Few things make drivers more anxious than a mysterious light on the dash—especially one shaped like an exclamation point inside a tire. While it can be startling, this light is designed to keep you safe, not to ruin your day. At MB Clinic in Denver we see cars come in with this exact warning, and most of the time the solution is simpler than owners expect. The exclamation mark inside a horseshoe shape (sort of like a flattened tire) is the Tire Pressure Monitoring System (TPMS) alert. It likely means that one or more tires have lost pressure and are underinflated. Newer Mercedes models will also display an outline of a car and indicate which tire is underinflated. Driving with low tire pressure can reduce fuel economy, wear out tires faster, and even lead to a blowout. Pull over when safe, visually inspect the tires, and use a pressure gauge to confirm the readings. If you’re unsure, but the tire is not flat, swing by our shop—we’ll check and inflate them prope ... read more

Firestone analyzed data from over 9 million cars serviced at its stores recently, and found that 45% of Mercedes-Benz vehicles had underinflated tires. On average, they needed to add 16 psi. Higher fuel costs are a direct result of underinflated tires, because they increase rolling resistance. Moreover, this can increase tire wear as well, resulting in in need of more frequent tire replacement. According to Firestone, all US drivers (not just Mercedes owners) overspend by almost $19 billion annually just on fuel alone. But this is only first part of bad news. Underinflated tires can also cause difficulties handling the vehicle, and can also increase the risk of blowouts. Winter driving with underinflated tires reduces road traction increasing probability of skidding and sliding. We are not aware of any study that would try to quantify these additional costs – both monetary, and health costs of potential accidents due to poor handling and tire blowouts. So to minimize the risk ... read more
