Ever since I changed my stock rear tire's on my Raptor to 20x11x9 ITP Holeshot's, I can't do nothing but spin on every type of terrain. Before it would wheelie all over the place, now it just spins. I've tried lowering the air pressure from 7-5.5psi and still acts the same way. Is it the tire's?? I have triple rate ssd on the way with a lowering link. Will this help with traction by lowering the center of gravity? What should I do??
