Oh yeah, its a 205/40's....anyhow i changed to a pair of goodyear f1 gsd3 205/40 r17. much better than the sime i had earlier.CaptainEVO said:I'm using 205/40R17's. Guess what, it rubs at the arches on any uneven road surfaces when travelling at cruising speeds. I still think you can use those tires but you need to mod the arch area. Good luck. BTW, why dont you use 215/40's?
