I looked up the specs on the bfg tire, there is a 6 lb difference between a 32-11.5-15 and a 33-12.50-15. You can get the weight back by using a 33-10-50-15. You'd still get the height, but it's not as wide.
Also it appears the 33 RVT is 1 lb lighter than the same size bfg AT
What tire pressure are you running?????
