I hope you guys ain't running E rated tired at 40+psi.. I'd pull my hair out.
Hah. E-rated KO2s at 45psi. Aired down for off road of course, but I wouldn't have it any other way. C is too soft for the rocks—I shredded 2 tires in a single outing once—not a fun day. It's never happened again after moving up to Es.
And yeah, I feel the bumps. All of 'em.
