What are the two main causes of semi tire fires?

The two main causes of semi tire fires are overheating and friction. Overheating can result from under-inflated tires, excessive speed, or prolonged use, leading to a breakdown of the tire material. Friction often occurs due to improper alignment, worn brakes, or debris on the road, which can generate enough heat to ignite flammable materials. Regular maintenance and inspections can help prevent these issues.
