I can't figure out how this front tire on our car wore like this, it is only about 1 inch wide strip on the inside edge. I have always kept the tires properly inflated. This tire has make a noise from the first day we put it on, the tire store said nothing was wrong with it. Any suggestions?

By the way, the tire on the passenger side front tire is staring to waer like this one also, it just isn't as bad.

ukrkoz I didn't get the print out, sorry.

I didn't think they still made nylon tires. How would I know which the tires are? The old tires were made 2013. I got Cooper tires but don't know which one, I will look tomorrow and see what they are. I will also look to see if I see and arrow on the tires.

Ahh, what a miss... i was curious.

Fabric/Steel Cord Preparation
Because tires have to carry heavy loads, steel and fabric cords are used in the construction to reinforce the rubber compound and provide strength. Among those materials suitable for the tire application: cotton, rayon, polyester, steel, fiberglass, and aramid.
Fabric cord
Fabric cord quality is based on its strength, stretch, shrinkage, and elasticity. The yarn used is first twisted, and then two or more spools of yarn are twisted into a cord. Before shipping the cord to the tire factory, the manufacturer pre-treats the cord and applies an adhesive to promote good bonding with the rubber. The temperature, humidity, and tension control are critical before the fabric cords are calendered with rubber compound. For this reason, fabric cord is kept in a temperature-and-humidity-controlled room once it arrives at the factory.

Steel cord
Steel wire cord quality is based on tensile strength, elongation, and stiffness. It is manufactured from steel rod with high carbon content; and while the steel wires used have different configurations, all are brass-coated strands twisted together into cords. If the wire is used in a multi-ply tire rather than a belted tire, the fatigue performance will be important. If used in belted tires, then stiffness is of primary concern. Since the steel wire is brass coated, storage conditions are important to maintain the steel wire to rubber bonding properties. Therefore, the steel wires are also kept in a temperature and humidity controlled room once they arrive at the factory.
