Tire Speed Rating

The tire speed rating, denoted by a letter in the tire designation on the sidewall, indicates the maximum speed for which the tire is designed to perform safely. Here’s a summary of common tire speed ratings along with their corresponding maximum speeds:

• P: Up to 150 km/h (95 mph)
• Q: Up to 160 km/h (100 mph)
• R: Up to 170 km/h (105 mph)
• S: Up to 180 km/h (113 mph)
• T: Up to 190 km/h (118 mph)
• U: Up to 200 km/h (125 mph)
• H: Up to 210 km/h (130 mph)
• V: Up to 240 km/h (150 mph)
• W: Up to 270 km/h (168 mph)
• Y: Up to 300 km/h (186 mph)
• Z: Over 300 km/h (186 mph)

It’s important to note that the speed ratings are not necessarily directly proportional to the alphabetical order. The ratings evolved over time, reflecting advancements in tire technology and the increasing performance capabilities of vehicles. When selecting tires, it’s crucial to choose ones with a speed rating that matches or exceeds the maximum speed capabilities of your vehicle to ensure safety and optimal performance.
