Paddle inflation

think of it like this. the less air you have the more paddle is on the ground. in hance the less air the more the paddle will fold.there is a thin ling between the both to much air the less paddle but the paddle will not fold as easy. just trying to help

I agree, this is a tough one and the reason you will get many different answers. I think you will get diff. results at different pressures w/different configurations. On a straight blade hauler for instance, more paddle is on the ground w/less air but more susceptable to folding over as mentioned. There is prolly a point on the low and high side that equal out in traction. On the high side, the paddles stay good and rigid possibly gaining you better traction....you see what I mean. On a staggered, still holds true, the more air the less chance of paddles folding over on you. BUT.....when you air a staggered down, you get a lot more paddle on the ground than you do a straight blade.

 

I believe then going to a different tire, say a ripper, those paddles are so stout, you may not ever gain traction on the high end because they just don't fold over....I don't know this to be true, just trying to prove a point for arguments sake. I guess my answer would be, every tire is different. You may figure out a set of rules for a straight blade hauler, but those same rules may not apply to all other configurations.

last year in my ten paddles i was running 3.5 psi. I start me 12 extremes out at 6 then work my way down depending on track conditions.

 

If this is a Drag question, I have no idea. But for duning, I run my sand sharks at 6psi. In the sand, if you run them any lower, all you do is shoot a ridiculous roost, and don't gain any traction, I have found, with my particular tires. I have found that 6lbs in the dunes is that fine line between comfort (Hard tires = rough ride) and not pissing off everyone following you. I haven't noticed them "hooking up" any better at lower pressure, but that obviously will depend on the tire!

I used to run my Haulers at 2psi and they hooked up great. But I got tired of buying tires bcause a paddle either split or flew off. I now run them at 5psi and it doesn't hook up as good, but I am not losing paddles either. The hookup doesn't bother me too much because I have quit racing, it's just the wife and I having fun in the dunes. I intend to try a set of Extremes for my next set to see how they hold up at lower pressures.

There is a certain point when you air down that you'll strat folding blades.. But that depends on the tires. The extremes can be ran at lower pressure then the haulers since the blades are thicker at the base which resists folding.. I have ran my 72ro extremes with 1.5lbs..

I have 20x10x10 8 paddle haulers and I run 3 psi in the loose sand in idaho. When I go to Oregonhe sand is a little wetter and do not need the hook up. need a little more of the wheel spin. I do notice that at 3 or a little less, the tires will actually turn on the rim

I feel with more air pressure your getting less paddle in the sand (because of how balooned they are) but because there is less paddle grabing sand it is easyer to push in the high end of the gears. When you launch the little area that is touching the sand moves the sand under it and the whole paddle then grabs.M

 

My bike is underpowered for the paddle so i think the more air makes it push it much easyer. From running 2.5 lbs to 8lbs i gained in my 60 ft and et.

 

I dont think all the paddles react the same though, even comparing haulers the tire it was built off of makes a difference.
