I've been doing searches on this same question for a while now and can't get a definitive answer. According to this list I found on discounttire.com, 235/45's should be fine. I'm going to go 245/40's... Several people on iwsti.com said this would not be an issue. Of course, my tires are brand new so I have some time to worry about it! Plus Zero 205/50-17 215/45-17 215/50-17 235/45-17 245/40-17 245/45-17
Mine are shot right now, and I have a set of 235/45/R17's in the garage right now that have about 3/4 tread on them... I need them to work...
I have an 04 and am currently riding on 235/45/17. My research shows that it's alright with no side affects.
