When I asked my tyrefitter / MOT tester about 15 years ago I was told it was a load rating (not just speed).

Doctor Gollum is right though - it will be in the manual.........

V speed rating is 149mph.  If you drive faster than that Ray, then go higher W 168 mph or Y 186 mph.   ::)  ;D

As said see what the manual says.  :y

Regardless of the speed limit, the tyres need to at least match the maximum attainable speed AND maximum axle rates of any given vehicle.

This is why winter tyres often come with a significantly lower speed limit as they are often only H rated.

Also a 3.0/3.2 Omega will cruise on the naughty side of 140mph.

Fit under rated tyres and watch what happens if you're involved in a prang. Regardless of fault you're uninsured and instantly guilty of driving a defective vehicle.

You MUST match or exceed what the manufacturer states, irrespective of speed you drive at.

In most cases, not doing so will null and void the insurance.

This applies to speed and load ratings.


The single exception is Z rated, where in many cases Y is permissible
