Best Tire Brands for Winter?

[just_dave]

Searching online for an all-season/winter light truck tire. Reading the online reviews isn't a big help. Coming here I know I can trust the input.

Tires will be going on a Silverado 4x4. I was thinking of going with the Cooper Discoverer X/T4 in a 265/65R18 or a 275/65R18.

Something I'm most concerned about is life of tire. I hope for the tires to last at least 3 years before showing any sign of dry rot or separation. Winter handling is second.

Any recommendations or warnings would be much appreciated.

Thank you in advance!
