l1tech is correct about the Michelin tires having a problem with Radial Runout (pulling)
I experience similar problems with my 1990 Honda Accord after I put about 20K miles on the original Michelin tires, dispite rotating the tires every 5K-6K miles.
I think part of the problem was that I went to different places to get the tires rotated and never told them how I wanted them rotated. I then decided on a rotation pattern as l1tech described crossing fronts to the rear and bringing the rears straight up on the same side, and that made a big improvement in tire wear and pulling.
I also got a bad wheel alignment on my Honda at one shop and they rechecked it and said it was in factory specs??? I then went to the Honda dealer and they did a perfect alignment? I went back to the other shop and they gave me my money back...and they also called theHonda dealership to get an explaination as to what was wrong with their alignment. I was never told what was wrong, but the manager of the shop said the guy that did my alignment was new and this was not the first complaint.......so I suspect he did not stay there long..:grin:
What was odd is that the printout from the first shop said everything was perfect??? My guess is that the guy set up the machine wrong?
