After much debate I have decided that I am going to put snow tires on my 2011 Mustang. I ended up going with the black 19" Ford track pack wheels with Blizzak tires.

Trust me, I am not going to be driving it when the snow flies, but it will be nice to take it out on a clear day when. The tires on there now are strickly summer and I have the Brembo break package.

My question is that I have found a set of barely used Blizzaks that are 245-40-R19. My current tires are 255-40-R19. I know these tires will fit the rim, but other than the load size is there any real difference between the two sizes?

 

I always seem to get hang up on winter tires question for Mustang. On one hand, I can see the benefits of winter tires when there is snow present, but would I want to sacrifice dry tractiction on cold but clear roadways at higher speeds? I would like narrower tires but the stock rims are too wide...
