What do 98V and 98H on tires mean?

[Philip]

The meanings of 98V and 98H on tires are as follows: 1. The 98 in 98V represents the load index of the tire; V indicates the speed rating, meaning the maximum speed the tire can withstand is 240 km/h. 2. The 98 in 98H also represents the load index of the tire, and H indicates the maximum speed the tire can withstand is 210 km/h. Below is more information about car tires: 1. Tires are circular elastic rubber products installed on various vehicles or machinery to roll on the ground. Mounted on metal rims, they support the vehicle body, cushion external impacts, and ensure contact with the road surface to maintain driving performance. 2. The speed rating indicates the maximum speed at which the tire can carry a specified load under specified conditions. Different tires have speed ratings marked with English letters on their sidewalls, such as Q for 160 km/h, R for 170 km/h, S for 180 km/h, and so on.

Last year when I changed tires, I researched these markings. The numbers 98V and 98H on the tire represent the load capacity, with 98 corresponding to a maximum load of 750 kg per tire, while the letters V and H indicate the speed rating. H-rated tires are suitable for daily driving up to 210 km/h, whereas V-rated tires can handle speeds up to 240 km/h. The key is matching the tire to the vehicle type. For my family SUV, I simply chose 98H tires since I rarely exceed 200 km/h, but sports or performance cars must use V-rated tires. Once, a friend mistakenly installed H-rated tires on a sedan, and the steering wheel shook violently at high speeds—only after inspection did they realize the speed rating was insufficient. When selecting tires, don’t just focus on tread patterns and size; these small markings on the sidewall are crucial for safety performance.

The alphanumeric combination on the tire sidewall reminds me of my experience at the tuning shop. The '98' in 98V indicates the tire can withstand a load of 750 kg, while 'V' represents a maximum permitted speed of 240 km/h. The 'H' in 98H corresponds to a speed limit of 210 km/h. These ratings are linked to the car's power. For example, my 1.8T car originally came with 98H tires, which were sufficient, but after an ECU remap, the technician insisted I upgrade to 98V tires. Once, while helping a neighbor check his tires, I realized he didn't understand these parameters and ended up buying lower-rated tires, which developed bulges within just a month. Now, when selecting tires, I always make a point to remind others: the load index affects stability, and the speed rating impacts high-speed grip.

Last time, the mechanic taught me how to read tire markings. The number 98 in 98V indicates a single tire load capacity of 750 kg, and V means it can withstand speeds up to 240 km/h. 98H has the same load capacity but a maximum speed of 210 km/h. This relates to differences in tire rubber compounds—V-rated tires have stiffer sidewalls to resist deformation. I always check this parameter before long trips, especially when fully loaded with luggage, as insufficient load capacity can cause the sidewalls to overheat. I remember once taking sharp turns on a mountain road, and it was the strong support of the V-rated tires that kept me steady. Don’t skimp on this when choosing tires—higher ratings mean more reliability in extreme road conditions.

After researching tire parameters, I found that the difference between 98V and 98H lies in the speed limit, with the former supporting 240 km/h and the latter 210 km/h. The load index of 98 is the same, approximately 750 kg. For my usual gentle driving, 98H is sufficient. However, when borrowing a friend's sports car, I realized I had to switch to V-rated tires, as the car would start to feel unstable above 150 km/h otherwise. Now when buying tires, I look for all-steel belt construction, as V-rated tires generally have two additional layers of cord fabric to enhance impact resistance. During a heavy rainstorm on the highway, the deeper tread grooves of the V-rated tires quickly dispersed the water film, preventing hydroplaning and giving me peace of mind.

As someone who frequently drives on mountain roads, I pay special attention to tire specifications. Both 98V and 98H indicate a load capacity of 750 kg, but the H rating has a speed limit of 210 km/h while the V rating goes up to 240 km/h. The former has softer rubber for better fuel efficiency and comfort, while the latter features reinforced construction for better resistance to deformation and a firmer response over speed bumps. When choosing tires, I prioritize the road conditions I frequently encounter: for city commuting, 98H is economical enough, but for continuous mountain switchbacks, 98V is a must. Once, I made the mistake of opting for a cheaper, incorrect rating, and the braking distance at high speeds noticeably increased. I recommend regularly checking the sidewall specifications and replacing tires promptly if wear exceeds the limit.
