k well i just ordered a set of pacer wheels (draglite copies) and there 15x10, and tires are 26x11.5x15, i put them on but the back part of the rim that has the lug holes touches the drum brake, is that bad? theres an insane amount of clearance for a 10" wheel, like more then there should be i think, heres some pics whats wrong? or may be im just dumb and its ok if the wheels touches the drum 
do i need some kind of spacer?
