"I enjoy the stock primacys grip levels, dont want crazy grip." OR "I need 245/40. 17"
Which is it?
Though of course you can always purposedly select such wider tire of bad as possible type + overpump it, to lessen grip to Primacies level. Doesn't sound to me as right thing to do though. Many tires are usually of more grippier rubber compound then Primacies are, and often you can get more grip even if you put them narrower then Primacies, eg. 205/50.
