front tires

Well any tires that will fit the 10 inch rim will work...I wouldn't go too small cuz you will lose ground clearance and the bigger tires also eat up more of the bumps so a smaller tire will ride rougher.
 
i run 20x6-10 kenda klax mxf's, they hook up great, they also are smal light and 4-ply, they are nice looking too! they look awesome with 18 inchers in the back, kinda racey looking.
