I installed the winters past weekend and now the bolts on the driver side(rear) keep coming loose. I drove about 15 kms and had to tighten them(all 5) 2 times. It's especially bad on turns...Mind you I ran the same setup last winter and it was fine. The rim couldn't just have bent itself lying in the basement? Only one?
Why not the others then?
Summers were 17s-winters are 15s. I doubt that has anything to do with it since I've only put 40kms on this week.
