No, I don't chain up. For one thing, I live in California. 4 years of drought and a snow pack this year of 4% of normal. I do go to the snow, but I have 4 wheel drive and only go when the highways are R2 conditions. My truck isn't stock or else the 265's would have rubbed on the front.
I also have a Subaru Forester when headed into snow country and not needing to take a camper.
Buzz; yup! I just couldn't ignore both my load and tire ratings after I blew it and weighed my truck last year. Ha! Also, I couldn't ignore what happened to you since we live in the same general area and drive the same highways.
