My tundra currently has Michelin 265 70 16's. I am considering replacing those with 245 75 16's. I live in snow country and the narrower tire might be better in the snow. I will be putting a pop up camper in the truck bed. The narrower tire has a heavier load rating. Is there a downside to a narrower tire on the Tundra? thanks - this Forum has been very helpful.
