Ok so I'm an idiot, I bought my car with 4 of the same tires on it and the fronts were wearing a lot worse than the rear. I've got a friend that works at a junkyard and hooked me up with 2 tires i couldn't refuse so i put them on the front and about 5k later I'm realizing what i did. The tires are all 205 65's but the fronts are a different brand and are an inch smaller in circumference than the rear. I've been planning on getting 4 new winter tires in the next month or so will I be fine to drive the car how it is or should I get the snows asap? What kind of damage could it do?
