When a vehicle moves at higher speeds, the wheels turn faster and more heat is generated in friction on the road. If the tyre can’t cope with this extra heat then they risk failing, which is incredibly dangerous when moving at high speeds.
The tyre speed rating indicates the top speed the tyre can support under its approved load capacity. For example, a tyre with a speed rating of H can go up to 130mph.
In knowing the tyre speed rating, you can safeguard your tyres and keep yourself safer when driving.
