What is the functiion of a tie bar in tread tire?
A tie bar in a tread tire is a thin, flexible bar that is used to connect the two ends of a tire tread. It is usually made of steel or nylon and is inserted through a hole in the tread and then secured in place with a nut or bolt. The tie bar helps to keep the tread from separating from the tire carcass, which can cause a blowout.
