Tire presure's
 

Hi Guys

I got the 700 Prairie all back togther and made it out to play in the snow ...We got about a foot and a half of the white stuff , I just got the Dirt Devils mounted they go pretty well ...In that deep snow I was running under 30mph and the machine just seem to take care of business.
My question was about the tire presure , I am a where that the larger tire have more weight , don't flex as much as the stock 2ply , on hard pack they do give the machine a little steering shaking .
Right now I'm running 4psi but I was thinking of going a little lower ...any one have any sugestions ...most of my riding is under 40mph .
Thanks
Greg
