Square link tire chains are more durable and provide increased traction compared to twisted link snow chains.
Twisted Link Tire Chains wear the high point of the twist which is a small fraction of an inch. Straight link tire chains wear the entire length of the link which could be an inch or more.
This distributes the stress and wear of the chain.
For Traction, the square alloy tire chains uses square rod which almost equals the traction of a v bar for ice. Twisted link is round rod.
For off road conditions, square also provides additional traction since the links not nestled within each other like the twisted link. This provides more profile on the face of the tire for more traction.
We offer two types of straight link tire chains.
1. 5.5mm with cams with a hardness of 56 rockwell
2. 7.0mm without cams with a hardness of 10B21.
