Gave the new Cooper's a workout today on some trails around us here in Dewey, AZ. Had some serious flexing goin' on and had no rubbing. Even I thought these bigger tires would rub in the extreme flexing, but we couldn't find any evidence that they did, front or rear. I had them at 40 psi.

All in all, they performed great. Great traction and bite. And that extra 1.21" made a huge difference in the clearance. Cleared several big rocks with no problem.
Check out that airborne rear tire! WOW!!!!!
