In politics, we talk a lot about engines, batteries, gasoline, and electric vehicles, but we talk much less about tires. Yet a tire directly influences a vehicle’s fuel consumption, the range of an electric model, safety in the rain, and even the amount of energy needed to drive. It is therefore not surprising that California is now looking at replacement tires through its new program.
The goal of the American state government is to make sure that a tire sold as a replacement is, on average, at least as efficient as the tire originally installed on a new vehicle. On paper, that seems fairly logical to me. Less rolling resistance means less wasted energy. For a gasoline vehicle, that can reduce fuel consumption. For an electric vehicle, it can help improve range. However, is that enough to turn it into law?
The Energy-Efficient Tire, Yes, but Not at Any Cost
The problem is that a tire never has just one function. It has to drive efficiently and maintain grip, but it also has to brake well in the rain, last a long time, remain comfortable, resist impacts, and suit our climate. In Canada, that last point is even more important. Our roads are often heavily damaged, our winters are especially demanding, and SUVs are everywhere.
That is why any eventual regulation, even if it could one day make sense to implement, would have to remain careful. A highly efficient tire that wears out too quickly is not automatically progress. If it has to be replaced more often, part of the environmental gain is lost. The same goes if the tire gives drivers fewer choices or is poorly suited to certain uses, such as towing, gravel roads, or winter driving.
Of course, that does not mean efficiency should be ignored. On the contrary, in my view, it would be useful to help consumers compare tires more easily. We could imagine, for example, clearer labeling that shows rolling resistance, wet-road grip, noise, and durability. A standardized system, almost like a nutrition facts label, could help the average consumer make a better choice.
What the California program shows us is that tires, too, are increasingly becoming environmental objects. That is probably a good thing, but even I, rather environmentally minded at heart, have to face reality. The best tire will never be only the one that rolls with the least resistance, but the one that finds the right balance between durability, performance, and savings.
