i'd go for "30x9.50r15" with either "Greenway Macho's", "Greenway Chaco's" or "Colway MT's" or "Kingpin MT's" the Kingpin and Colways are the exact same tyre just different names, if you want to spend a bit more money get a set of "BF Goodridge MT's" they will last 4 times longer than the others i've mentioned....for wheels just use the ones you have...or buy a set of "8 spokes" or "modulars" both are steel and pretty cheap...
