Default Question about winter tire size

I had an chance to get an amazing deal on some winter tires. Basically brand new Blizzaks for real cheap. Problem was the tire size. Will a 225/55R/17 be okay on our stock BBS?

According to tirerack.com Blizzaks come in either 50R or 55R.

Well, I've seen winters with a 225/50/17 on the stockers and it was perfectly fine. I wouldn't think that an extra 5mm(i think it's mm) will make that much of a diff.

Its percent of tread width..so its 5% of 225, and then double that since you hav 2 sidewalls (one on either side of the wheel)

sidewalls will flex more around the corners due to them being taller, don't know if it will be noticable or not.

good luck

WS-50's are okay if you see A LOT of snow, but they may be too much of a "winter" winter tire for you. The tread rubber is quite soft, downright squirmy on dry roads. And the sidewalls quite flexible. Higher sidewalls will flex even more. Speaking for myself, I'd stick with H-rated or V-rated winter tires unless I lived where there is snow on the roads most of the time.
