I am looking into geting some spindle mount wheels for my banshee. I have seen the 10"x4" ones from Direct drive and just recently saw the 10"x2" from wicked atv. Is a 10x2 with 18x4 tire a good choice for sand or should I go with the 10"x4"? It's strictly a hill shooter and only ran in the sand. Anyone know of any other companies making them?
