Hi, my buddy has an 04 rubicon exactly like mine with 29.5 swamp lites and the machine has no problem at all turning them in high or low and drive or es. All he had to do was put a highlifter 2" lift and a little bit of fender trimming to make em work. Thats it, No springs or nething else. Other than the lift its all stock as far as suspension and motor performance goes. They are actually very light compared to others and still handles well on the trail. He has them mounted on 12" ITP aluminum wheels just incase you were wondering.
He also had to bend the inner fender brace on the front on each side so they wouldn't hit when he turned. I'm not sure what models or sizes have and dont have the fender braces.

look in my personal gallery at the yellow stock rubicon my buddy has with bash plates, hl lift, 12" itp wheels, 29.5 swamplites, snorkeled. as far as horsepower everything is stock and i have rode this 4wheeler personally and have seen it in action in mud many different times. it has absolutely no problem turning these tires. they are light for 29.5's so therefore they dont take as much power to turn them. all we do is creek ride and mud ride and maybe the reason your foreman's dont turn bigger tires better in the mud is because they don't have a high / low transfer case. my buddy's rubicon with 29.5's is fine in high side(manual or automatic) as far as power is concerned but we mud ride in low side. regardless what size tires is on the rubicon you should definitely mud ride in low side, because high side(drive) puts too much of a strain on the tranny when in gripping situations especially if you don't have a hd clutch kit. in my personal opinion you should know depending on your riding conditions if you can turn 29.5's on your stock foreman or not. i think you will be aight especially if you plan on getting a pipe and jet kit. if you plan on riding in peanut butter mud, you need to be looking for a different tire than the swamplite like the outlaw, mudzillas, super swamper asx, vampire, e.d.l. or mud bug even.
