I wanted to buy some snow chains for my 4x4 in case I needed them. Then the sales person said check you manual to make sure can use. I said what good is a truck you cant put chains on . Big as light the stock tires are LT265/70 r17 and it says not to use snow cahins. I think Chevy should not be allowed to sell a truck ,that you cant put chains on. F***en Government motors. Trying to find out if cables will work or what will? Interesting point its a4x4 what if state troopers say need chains.
