Dude, get a set of used 17" X5 wheels from eBay, and put a set of Bridgestone Blizzaks on them.
You will spend the same amount of money for the used rims and the new Blizzaks as you will for a set of 19" snow tires. And you won't have to have the tire shop mount and dismount the snow tires from your rims, which, incedentally, will wreck your tires after a few mountings. And cost you a bunch of money

Everything I've heard about the Diamaris is they suck. Get the Blizzaks.

If you don't think I'm qualified on the subject of snow tires, look at where I live. I drive on ice and snow 6 months a year. And we don't use salt on the roads. They are just covered in packed snow and ice all the time.


Lambeau has some good pics of his X5 on Blizzaks driving through snow that he posted a few weeks ago.
