Tyre Ratings & Best Tyres for Road Use — With Real Vehicle Examples

1. Tyre Ratings: What to Look For These ratings appear on the tyre sidewall and help you judge quality, safety, and performance. Treadwear Rating This tells you how long a tyre is likely to last. The higher the number, the longer it should last. A treadwear of 400 means the tyre will last about 4 times longer than a baseline test tyre. Traction Rating This shows how well the tyre grips on wet roads. The grades are: AA (excellent), A (good), B (moderate), and C (poor). Temperature Rating This tells you how well the tyre resists heat. High heat resistance means the tyre won’t overheat and burst at high speeds. Grades: A (best), B, and C. Load Index This number shows how much weight one tyre can safely carry. You must match this to your vehicle's weight class. Speed Rating This tells you the maximum speed the tyre can handle safely. For example, H = 210 km/h, T = 190 km/h, etc. 2. Best Tyres for Personal Vehicles (By Model) a. Toyota Corolla / Honda Civic Recommended Tyre: Michelin Pr...
