Which is higher between tire grades H and V?
2 Answers
Tire grades H and V are compared, with V having a higher speed rating. H and V represent the speed ratings of tires, indicating the maximum speed a tire can withstand. The H grade can withstand a maximum speed of 210 km/h, while the V grade can withstand up to 220 km/h. Tire speed ratings start from the letter M, with letters further in the alphabet indicating higher tire performance. However, in the tire speed rating comparison chart, there is an H between U and V. The H grade stands for "High performance," meaning tires with an H rating can support a maximum speed of 210 km/h and are considered high-performance tires, typically used in mid-to-high-end sedans. To better mitigate tire deformation and heat generation, higher speed-rated tires are reinforced in the shoulder and tread areas. This not only helps reduce deformation during rolling but also ensures more stable performance in the tire's contact area with the ground. Simply put, tires with higher speed ratings offer better grip during vehicle turns and enhanced durability.
I remember when I first started driving, I couldn't tell these speed ratings apart either. Now, after decades behind the wheel, I understand - V-rated tires are definitely higher than H-rated! V means the maximum safe speed reaches 240 km/h, while H is 210 km/h. Why go for higher ratings? Safety first on highways - better heat resistance when driving fast. But V-rated tires are usually more expensive and stiffer, might feel a bit bumpier for daily driving. Last time I changed tires, I chose V-rated - much steadier on highways, though fuel consumption is slightly higher too. My advice: choose based on your driving habits, don't just impulsively go for the higher speed rating.
