I just picked up my new Viking today, took the new wheels and tires with me and they mounted and installed them for free! I wound up going with 28-11-14 Zillas on all four corners and I'm so glad I did. I always thought 9s looked too skinny on the front. I was a little worried the 11s would rub in the front but no problems and really looks like the perfect size tire with no lift. Fills up those huge fender wells nicely but with no rubbing issues. My wheels were 5+2, if I did anything different I might have seen about a different offset for the fronts because they do appear to stick out a little wider than the rears, but if they were in tighter that might also cause them to rub.
