I usually run a General tire with some aggresive tread Helps me get around the places I have to go. I have tried michlins with a discovery that I can buy two sets for the cost of one mich and get more miles out of the cheaper sets. so I dont worry about the Better tires for my usage. I run them all to 70 psi. seems to work best for me. I will say the generals are pretty tough. Gravel is hard on tires anyway and I get in some rough road areas pulling a load so I do get some spin. and I have not experienced the Big hunks tore out on the gens like some of the other brands I have ran Mich included. Hope this helps someone.
