Need 330i Staggered tire pressure advice
The rims and tires are all new (been running 1000km). Since day-1 after I replaced the stock suspension with PSS9, a problem bothered me was the shaking dampening even the car is in slow motion. The dampening was even worse before I set the shocks to higher stiffness. Until this morning, I checked the tires pressure and discovered the front left is 29.5 and front right is 32 !!! ( rears are all 30 ). So, I immediately set them all to 29.5 and leave the rear as 30.
Believe or not, all the dampening , shaking issues bothered me was gone! My question is , why the difference of front tires 29.5 and 32 has such significant effect of the car's balance and ride comfort ? I have 19" 235 , 265 staggered and the body dropped. I want to set the pressure to 32/34 , I guess this is the recommended setting of 330i for 225/255 with max. 4 persons. Please advise
