23" front (I run Holeshot HD's), 22" Rear ( I got 6 ply HD knock-off, which are pretty tough and are holding up well).. both on stock rims.

 

what "knock-off" are you running. After today's ride I'm in the market for a new rear tire. Thinking about going to 22" rather than the 20" i've been running.

 

"WD-Velocity" is the only name on them.. I picked them up used off here.. think I paid $90 shipped for the pair.. like new. They are pretty tough for sure I ride in pretty rocky (sharp rock too occasionally) ground sometimes.. I don't care about weight / traction too much for my rough desert set-up.. mostly flat / rolling hills where I ride.. I just want the ground clearance and puncture resistance.. no racing.. just trail riding / exploring etc.. The 23 / 22" combo works well, my one riding buddy has 21/19" combo and he gets stuck / hits stuff I just cruise over..

 

thanks. i'll see if i can find some. i ride desert mostly, but we ride rocky mountains occasionally. i beat the **** out of mine today with 20" on the back. not to mention the huge tear in the tire.

 

I ran Artrax MXT 20-11-9's 4plys and love them. Had a flat during practice and both motos at Redbud mx and the tire still airs up fine. (had dirt in the bead causing the flats)
