The dirt hogs work fine on the front and rear. I ran them on my xxx-nt when I had it. They seemed lighter than losi's stock tires too. But your running associated, so can't compare there. I also tried pro-line mashers on the rear of my xxx-nt, but they had a lot of rotational mass to them and caused bits to break frequently when I didn't land just right due to the extra leverage. Would have faired better if RPM made arms for that rig...
I've tried pro-line gladiators on my jato and they did ok when new, but as they wore a bit, they didn't hook up at all in dirt and caused a lot of wheel spin in grass.
Now I run 17mm buggy wheels/tires. Road rage for pavement only bashing, badlands for all off road (grass/dirt only) and OFNA blazer stadium tires for in/out of pavement.
