Oh yeah, and I was running some used 35x12.5 procomp M/Ts right after I did my level kit...they were so worn down they were actually 33x12.5...they only rubbed the front inner fender well so I trimmed that and used a heat gun to melt it while pushing the outward. that worked. So i think you will be just fine with out the body mount trim.
I have read in these forums that +25 certainly does...if you just do the +6 the worse that would happen in you have to get your body mounts trimmed. I'm sure there is a lot of variation by tire, so once You get them installed, if you have a body mount issue, it only happens around full lock so you can still drive. you will need an alignment, so I chose a place that does 4X4s as well so they did the alignment and cut the body mounts and welded a plate on them and painted it. The body mount mod was only $80. I can take some pics of the gap I have now, that may help you...except my tires are a little narrower.-Jerry
