The Auto-Trac Self Tightening Traction Chain is a high impact, self-tightening ratchet system that ensures a snug fit and eliminates the need to stop and retighten the chains after installation. The split outside chain with two ratchet connectors allow easy installation without moving the vehicle.
The Peerless tire chains have self-tightening ratchets. Chain installation is quick since you don't have to roll the tires over the chains. Once hooked up, the self-tightening ratchets allow you to just drive off - no need to stop and re-tighten, a feature that you appreciate when it's cold and blowing snow. Taking them off is a bit harder since you do have to roll the tires to get the chain from under the tire.
The self-tightening ratchets are plastic so longevity comes into question. I called the company and asked about that, and the rep told me he knew of some that were still working fine after 3 or 4 years. I was hoping to hear something like 10-12 years.
The chains themselves are not very beefy (but that allows the cost to be considerably lower) so again we'll have to wait and see if and for how long they hold up. The rep recommended using them only on snow-covered roads.
I bought these for my new 2023 chevy 1500. I did not want the old heavy chains i had for my 2500 hd tried them on at home in driveway went on Easly if you remember to pull out the cables from the tensioners first.
