Car artist Billy F. Gibbons' (aka the guitarist from ZZ Top) Bus Ball invokes a well-deserved "Whoa, cool." Coker tire blog asks "Where's the dang tires?" Gibbons responds: "the Coker skins [wide whites, of course], are stashed in the boot! Sort of a James Bond arrangement where the tires unfold when required. By the way, the gas mileage is superb and the wind-resistance factor is greatly improved over the original design."

thanks chad!
