wow...someone actually use nitrogen...haha, i told poeple about that using in your car tires, and they don't believe me that it will help, finally someone who knows what they're talking about.

 

my bike is super light i typically run sand and trials, ill run 4.5 up front, and 5 in the rear itp blackwaters

 

i still cant get over the fact thal lowes hardware sells a co2 (painball cylinder) regulator kit for air tools...boy is that an accident waiting to happen..a little liquid past the regulator and suddenly your shooting nails with up to about 600 lbs instead of 90

 

hopefully they back bleed....i haven't tried one yet

 

umm...600? i think the most hoses for the tools would blow before that :-)

LOL... A little nitrous oxide... a little heat... KABOOM!

 

4.5 in all tires, on any of my ATV tires have proven very good to me.

 

Not running ANY air in the tires is just asking to have the tires fall off the bead. If you're reading 0psi check your gauage, or get a better quality one.

Personally I don't see the advantage of using nitrogen. Atmospheric air is already 71% Nitrogen, are you guys telling me that the other 29% is going to make a measurable difference in a tire that only uses 10psi or less to begin with? It's useful for high pressure applications in heavy duty trucks but IMO a sham for low volume, low pressure applications like atv tires.

More pressure makes a tire stiffer and shrinks the contact patch. Less sidewall roll but also less traction and flotation. Lower pressures do the opposite, offering better grip and flotation while allowing the tire to flex more when faced with sideways forces.

I'm with V2 rider in pressures, we run about 5-6 psi in the 27" mudlites on the prairie. However you're using them on a sport quad, so closer to 7-8 may suit you better.

 

nitrogen molecules are bigger than oxygene molecules...the don't leak out as fast

 

I run regular 02 in my tires and as long as I dont run over anything to sharp i dont leak any air out, maybe when the tires are old then you would have a problem with that, but thats what they have SLIME for.

I run about 4.5 in the front on my wolvy and 4 in the rear.
