A 35x16x15 bogger on a 15x14 wheel. U can clear it with 6 inches. I recomend at least a 4.10 gear. That's the best there is in mud. The wide wheel puts more tread on the ground making it last longer on the road. U will see a lot of them with full tread on the outside and slick in the middle due to a narrow wheel. The trick to making a bogger ride good is to let it balance itself. Don't put wheel weights on them. I think. U will be surprised at how smooth they can ride. But don't waste the money if u arnt going to buy the wide wheels. U will be throwing the tires away not long after.
