    Default 2012 Silverado 3500 Winter Tires

    My truck came with Michelin LT265/70R18 all season tires but are not winter (mountain snowflake) rated. Started looking at some local dealers for a winter tire in that size and finding them hard to locate with load range E. Les Schwab recommended a different size (LT275/65R18) for $260 each. First question is what manufacturer makes a winter tire in my stock size with load range E? Second question: If I can't find a winter tire in my stock size, would the LT275/65R18 tires provide enough clearance in my wheel wells for turning without rubbing any components? With a wider winter tire, I can see a problem with retention of rocks in the treads and throwing them into the wheel well or worse. Last question: any brand recommendations for a tire in my stock size? Thanks for any input.

    Those two tires are close to the same height. The second number in a tire size is a percentage of the first number, giving you the height of a tire. Multiply 265 by 70% and you get 185.5 millimeters. 275 X 65% (.65) is 178.75. A closer match would be a 285/65R18 which would be 185.25 mm tall.

    Go to and plug in the size you want. You will see all the brands they offer.

    The Bridgestone Dueler AT Revo 2 is a good tire. I run the Hankook Dynapro ATM RF-10 tires and get excellent mileage out of them. Tirerack doesn't carry them, but Amazon does.
