Hey doubleadesign,
Here's my personal run down on tires. For winter and fall I run a konig NRN 16X8 rim with Mickey Thompson Baja Belted 32X11.5 tires. Spring I run American Racing HYPE 20X8.5 rim with Hankook Ventus 275/55 R20 and for summer I run the Diablo Macho SP6 which is a rim with a spinner with Pirelli
Pzero Rosso Asimmetrico 265/35 R22. Hope this help. I had to do some fender trimming in order to get the 32 and 275 to fit without rubbing but the 265 don't run and are just a little bigger then stock. I've been where you are so I hope this helps. If you go through some of any members picture galleries you'll be able to see and get an idea of what fits, looks good and decide.
