What are the effects of larger tire sizes?
1 Answers
Tire sizes that are too large will result in shorter mileage, failure to pass annual inspections, increased fuel consumption, and may lead to phenomena such as 'tire wear' or 'pulling to one side,' as well as reduced tire lifespan. Specific effects of larger tire sizes: Original tires are more in line with fuel consumption standards. Larger tires mean increased weight, leading to higher fuel consumption during driving. Mileage becomes shorter because as the tire and rim size increase, the tire's diameter and radius lengthen, increasing the circumference. This results in a reduced rotation speed and noticeable changes in the distance covered per rotation. Failure to pass annual inspections is due to Article 16, Section 1 of the 'Road Traffic Safety Law of the People's Republic of China,' which states that no unit or individual may assemble motor vehicles or alter the registered structure, construction, or characteristics of motor vehicles without authorization. Precautions for replacing car tires: When selecting tires, the specifications must match the previous tires and be identical to the other tire on the same axle, including speed rating, load index, tread pattern, brand, size, etc., to ensure safe driving. The valve stem should also be replaced because, after changing tires, the aging cycles of the new tire and valve stem differ. During the new tire's lifespan, the valve stem may develop issues that are not easily noticeable. Therefore, it is best to replace the valve stem when changing tires. Installation direction and inflation: If using original equipment tires, follow the manufacturer's installation requirements. For non-original tires, the side with the production date usually faces outward. For directional tires, align the arrow on the wheel with the car's forward direction. When inflating, fill to the maximum pressure allowed by the tire, then reduce to the manufacturer's specified standard pressure.
