With your circumstance, why even order chains? Basically, you are making a bet. On your return, long before you get to the point you need chains, check the weather reports. You may not need chains. If you do, buy them in route. Everything considered, I doubt they would cost much more. Consider, a truck you probably paid several thousand for your truck, and several thousand for the TC. Now you are going to choke up paying $20 to $30 more for chains? I see Les Swab chains for less than $100, how much do you think you will save?
