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.
