[JuMBoBeaTS]

wassup everyone... i just recently blew a tire... i have 17x7 rims with 205/40/ZR17 tires... now i blew a tire.. the rear passenger... i believe the problem is the tire is rubbing on the spring and a part of the suspension arm... i had two solutions in mind...

1. get a slightly less wide tire... i noticed that the tires stick out another .5in on each side... i was thinking the slightly less wide tire will not rub on the suspension parts anymore...

2. wheel spacers...

here are my questions...
will option 1 work? or is there no such thing??
what size wheel spacer should i use? will this completely eliminate the problem?? will i have to get longer bolts?
are there other solutions??

thanks everyone...
