40's on a light ass jeep and you will slide on anything that isn't siped.from my experience. i had a set and my uncle had a set of 40s on his jeep. there great if your in mud or dry payement but if a dog pees on the sidewalk you slide.
Do yourself a favor and get the radials! If ya live where it's cold the polyester belts will rattle your teeth loose (Experience). Also on pavement hold onto the steering wheel around bends as they will wander. They didn't last on my daily driver on pavement less than 7 months!!! However I never got stuck!!
:stupidhad the LTB's on my 87 for about a 10k miles then they were gone. great off road but on road they leave a lot to be desired.
Why 34's? Why not 35 or 36". You are still planning a 4 or 6" lift right. Just wondering. Any Superswamper will have soft rubber and wear like crap.
