impreza tyre rating.

[jazzy29]

Hi all, what do most impreza turbo drivers run their tyres on? ie. v or w
rating? (205/50/16)
I understand the rating thing but what is the problem with running v
rated? and what sort of speeds do they run to safely?
thanks in advance.

V is up to 149 MPH..

It is not just the speed rating that's important. Each rating has to
do with sidewall flexure and tread compound. You should stick with the
speed rating that the manufacture put on the car. That way you retain
the same handling characteristics with respect to safety. Most tire
retailer will not put a lesser tire on your car for fear of a lawsuit
since in most states it is illegal.

Do you have a list of states where speed ratings below that of what is
supplied with a vehicle is illegal. All I can find is a law in Maine that
may have been reversed recently. There are not many snow tires that carry a
V, W, or Y rating. Also here in Illinois, the maximum speed limit is 65
m.p.h. so I would wonder how any state could require tires that exceed the
maximum speed limit by double.
