I was originally running 32x11.5x17 inch SSR radials before going with the 305/70/17" GoodYear Wrangler MTR's and still had a problem with rubbing, untill I did all the rest I mentioned. The problem was Width as well as heighth. When turning I had a problem...till I did some serious trimming...not minor as some claim, as I had to trim quite a bit off the front and cut a butt load of metal off the backside between doors and wheels by removing cladding bending it up trimming away most metal all the way back to the bolt mounting the fender, even trimming some of the actual nut back...then pounding it with a hammer to make mounting the inner plastic paneling from wheel well farther back and cutting away cladding between wheel and metal.
Rear springs are very easy to install...so do the front right, for the time being though, better to look like the idiots in California who lift the front and not the rearend...instead of replacing the tires from being cut or destroyed by what ever rubbs, ie rivets, metal, etc... or ruining expensive cladding
