also taking of any turbos, superchargers and NA tune kits will reduce tire wear because more power equals more spin of the wheels which makes the tire life go down. An example is, the Pescarolo 04 with a stage 4 turbo lasts only 18 laps with me driving on super hard back and hards on the front at Fuji 90's. If i put a stage 3 turbo on instaed of a stage 4, (power goes donw from 1100 to 890) tire life goes fom 18 laps to 23 laps (which is the 4 laps longer than the last AI to pit!).
