DeniskaGS4

I have a 2000 gs4 with about 15k on it. I noticed abnormal tire wear on my front tires, so I took it to the place that did my alignment. My mechanic told me that my tire pressure was way low around 27psi and its recommended 33psi. Would such low tire pressure cause abnormal tire wear? and at what pressure do you guys have your tires? I have the stock 17” Lexus rims with Bridgestone’s

Deniska - If it was underinflated for a long period of time, the tires would be worn on both the inner & outer edges, possibly near the first grooves. If they were worn on only 1 side, then your alignment's off. Didja rotate the 17's? When I had my 17" Enkeis, I kept 33 psi in them as that the pressure that Lexus recommends for the factory 17's ( supposedly the suspension is designed for those pressures - believe the 16's require 32 psi ).
