I noted in a previous post that someone was told that they couldn't put 15" winter rims on thier ZX3. Unless it's an SVT that's a crock! I'm running WM-50 Blizzaks on 15" Wal Mart steel rims and there is no problem with clearance whatsoever. BTW, The Blizzaks are fantastic, much better than I anticipated. Also, I need a recommendation for a decent relatively inexpensive performance oriented summer tire.I'm thinking Proxes 4s or Kumhos on my factory 16" rims. I'm not eager to go to a bigger wheel as the roads here suck and going to a smaller profile runs a much higher risk of bent rims. Too bad though, I'd like 17s. :0(
