I want to get some winter tires for my Spec V. I want to get some base steel 15 inch rims and then get the blizzak tires. I want to do this without ignoring some concerns by changing the size of the tire. For instance, will a 15 inch rim give enough clearance to the stock rotor and calipher? I am thinking of going to a junk yard to get base (Steel) 15 inch rims from a nissan basic sentra model. Also will the 15 inch tire be able to have the same diameter (offset by having a high profile tire) as the 17 low profile tire so that my speedometer will not be wrong? If anybody has feedback on this it would be great. Everyone I have talked to has told me to purchase Blizzak's and get them from tirerack.com. All suggestions greatly appreciated. I already roughed up the bumper trying to go through winter with the stock tires, I was lucky to get away with just that. Now I have the money and time to get some good winter tires so I can make it through this winter alive.
