I have an 1985 truck with a stock engine and 4.88 gears. I am running some 33x9.5 all terain tires and would like to get more aggresive treads. I was told that I would not be able to go up to 35x12.5 without getting 5.29's. Has anyone ran this setup? I will drive my truck to and from the trail and some street use so I still need some manners. I was also told that Interco tires are very heavy and would not be a good fit for my 22R. Thanks for any help.
