hey, ive got a 73 blazer with 40"s mickey thompson baha belted(useless tires) on right now. im debating between 39.5 x13.5x15" IROKs, or 39.5x18.5x15" boggers. my truck is a mud bogger, and thats about it, but i drive it every day to school and back. im wondering if i should get the iroks as they would have much better handling on the road than the boggers. im wondering how they would compare for perfomance in the mud. what do you guys think? are the boggers gonna demolish the iroks in the mud?
