Just installed Continental Extreme Contact Sport Plus Tires on 17" Rims. My prior Bridgestone's were set to 29F and 36R pressure per the owner's manual. The Tech set the new tires at 34 F and R. The car is 20 years old and maybe there is a reason for the change in pressure. The car handles fine with the 34# pressure but not not driving hard during the recommended break in period. Any recommendations from those who have been driving their Boxsters. Thanks!
