I've had & love the Good Year Mud Runners, But would DEFINATLY NOT USE THEM FOR SAND... the Interco TSL ( not vampire, but similar ) is an ultra low air pressure 4 ply ( but very soft ) tire availabe in 12.5" wide in several tire hieghts, & rim sizes... short of a specialty sand tire, this one would be tops...the newer radial tires should also be considered...I've heard of people mounting the mud tires in reverse direction to run in very soft sand ( pumps the sand under you rather than out from under you ??? ) never witnessed if it actually worked well or not... the Bear Claws should work fine, just remember that on very soft sand, the less air ( to a point ) that you run in your tires, the bigger your foot print, & the better you'll stay stay on top of the sand... Have A Good One ... WAM
