Well, after talking to our DOT contacts and seen what they run, we can get some on contract. I believe they are Pewag (sp?) brand made in USA. He is supposed to send me the contract list tomorrow. Pretty much he recommended at 4 link due to lower cost, square link 7mm with cams. That’s what they’ve been running when they have to have them. They also have a v bar/studded chain. He said they may work but are ROUGH, even off road. I did manage to talk him out of a set of 14.00-24 chains for my road grader since they have new graders with bigger tires now!
