Shawn...different tires on front and back will wreak havoc on your trans and differentials...

Chopper...I don't doubt you melted the clutch with the bigger tires on...I had a similar prob on my 1/8 Hurricane...clutch still works just wore the shoes down (3 shoe clutches in the 1/8's)...we need to gear these down if we are going to truggy them and get heavier duty clutch shoes.
