Will the Mercedes-Benz GLA200's abnormal tire pressure warning affect the vehicle speed?

The Mercedes-Benz GLA200's abnormal tire pressure warning will affect the vehicle speed. Tire pressure, strictly speaking, refers to the air pressure inside the tire. Hazards of excessive tire pressure: The friction and adhesion of the tire will decrease, affecting braking performance; it will cause steering wheel vibration and deviation, reducing driving comfort; it will accelerate localized wear of the tread pattern in the center of the tire, shortening the tire's lifespan; increased body vibration will indirectly affect the lifespan of other components. The tire's resistance to punctures will decrease. When encountering sharp objects such as nails or glass on the road, they can easily penetrate the tire, and impacts can cause internal cracks and bursts, leading to a blowout. Hazards of insufficient tire pressure: The friction coefficient with the road surface will increase, leading to higher fuel consumption; it will make the steering wheel heavy and prone to deviation, creating factors that are unfavorable for driving safety; it will increase the movement of various parts of the tire, causing excessive rolling and abnormal heat generation; it will reduce the functionality of the cords and rubber, leading to delamination or cord breakage, and excessive friction with the rim can cause damage to the bead area and abnormal wear.
I've been driving a Mercedes-Benz GLA200 for several years and have encountered the tire pressure warning a few times. To be honest, the speed itself doesn't change much because the engine is powerful and well-tuned. Higher or lower tire pressure might just slightly affect fuel consumption or noise levels. But the key issue is safety: if the tire pressure is too low, the tires can easily overheat or blow out. If something happens on the highway, you might have to brake hard to slow down, and of course, the speed will drop quickly. I experienced this once before—I ignored the warning, and a few days later, the tire was severely deflated. The car wobbled badly when turning, and I had to drive slowly to get it fixed. So, while the speed isn't directly affected, it can indirectly make the drive unstable and increase risks. My advice is to stop in a safe place and check the tire pressure or go to a 4S shop as soon as you see the warning. Don't wait for a small issue to become a big problem. Safety first—it also saves you some fuel costs.
