People have suggested using snow tires or installing regular tires. I don’t want to do anything that could void the warranty, so how should I proceed?
Q. In February, I traded my 2011 Mercedes wagon for a 2016 Mercedes. I purchased this new model because it had all the latest safety features, which I hope makes it a safer car to drive. The car only had 26 miles on it, and it had a four-year warranty and great financing. The problem is that it has low-profile tires. I have had to replace the right-side tires twice due to poor roads and potholes during my frequent drives to Connecticut and New York.

A. The tires are most likely 40-Series low-profile tires, which are susceptible to damage from poorly maintained roads and bumping curbs. An optional tire with a smaller wheel or a larger tire that keeps the same overall tire diameter could help. Changing all four wheels and tires, however, will be an expensive solution that may only offer a marginal improvement. As you vary from the factory recommendation, you start to re-engineer the vehicle, which can have a negative impact on overall handling. It could potentially affect the warranty, too.
