Exceeding your vehicle's towing capacity could cause a significant amount of damage to your vehicle. Towing by itself puts a degree of strain on your truck, car, or SUV's mechanical systems, and these systems are only rated to handle a certain amount of weight before they could potentially fail. The tires can wear out quickly as well as overheat. This leads to expensive tire failure and the possibility of a dangerous blowout. Extra strain means the engine is also working harder to make the vehicle move.
