Do you guys think 71 fj40 axles will handle 39.5 swampers. I'm swapping mini truck knuckles on the front. I've seen some fj40's with tires that big, but wonder if I'm opening a can of worms by putting such a big tire on cruiser axles. I've done a soa and have 2" springs on the back., I think they'd clear, just don't know if they'd rub on the springs? Anybody have tires this big on their crusier? Thanks
