i try to keep them right around 30 PSI. and no, i never noticed the steering/alignment shift all of a sudden... not while i've been driving it anyway -- no one else drives it, but i was the victim of a rear end bump and run in the parking lot at work. i guess that could have messed something up.

the bridgestone brochure i got at the shop recommends both back to front and right to left for 4 wheel dr vehicles. i was under the assumption that the isuzu dealer would know how to rotate my tires... hopefully they're doing it correctly. however, i have run into several isuzu dealership employees that know next to nothing about the vx.

i'll pose some of these questions to them wednesday when i'm up for 30k service and see what kind of answers i get.

thanks for all the feedback.
