Why do tires matter ?

Tires are your car's only point of contact with the road—four contact patches, each roughly the size of your hand, are all that separate you from the pavement at any speed. Every braking, steering, and acceleration input passes through your tires. A tire that's worn, underinflated, or wrong for the conditions can dramatically increase stopping distances, reduce handling precision, and raise the risk of blowouts. No advanced safety system—ABS, traction control, ESC—can compensate for a fundamentally compromised tire. 

Yes, more than most drivers realize. Rolling resistance—the energy a tire expends as it deforms under load—is responsible for roughly 20–30% of a vehicle's fuel consumption. Low rolling resistance tires can improve fuel economy by several percentage points compared to standard tires. Michelin has made low rolling resistance a core design priority across its lineup. Equally important: keeping your tires properly inflated. A tire that's 20% underinflated can increase fuel consumption by 1–2%, and that adds up over a year of driving. 

Yes. Tires interact with your brakes, suspension, and steering. Worn tires increase stopping distances, making your brakes less effective. Unevenly worn or unbalanced tires create vibrations that stress suspension components. Misaligned wheels cause tires to scrub, which accelerates wear and can affect steering feel. In short, tire maintenance isn't isolated—it's central to the health of the whole vehicle.
