Bigger A/T Tire For K3500 Dually

[Jimbo0076]

Im hunting around for a set of tires for my new to me 94 K3500 dually. It has a fairly new set of 215s on it that are tiny and make the truck look goofy cause they are so short. I was reading Special K thread about the pizza cutters on his single wheel truck but was wondering about a taller skinny tire that would go on a dually. To fat and I'd have rubbing issues between the rear tires. I honestly have no idea how tall I could go on the truck up front without having issues with tires hitting the fender flares or inner fenders. We plan on going out camping and just getting out and about in this truck but will see all truck duties and hauling a car trailer duties also so I cant get to crazy with mud terrain tread but was looking for opinions on size,type and etc.
