Purchased new 2017 Colorado. Have been trying to get snow tires. Called a bunch of shops, looking for Micheline lAttitude x ice 2 or Bridgestone blizzard dm-v2. Everyone says out of stock, or they aren’t made In my size. I have 255/65 17 on now. Shops have suggested some other tires, or putting a different size tire on my rims. Or buying new rims, which isn’t an option after big down payment on new truck. But I do want the best tires for icy road conditions here in Fort McMurray Alberta. Any suggestions would be appreciated!
