well tirerack had a great price on some blizzaks, 225-50-R17 and 225-55-R17. THe arrived the next day, and I'm afraid the 55's wont fit b/c on the rear of my tire, it shows 35's. But on tireracks site and talking with 2 guys over there, they said they will fit. I have a stock 2003 350z touring btw.

thanks

 

ok nevermind, the guy explained to me that they will fit perfectly. I don't know much about winter tire sizes. So all good to go. Sorry, thanks.

 

itll fit but might look weird.

stock is 235/50/17 which is 117.5 mm sidewall
225/55 has a 123.75. So your overall diameter will be 12.5mm taller ~ .5inch

 

It will look fine, very common setup to run for winter.

Good setup for snows and winter driving.
