Proper Tire Pressure

In the past, we’ve talked about how tires are the most important safety feature on your Mercedes-Benz and why you should rotate them regularly – and replace them accordingly. We know it can be easy to overlook your vehicle’s tires. After all, they’re something we don’t really pay attention to until we’re forced to think about them. However, did you know that one of the easiest pieces of car maintenance you can do is to keep your tires properly inflated?

According to a recent article by J.D. Power, most tire damage and wear is caused by driving on improperly inflated tires, so they suggest checking your tire pressure monthly. Most Mercedes-Benz tires are equipped with Tire Pressure Monitoring Sensors (TPMS), which will give you a visual dashboard alert if one or more of your tires are under or overinflated. 
Proper tire inflation is key to keeping your vehicle safe. As we’ve mentioned in previous posts, your tires are what connects your Mercedes-Benz to the road. This connection to the road is what signals all of the other safety features to function properly, whether it’s Attention Assist letting you know that it might be time for a break or Adaptive Braking, which helps you apply enough brake pressure so you can stop with enough time to avoid or minimize a potential accident.  Tire inflation also has an effect on your vehicle’s fuel economy, as well as the way your tires wear, so you’ll have to replace them sooner than you would if you kept them inflated properly. While your Mercedes-Benz is equipped with lots of incredible safety features, none of them will work properly if you don't have the right amount of air in your tires - including your brake system. 
Regularly keeping your tires underinflated reduces the life of your tire because there is literally more rubber meeting the road. Under-inflated tires also have a negative impact on your fuel efficiency; since under-inflated tires are softer, it takes more engine power to turn them. If you’ve ever driven with a flat tire, then you know from experience that you’ll also have a bumpier, more uncomfortable ride, and it will be harder to keep your vehicle under control. 

Meanwhile, overinflated tires can result in similar issues. When there’s too much air in your air tires, there are still vehicle control issues – this time, because there is not enough rubber making contact with the road. You may find that your Mercedes-Benz feels a little “bouncier” than it otherwise might. This also puts your tire in more danger if you hit a pothole or other road debris, as you’re more likely to experience tire damage or a tire blowout due to excessive air pressure (like popping a balloon). Of course, an explosive flat tire also results in further control issues. 

Tires that are properly inflated will certainly reduce the potential for a flat, but will also allow your Mercedes-Benz to function at its optimum level, from everyday driving to making emergency maneuvers. It will also allow you to maximize your fuel efficiency, so you won’t need to stop at the gas station as frequently. You can find the correct tire pressure for your vehicle in your owner’s manual or by looking inside the fuel door. 

Your Mercedes-Benz is equipped with a tire pressure monitoring system that will automatically alert you if the tire pressure is low, but most gas stations have air hoses that will allow you to check your tire pressure and adjust the air up or down accordingly. The service teams at all three of our Mercedes-Benz dealerships are always available to help with your needs, too, whether it’s tire related or something else completely.
