Okay Minnesota Muscle. First off, I joind the online club in 2005 and if you want any advice on how to fix something on the MM check out our forums. I adopted my 2004 MM in August 2004 right out of the showroom. It wasn't long before I noticed the inside front treads were wearing. So this was a common complaint in the early days and a club member who worked as an alignment specialist found the answer. The factory specs were dead wrong ! He put on the Forums the way the alignment should be done but I cannot for the life of me remember the name of the post so maybe another member can help you out. I printed his recommendations, took them to my mechanic who keeps them on file and I have never had an alignment or inside tread wear problem since ! That was about 150 K ago since I got only 35 K out of the original BF Goodrich tires. And speaking of tires, the rears wear prematurely down the middle of the tire. This rear tire problem was identified early on by club members as well. Some members suggested the rims aren't wide enough for the larger rear tires. So instead of the factory recommeded 35 psi I run with 32 and have 52 K on my current Goodyear P255/55/18 tires which are SUV tires. I went a size above the 245s and have been doing that for years. This is the most tread life I've had on a rear set and should get a few thousand more just from keeping the pressure a few psi down. And no, I see no change in performance or gas mileage.
