I ran 20" 9 paddle haulers on my stock (no porting) cylinder 250R with K&N, Delta-V-Force reeds, 38mm airstryker, Paul Turner Midrange pipe, and a CR headgasket.

If your motor is "ported and polished", AND jetted correctly, I would think you would have no problem turning 8, or 9 paddle haulers. I wouldn't go with 10 paddle haulers though.

 

I'm running a set of 22-11-10 10 paddles on an LT500. Best sand tire available for traction. LOTS of traction. The only problem is turning...It will not turn. I would stay with the 8 paddles for anything else. A buddy is running a set of 8's on a LT250R and they work great.

 

I run the 22x11x8 9 paddle cavlar haulers and I love them.

 

I've been running 10 paddle 22 X 11 X 10 Haulers on 8" wide rims, they hooked too much, made hill climbing an exciting adventure. I just ordered a set of 8 paddle 22 X 11 X 10 Extreme haulers on 9" wide rims, I'll test them at the drag strip next weekend & at Little Sahara On the 19th. I'll let you know how they work.

Turning on Haulers is more difficult than angled paddles but I don't use as much body language on sand as I do trail riding.
