I have a Michelin on my '94 with a bad sidewall. According to the guy at the tire store, I can just put the spare on and should be fine (spare is new, tires on vehicle have about half the tread left). I have read the various post on this webpage that tend to disagree with the tire guy. If I recall, the easiest fix short of buying four new tires is to have the spare cut down to match the other three. I said something to the tire guy about this and he said that he didn't recommend that. He said that to do that they have to heat the tire and afterwards it can get hard. Once again he stated that he knew Toyota recommended 4 new tires, but that the vehicle had a dummy factor built in and that the difference in diameter of the tires shouldn't cause a problem. I am leaning towards just buying 4 new tires that match the spare and then start rotating all 5. However, I was thinking that I could keep the other 3 tires and when the new ones wear down to the same diameter I would have 2 matching sets of 4. If I go this route I'm also thinking about just picking up 4 used OEM rims. What do you guys think? Any input would be appreciated, and if anyone has any OEM rims for a '94 let me know.
