i've got a craigslist app on my phone that constantly searches for stuff. I've got like 15 searches going on right now, for the tires i think i just had the tire size i was looking for. 315/75/16. i've also done 35, but you get along of random stuff. 16" rim and stuff like that work too. Right now for my truck i've got Ram, Cummins, Touch Screen (in both electronics and auto parts) lights,g56, nv4500, nv5600, and 315/75/16 currently searching. all in the auto parts section. I've also got it set up to search all of washington, idaho, oregon, and montana for deals. Works great, i've found many great deals on there, and some that are worth the drive to go on a couple hour drive to pick up. The 315/75/16 search is how i found the wheels and tires i'm running right now. Now i am just searching for a set of rubber closer to 80% opposed to the 40% i've got on there now.
