I wondered something similar. I have 285/75/16 tyres on and it's lifted with body cut to take the tyres. However, with a 2" lift it doesn't look like the body needs modification, when I change I will be moving to 245/75's after the wheel arches have been replaced and new front wings put on. However, I am leaving the rear modified so it will be fine for me. I would be interested to know people's thoughts on beorn's question.
