What does low rolling resistance of tires mean?
2 Answers
Tire low rolling resistance means using low-resistance rubber compounds and tread designs to reduce the rolling resistance of the tire, which can help lower fuel consumption. Content about tire low rolling resistance: Low rolling resistance tires are fuel-saving tires, generally achieved by modifying tread grooves and adding silica compounds. Low rolling resistance tires are a technological innovation driven by increasingly stringent passenger car emission standards in the EU and the US. According to the EU's 2020 passenger car emission standards, the average CO2 emissions of car manufacturers' product lines in the EU must reach 95 grams per 100 kilometers. The tread patterns, sidewalls, and rim sizes of low rolling resistance tires differ from traditional tires. These tires have a larger diameter and narrower width, but their drawbacks are also evident: reduced grip, and delayed and weaker acceleration and braking on wet surfaces—key factors in vehicle handling that significantly influence consumer choices. Function of tire low rolling resistance: Low rolling resistance tires are now a very common type of tire, often used in green, fuel-efficient models. During driving, nearly one-third of a vehicle's fuel consumption is used to overcome tire rolling resistance. Therefore, the primary benefit of choosing low rolling resistance tires is effectively reducing fuel consumption and being more environmentally friendly.
Low rolling resistance tires are the kind that have very little resistance when the car is rolling. I feel that after installing them, the car drives much more effortlessly because the friction between the tires and the road is reduced, which means the car uses less fuel. As someone who drives frequently, I noticed that after switching to these tires, my average fuel consumption dropped by about 10%, especially noticeable in city traffic—the fuel gauge drops more slowly. However, I’ve also observed that the grip of these tires can sometimes be weaker, particularly when driving fast in rainy conditions, making the car feel less stable. So, I recommend checking brand reputation when choosing tires—don’t just focus on fuel savings; safety comes first. Additionally, regularly checking tire pressure is crucial because proper inflation ensures the low rolling resistance effect works optimally.
