it is NOT just about OVERALL DIAMETER, but WIDTH AND OFFSET. If you try to fit wheels that are TOO WIDE with TOO LOW OF AN OFFSET you HAVE TO RUN SMALLER (i.e. NARROWER) TIRES. Just because the diameter is the same, doesn't mean "IT AUTOMATICALLY FITS". You are looking at things ass backwards.
You haven't even told us if you have a sedan or a wagon, because that changes things A LOT. seriously. stop ****in posting and start reading. if its too far over your head, maybe you should take the hint that aggressive fitments are NOT for you.
you should stick to 17x8 +42-48 because its a retard proof fitment. You need it.
