I was doing a little 4 wheeling this weekend from Marble CO to Crystal CO and back. I was going to go to Crested Butte, but a tour guide was talking to me, and suggested that my tires were not the best for that kind of trip. He suggested light truck tires. I have Big O 'Big Foot' tires on it now, with about 4/32 tread. I am getting some used aluminium wheels and going to put new tires on them. What are your feelings on this? Thanks for any input.
