Thanks for the suggestions guys. I haven't driven the truck very much lately as I have been driving my fiancees Vibe around. When I drove it the last time it was warmer(40's) and the vibration wasn't present. Though I think that there is a wheel(or 2) with the weights stacked up I'l check it when I get home. I also check psi that day and it was higher I think that I will try keeping the pressure up(35) and see if that helps things. I'll make it a priority to get the tires balanced checked because I have a wedding to go to thats a long way away.
