For a little while, I was running the 3-spoke alloy wheels from a '96 Tracker on my '03. The back of the spokes barely -- and I mean BARELY (like, by about a credit card's thickness, maybe less!) -- cleared the brake calipers on the fronts.
I really like the look of the ZR-2 wheels if you can get ahold of a set, and upgrading to 225 (no rubbing) or 235 (only slight rubbing on frame at full lock) tires will fill out the wells nicely. Dig through the readers' rides posts on this site and see what folks are doing.
