What is the tyre speed rating?
Ratings are determined by the results of practical tests carried out by engineers when new tyres are designed and manufactured, to ensure they can safely maintain use at the maximum speed it is rated at when carrying a determined amount of weight.[/vc_column_text]
Where can I find my tyre’s rating?
Most standard consumer vehicles fall under the speed rating of S or T (for 112 or 118 mph limits). However, if you drive a high-performance vehicle or a sports car that often have wide diameter tyres you may need to opt for a rating of W, Y or (Y).[/vc_column_text][/vc_column][vc_column width=”1/2″]

What happens if I choose a tyre with the wrong speed rating?
Installing the wrong tyres could void your manufacturer’s guarantee and also invalidate your insurance in the event of a claim. In the worst case, tyres with the wrong rating could cause a blowout or a serious incident.[/vc_column_text][/vc_column][vc_column width=”1/2″]
How do I know that I have the right tyres for my vehicle?
What you need to remember…
You should not be exceeding the national speed limit. Even in a controlled environment, such as a race track, you are still at significant risk.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column]
