What is the meaning of 225 55 r18 98H?
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. 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.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.Speed rating H If you recall from earlier, the “H” speed rating doesn’t appear after “G” but between “U” and “V. It represents a maximum speed of 130 mph (210 kph) and is commonly found on sports sedans and coupes.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).
What does 98h mean on a Michelin 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). So, a tire with a 98H rating can carry up to 1,653 pounds and is safe for speeds up to 130 mph.
What is the speed rating 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. Sticking with H-rated tires comes at a cost. While we found prices are similar to S- and T-rated tires, H-rated tires didn’t last as long in our treadwear test–an average of 49,180 miles, versus 61,080 for our S- and T-rated tires. V-rated tires had an even shorter tread life of 48,260 miles.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.Generally, the higher in the alphabet a tire is rated, the better it will manage heat and faster speeds.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.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.
