I'm in need of buying tires soon, came across that i'm quoted about $1000 for a set of 4 brand new tires. But since winter is here i better just stock on some tires that are cheaper, like used. Then buy summer tires later. But i know this really good used tire place where they just have 225/45/18 in stock. Has anyone ever tried putting those in the front or back yet? How did it feel and was there any differences?
