Why check your tread depth?

With good tire depth, your vehicle will be able to grip the road very well. This is very important especially when its wet, snowy or on a dirt road. It also helps prevent you from hydroplaning. Once the tread depth is less than ideal the tires are more likely to slip and slide making you dangerous to everyone else on the road.

When the tires are worn many other components may be worn as well. As the tires wear the rest of the vehicle slowly feels the strain more and more as the tread gets less. While tires may be a bit on the pricey side they will definitely be worth the investment.
