Self-Tightening Ratchets – This devices will help you in two ways. One, they will make installation that bit easier, by tightening the chains through the motion of the wheel. This will also help you to keep the pressure of tire at the best level whilst the vehicle is in motion. This is important, as a chain
That is too slow and won’t give the grip you needed and is also more likely to be damaged. Premium models should comes with self-tightening ratchets and whilst you may be entice to save money with a cheaper model that lacks them when you are crouching in the snow while trying to tighten the locks with frozen hands you may remorse that decision.
Tread – We are talking about is the contact point between chain and snow,ice, and road surface. We had a number of methods on the list varies from nails to cables to traditional chains.
A traditional chain is tested tread with lots of surface area to create friction. Try to look out for models with patterns cut into the chains, they can help give a little extra traction.
Steel cables are much newer but seem to do a good job of creating lots of traction for safe driving conditions.
Clearance – Basically it will tell us to how thick the chain should be, with the thicker chains will have the higher clearance. The chain needs a clearance where it won’t hinder the movement of the tire.
