Does anyone know why my new snow tires have gone down about an 1/8 of an inch in a week and a half. I wasnt driving it fast, shifting hard, or peeling out. The only thing i could think of was the fact that when i bought the car it was lowered. I think they might be Eibach GroundControl Coilovers, but im not sure. Would the fact that the car is lowered have any effect on tire wear. The car is also in alignment.

 

if your camber is off (chances are it is unless you have an adjustable camber kit) - it can greatly affect tire wear + if you got good snow tires chances are its a soft compound. look at tires - you might have uneven wear on your tires do to your camber being off - look into a adj. camber kit like skunk2 or Kingmotorsport has some for the teg (more $$$ tho)

 

How are you so sure its in alignment? Sounds like your camber is off.

 

camber is a part of alignment.

 

what exactly is your wear like? is it only the inner edges? or the whole tire is wearing down? if its inner edges it might be your camber... i would get an alignment and see that your TOE angles are in spec... those can kill tires quickly if your car isnt pointing straight..
