Huh?
Does anyone have a method for determining proper tire pressures when changing to a different wheel/tire set up? Like for given axle weight and specific wheel & tire size & type, a tire pressure of X psi for a starting point?
I've been running 28 PSI in my 255/50 17" Nitto Invos, which feels best for driving after experimenting up and down, but now I notice some scalloping on the sipes of the outside tread of the tire. The inside tread pattern is 'coarse' enough it's hard to say if there is any wear pattern developing there. My alignment is good, 0* static camber & 3/16" total toe in. The car handles very well now on the street.
I read somewhere for tires of similar aspect ratio as mine "Vehicle weight divided by 100 plus 2 PSI" but that would put me at 38 PSI. That can't be right.
I know the proper way is with temperature readings & road tests, but I'm not really into getting into that unless I need to. But somewhere there should be a general rule of thumb.
Anybody have any input?
