What is the size of a 16/70-20 tire?
2 Answers
In a 16/70-20 tire, the number 16 indicates that the section width is 16 inches, and 70 represents that the aspect ratio of the tire section is 70%. The following is a detailed introduction about tires: 1. Explanation of tire model: The model and specifications of a tire are generally marked on the sidewall of the tire, and the information displayed usually includes the tire size, aspect ratio, width, etc. 2. Tire characteristics: Tires usually need to support the vehicle body, cushion external impacts, achieve contact with the road surface, and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions, and they endure various deformations, loads, forces, and high and low temperature effects during driving, so they must have high load-bearing performance, traction performance, and cushioning performance.
As an automotive repair technician, I frequently encounter questions about tire sizes like this. The notation 16/70-20 generally refers to a tire with 165mm width, a 70% aspect ratio, and fitting a 20-inch wheel rim. Let me explain in detail: The width represents the tire's cross-sectional measurement, with 165mm being a medium width suitable for SUVs or light trucks. The 70% aspect ratio means the sidewall height is 70% of the width, providing good cushioning for a more comfortable ride, especially on bumpy roads. The final number 20 indicates a 20-inch wheel diameter, which is common for urban SUVs as it enhances load capacity and high-speed stability. However, be aware that mismatching original specifications during tire replacement may cause abnormal wear or handling issues. I recommend regularly checking tire pressure (maintaining 2.2-2.5 bar) and selecting appropriate models based on vehicle weight. From my experience, larger rims can make handling heavier but improve braking performance. Ultimately, following manufacturer guidelines saves both money and hassle in the long run.
