I go over the difference between the xr1 xr2 xr3 xr4 xr5 tires. I show the tires mounted on a rim and go over who the tire is geared to and what trail conditions the tires are geard to. I also give the displayed weights of each tire.
One would think. But xr3 is heavier and is a tougher tire which actually makes for a better rear tire. A better option is xr1 rear xr2 front or just xr3 front and rear
I run the XR3 front and rear. In my opinion, if you want faster rolling. do the XR3 2.4 front and the XR1 2.2 rear, or run the XR2 2.35 front and the XR2 2.2 rear. It is really a matter of preference and confidence in cornering.
