Okay, so here is the deal. I have a set of Sand Skate II paddles that came with the bike (87 Warrior) when I bought it. They are about half warn so I decided to go and get a new set of paddles. Went in and decided on the Sand Sharks. They have a used parts shop at the same place so I took a little look over there. They had a brand new "used" pair of Sand Sharks on a set of stock wheels for less than it would have cost me to buy and mount the new ones. The only difference is that the paddles I have are 21/12.0-10 and the ones that I bought "used" are 20/11.0-9. The question I have is, are there any pro's or con's to the smaller diameter tire, 21 vs. 20? And are there really any pro's or con's to different wheel size, 10 vs. 9? Thanks for the info..

You'll have more bottom end and less top end. The bigger the tire the better it is for top speed. The smaller tire is good for low end speed (quickness)

Pro's outweigh any con's on a Warrior with that tire. Smaller tire, less weight, easier to turn with smaller hp bike. No effect on climbing. I think those are a better bet than your old tires.

Also, what the other guy said too!

THE ONLY PROBLEMS I CAN SEE IS THAT THE BIKE WILL BE SPINNING HIGHER RPMS AND THE SHARKS ARE SMALLER CUT, SO THEY DONT DIG AS WELL AS THE SKATES. ON A BIKE WITH THE TORQUE OF A FOUR STROKE, YOU WANT A BIGGER BITE SO YOU CAN TRANSFER THAT TORQUE TO THE GROUND.

I HAD SKATES ON MY WARRIOR, AND THEY WE THE BEST I HAD RUN.
