Since new, my 2000 I30 has felt fine on level roads (no drifting, no pull), but on the usual roads I drive (local with a crown in the center) it would feel vaguely unsettled
beacuse of the crown. So, I added 2 psi of air to the right front and rear tires (Right side only) and like magic the car has a much more settled feel! Crazy! Anyone else ever do this?

 

Actually.. a good alignment shop will set up your suspension to compensate for the crown in the road. Personally I would rather have the tire pressures even to keep the car predictable.
