my rear left tire pressure keeps going down to 32psi in a week from 35psi and I just noticed that it has been worn more than others by 3mm's or so. the fronts are much better while the rear back being better than the rear left and worse than the fronts. the tires are turanza er 30 and I usually run 38psi-front/35psi-back. does it sound like it is related to an alignment and/or suspension problem? your thoughts are greatly appreciated.
the car is a 2001 QC by the way @70K

perhaps a slow leak and the fact that it's running on low pressure is affecting the wear?

KorTT

yea.. might be do you think this leak would be detected by eye and soap?

spray around the bead and the valve stem.

Concur. I've had past bad luck with leaks where the bead wouldn't seat propertly on BFG tires

KorTT

thanks!! I got a closer look to the tire and saw a lot of little cracks,seems like its fading

That's weather checking.. caused mostly by UV as a tire ages its inevitable.
