speed of a 98h tire?
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. 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.Confusingly, W-rated tyres are rated at a higher speed in excess of 168mph. Y-rated tyres are rated in excess of 186mph.
Which tyre speed rating is best?
Most standard consumer vehicles fall under the speed rating of S or T (for 112 or 118 mph limits). However, if you drive a high-performance vehicle or a sports car that often have wide diameter tyres you may need to opt for a rating of W, Y or (Y). 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.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.
Are H-rated tires good?
Tyres with an H speed rating can cope with speeds of up to 130mph. These tyres are a good choice for people who drive at mid-range speeds and they offer solid handling, cornering, and braking performance. Exceeding your tire’s speed rating can cause excessive heat buildup, which may lead to tread separation, blowouts, or tire failure. It’s unsafe and should be avoided.You should only use tyres with speed ratings that are recommended by your manufacturer. Mixing tyres on your vehicle isn’t just inadvisable, it can be dangerous.
What does 98h mean on tire size?
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). R stands for “Radial” and the last two figures 17 indicate the wheel diameter in inches. The size ends with the load index 98, which is the maximum weight that each wheel can support, and the speed rating V, which is the maximum speed at which the tire is approved for use.
Which tyre is better, H or V?
H Rating: Can provide extended tread life and durability with proper maintenance. V Rating: Typically has a shorter tread life due to the higher performance and grip characteristics. 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.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).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.
