The air pressure does have a significant impact on the safety of your ride and the wearing of the tread on the tires. Here are a couple things you may not be aware of that will impact the life of the car tires when the pressure light stays illuminated.

If there is too much air in the car tire, the tire tends to ride only on the middle of the tread, like a balancing act. That means less tread is contacting the road, and in inclement weather, you run the risk of not being able to control your vehicle. Too little air in the tires is worse because not only is all that extra tread on the tires making it harder to control the handle the vehicle, the tread wears faster and increases the chance of a blowout.
