Shelf life and maximum speed of tyres

Knowing the shelf life and maximum speed of tyres is crucial for a safe driving experience. 

Did you know that the speed rating for each tyre is indicated by a letter on the tire wall, ranging from L to H? 

Additionally, the tire's shelf life is indicated by a four-digit number on the wall, with the first two digits indicating the week of manufacture and the last two indicating the year. It's important to note that a tire's validity is typically two to three years from the date of manufacture.

Therefore, it's crucial to ensure that your tyres can withstand the pressure of high speeds to avoid accidents. 

Many tyre explosions occur due to increased speed, and this can be prevented by checking the letter indicated on your tyres. Each wheel or tire has a certain speed rating, with the letter L meaning a maximum speed of 120 km/h and the letter H meaning above 210 km/h. 

The letter L means a maximum speed of 120 km.

... And the letter M means 130 km.

And the letter N means 140 km

 And the letter P means 150 km.

And the letter Q means 160 km.

The letter R means 170 km.

And the letter H means above 210 km.

Stay safe on the road by being aware of your tire's maximum designed speed and shelf life.
