cold weather?

i was on my way home tonight on a road i have traveled down alot pretty smooth for the most part well any way i was riding real low and noticed my ride was a little rougher than normal its just now getting cold and i was wondering if maybe the cold weather maybe made the bags stiffer? any thoughts on this not real conserned just wondering thanks guys.

bump

my truck is only static, but it rides real rough now that its about 30 degrees everyday, oh well its a minitruck

I have noticed the same thing i think you are exactly right,does it seem to lift slower as well

bags are made out of a rubber material when rubber becomes colder or even "frozen" it looses all of its kinetic energy(elasticity or movement) and instead has more potential energy ( confined movement or less elasticity) that might have a roll in it (did a science project bout it in 8th grade)also you may want to look into that fluid big rigs use in their air brakes so your valves dont freeze up from moisture in ur air system

nah it raise just aboutn the same havent noticed a big change im in the south part of texas close to the gulf so freezes are pretty rare its snowed like 2 my whole life and im 21 the snow clears up within a few hours so i think im ok on the valves but im really glad yall took the time out and read and answer my question thanks guys
