Does changing to AT tires affect an SUV?
2 Answers
Changing to AT tires does affect an SUV, with noticeable impacts such as increased fuel consumption, longer braking distance, and significantly slower acceleration. Additional details are as follows: 1. Noticeable increase in fuel consumption: Each AT100 tire is approximately 5kg heavier than a city tire of the same size, leading to a significant rise in fuel consumption. 2. Longer braking distance: Initially, drivers may find it hard to adapt, feeling that the vehicle doesn't brake as effectively as before, requiring deeper pedal pressure. The primary reason is the increased tire weight, which raises the rotational inertia of the tires. 3. Significantly slower acceleration: The substantial increase in tire weight adds to the axle load, weakening the vehicle's acceleration capability and making acceleration noticeably slower.
I think switching to AT tires on an SUV does have some impact on the vehicle, especially based on my driving experience. AT tires are designed for off-road use, with deeper and more aggressive tread patterns. The most noticeable change after switching is the significant increase in noise during highway driving, which can even affect conversations inside the car. Fuel consumption also rises because the tires have greater rolling resistance, potentially adding one or two extra liters per 100 km on the highway. In terms of handling, steering feels less responsive compared to the original tires, making the vehicle less agile. However, traction improves on muddy or gravel roads, and anti-slip performance is better. That said, tire wear accelerates, shortening their lifespan, so frequent checks on tire pressure and tread depth are necessary. I recommend switching only when off-roading is truly needed, such as frequent trips to mountainous or remote areas, and avoiding the hassle for daily commutes.
