Your car’s tires look a lot different than the tires used on an 18-wheeler. For one thing, a truck’s tires are reinforced with steel, which makes them sturdy enough to handle up to 80,000 pounds of truck, trailer, and cargo. Truck tires are also much larger than a typical car’s tires. These massive wheels tip the scales at over 70 pounds and can be up to 10 feet long when the tread is separated from the wheel. Semi tires are also quite costly compared to standard tires. Prices for a single new semi-truck tire range between $300 and $1,200.
To get more use out these expensive tires, many truck companies retread them, which means they remove the worn tread and apply an entirely new tread to the tire’s casing. Some retreading companies attach the new tread with cement, whereas others use a molding and curing process for retreading.
Although retreading is generally safe and very common in the industry, the replacement treads can separate from the casing, leaving a potentially dangerous strip of tire in the road. If an unsuspecting motorist strikes one, it can cause a serious accident.
