Snow Tires Question

[ChaseS4]

Just wanted to post these and ask before I bought them, but will these tires fit my stock S4 Cabrio, the only thing that is different from my current tire is the letter in the size. I don't know what that letter stands for but I just wanted to make sure so I don't have to go through the hassel of returning them if they don't fit.
Thanks for any help that is given!

Here is the link.

The fitment should be good, the letter represents the speed rating: http://www.tirerack.com/tires/tirete....jsp?techid=35

Thanks a ton, really appreciate it! Just out of curiousity, do you know if these tires will be sufficient for a heavy winter in the mountains?? I know everyone raves about the Blizzaks but I wouldn't mind saving a couple pennies if I could. The reviews that I read said they were amazing in the snow but dry conditions they were lacking, not sure what they mean, it's not like I'll slide off a dry road, is it? Thanks again!

These are in the Studless ice & snow category, which is between Winter "Performance" and Studded winters. They'll be better suited if you're driving often on snow covered roads.

Most people who drive on cold, plowed roads that only occasionally see some snowy roads while it's snowing or parking lot at work... would stay in the Winter Performance category: Blizzak LM, Dunlop Winter Sport, Michelin Pilot Aplin.

Toyo Observe Garit-KX is also another overlooked option. That is what I run and they are great, like driving on pavement when it snows. Not a lot of places to buy them online though...
