Currently have 262,000 miles on 2002 Infiniti Q45. I have purchased a set of 255/45/18 tires 4 times for my 2002 Infiniti Q45 Sport. There went on the stock 18 rim. I got 40-45,000 miles on each set. I ran them at 40psi for mileage purposes. There was no abnormal wear from this higher psi, but it did help my mileage.
I live in Sacramento Ca and snow is not an issue. Also, not alot of rain driving. When it did rain I felt complete safe with these tires.
I drive for mileage so can't comment on the agressiveness of the tire. But it gripped very well when diving into cloverleaf exit ramps!
This tire is an outstand value for the money!
I am currently running the 245/50/18 kuhmo to get the largest diameter possible that would fit.
