I live in So California and have some desert land where we like to go camping and drive Jeeps and motorcycles in the desert. Because of COVID, we thought it would be fun to have our own camp area instead of camping in public areas. Well, we have this property that has a slight slope and deep sand. We bought this tractor to help establish a driveway and level pads for our RV and trailers. It has worn out tires and can barely get out of its own way. I am planning to try water filling the tires to see if that helps. Maybe take off the FEL might help too. Any suggestions for what type of good sand tires (9.5 X 24 I think)? Or any other tips? Thanks.
