The mfg specs for tire pressure for my car a 99 C290 is 28PSI front and 32PSI rear. I read a long time ago, that increasing tire pressure in the front, as compared to the rear will induce oversteer and decreasing tire pressure in the front as compared to the rear will induce understeer. What the real story.
To me it would make more sense to increase the tire pressure in the front compared to the rear of the car because of the additional weight the car is carrying in the front, IE, engine transmission etc. :confused:
