What does VWH mean on tires?
3 Answers
Tire VWH refers to the speed rating of the tire. The further back the letter is in the alphabet, the higher the speed it represents. Specifically, V represents a speed of 240 km/h, W represents 270 km/h, and H represents 210 km/h. The functions of tires are: 1. To cushion the impact experienced by the vehicle during driving; 2. To ensure good comfort and smooth driving; 3. To maintain good adhesion between the wheels and the road surface, improving the vehicle's traction, braking, and passing performance; 4. To bear the weight of the vehicle. Precautions for tire use include: 1. Pay attention to the degree of tread wear; 2. Avoid excessively high or low tire pressure; 3. Regularly remove debris from the tread to prevent punctures; 4. Rotate tires periodically to prevent uneven wear.
I remember when helping a friend check the tires, I noticed many people confuse the markings. VWH might refer to a combination of tire speed ratings, but the standard format usually consists of separate letters. For example, V represents a maximum safe speed of 240 km/h, W stands for 270 km/h, and H indicates 210 km/h. It could be a typo or a brand abbreviation, but tire specifications like 215/65R16 V or W require clear reading of the sidewall markings. Every time I change tires, I emphasize that safety comes first—matching the speed rating to the vehicle's performance to avoid skidding risks. If you find unclear markings, go to a professional shop immediately for confirmation without delay. Otherwise, there's significant hidden danger when driving at high speeds.
As a car enthusiast who frequently changes tires, the notation 'VWH' seems a bit odd. Tire specifications usually include width and speed ratings like 245/50R17 V, where 'V' indicates the tire is designed for speeds up to 240 km/h. It might be a typo and actually meant to represent an H or W speed rating. The self-check method is quite simple - just squat down and look for the small raised letters on the tire sidewall to directly read the speed symbol. For routine maintenance, regularly inspect tread depth and check sidewalls for cracks to ensure driving stability.
