v is the speed rating on the 16inch wheel
I have seen the reviews of infinity tyres on line and there shocking but i have had a set of 4 before and they were fine
also had michelin ps2's that made my t5 v70 understeer like a pig
to be fair if i had the money it would be on yokohamas or toyos but the budget wont run to them at the moment

ps i called my insurance company and asked the question and they said if the manufacturer specified w rated tyres thats what they would expect to be fitted as a matter of course when replaced and that a dim view would be taken on lower than specified speed/load rated tyres
