What is the difference between R15 and R16 tires?
4 Answers
Tires R15 and R16 have the following differences: 1. There is a slight difference in tire width. 2. R15 tires have a relatively smaller contact area with the ground, resulting in less friction, which means better fuel efficiency and improved shock absorption. 3. R16 tires are the opposite, with more noticeable road feedback in terms of shock absorption but better handling feel. Below is a detailed introduction to the functions of car tires: 1. Support the entire weight of the vehicle, bear the load of the car, and transmit forces and moments in other directions. 2. Transmit traction and braking torque to ensure good adhesion between the wheels and the road surface, improving the car's power, braking, and off-road performance; work together with the car's suspension to mitigate impacts during driving and dampen resulting vibrations. 3. Prevent severe vibrations and early damage to car components, adapt to the vehicle's high-speed performance, reduce driving noise, and ensure safety, handling stability, comfort, and fuel economy.
I just switched from a decade-old car to a new model, and the main difference between R15 and R16 tires lies in their size. The R16 wheels are one inch larger, which looks cooler and provides a stronger sense of control when driving, making the car feel less floaty during turns. However, they can be a bit bumpy on rough roads because the sidewalls are thinner, offering less comfortable shock absorption compared to R15 tires. In terms of fuel consumption, the slightly larger wheels have higher rolling resistance, which might cause the fuel gauge to drop a tiny bit faster, averaging an extra half-liter of fuel in city driving. The cost of replacing tires is also higher, with each tire costing dozens more. If you drive an older model, it’s best not to casually switch to R16 tires to avoid affecting steering. I think sticking with the factory specifications for family cars is the most hassle-free option.
I've been into car modifications for years. R16 tires and wheels have a larger diameter than R15, which significantly improves handling, making cornering more stable and providing better grip during acceleration. However, they tend to be noisier, though you get used to it on long drives. They're more expensive, requiring replacement of both the original tires and wheels, which adds to the cost. Fuel consumption increases slightly, but performance might be better on highways. Visually, R16 wheels make the car look bigger and more youthful and sporty. Before switching, make sure your vehicle is compatible to avoid speedometer inaccuracies. Regular tire maintenance can extend their lifespan, and be careful with tire pressure adjustments.
I choose tires based on my budget. Generally, R16 tires are about 20-30 RMB more expensive per tire than R15, making them less economical. Larger wheels consume more fuel, costing an extra few dozen RMB per year if you drive 10,000 kilometers. However, there's not much difference in performance and lifespan—both can last several years with proper tire pressure. In terms of size, R16 offers better handling and stability at high speeds, while R15 provides a more comfortable ride. Don't randomly change specifications; just make sure they match your vehicle.
