Misinterpreting this symbol can lead to mismatched expectations regarding vehicle behavior at higher velocities. T: 190 km/h (118 mph) – Common on family sedans and minivans.
V: 240 km/h (149 mph) – Encountered on sporty compacts and premium touring tires. Heat is the primary enemy of a tire, and exceeding the rating pushes the tire past its thermal dissipation capacity, leading to degradation or failure.
