What is a commercial grade tire?
Commercial tires are designed for heavy-duty use. They are engineered to travel thousands of miles and over all types of terrain while maintaining safety, stability, and fuel efficiency. Below, learn about the seven primary parts of a commercial tire. The distinguishing feature of commercial tyres is their focus on longevity and fuel efficiency. Businesses rely on their vehicles to be on the road, making durability a top priority. Commercial tyres are engineered to withstand the high mileage and constant use typical of fleet vehicles.Commercial tires are specifically designed for commercial vehicles such as trucks, buses, vans, and delivery vehicles.

What is the 3 rule for tires?
The 3% rule establishes that replacement tires should not deviate more than 3% larger or smaller in overall diameter compared to your vehicle’s original equipment (OE) tires. This margin represents the accepted safe threshold that preserves handling characteristics and prevents drivetrain stress. The 3% rule states that when replacing tires, the new tire’s diameter should not differ from the original by more than 3%. This guideline helps maintain proper vehicle performance, safety system functionality, and speedometer accuracy.The 3% rule says that your new tire’s total outside diameter should not change by more than ±3% compared to your current tire. If the increase or decrease is bigger than 3%, you risk problems like: Tire rubbing the frame or fork. Wrong speedometer reading (for road vehicles) Handling changes.The 3% tire rule means your replacement tire should be no more than 3% taller or shorter than your original tire.
