I ran 33's x 10.50 BFG KM2 on my Cherokee and it went every where through the dunes at Glamis and Pismo. They worked so well the I drove in 2wd through the smaller dunes just to have more fun. But I have been going to the dunes for 12 years now so I know how to drive through the sand. The key is
airdown to 7psi, momentum, play with the throttle, and you should rarely be wide open throttle.
