The Bedford brand tire is a lower priced alternative to the Firestone and Denman brand tires. These are a nylon 4-ply tire. The drawback to nylon tires is that they tend to develope flat spots when they set for long periods of time. The flat spots go away quickly when you start driving the car again and the tire warms up. Nylon tires will normally wear longer than a polyester tire. Imported.
