How to avoid breaking chain links

What's the best way to go about chaining up? After I get my chains on, I roll about 15-20 ft forward and retighten all my chains as tight as I can get them. Somehow, last winter season I still managed to snap five cross-member strands on two tire chains. I usually only wear them on heavy snow packed roads so the asphalt doesn't eat through the chains too much. Also, I keep mine on usually around 50-100 miles at most with an average speed of about 55-60 MPH. Most of my company drivers do about the same and fair better than me. They tell me I don't have them tight enough or that my chains are just too old and rusted. Any ideas?

 

Yeah, they keep telling me that I don't have them tight enough. I run LTL and they expect us to get there faster than averaging 35 MPH. I am usually out there by myself at night and going faster than 35 is comfortable for me. Again, any good methods to getting your chains tighter?

 

@joseph Got ya. Thanks. I havent had any issues running at higher speeds. Just trying to keep up with everyone else.

 

Nope. No accidents here. Aside from snapping five strands, my tires are doing fine.
