Ever wonder what the designations stamped on your tire sidewall actually mean? We’d like to break it down for you.
Let’s take for instance, “P195/60R15 87S”. This is a full service description of a tire.
In this case, “87S” denotes a tire’s load capacity and speed rating. The higher the number, the greater the load capacity – an 87 load capacity means that tire can support 1,201 pounds. Speed ratings range from L (75 mph) through V (149 mph), and an S speed rating means the tire is good for 112 mph. W, Y, and Z-speed rated tires are available for extreme performance cars and are rated as high as 186 mph.
As for the rest of the information:
--“P” denotes Passenger Tire
--195 is the tire’s width from s ...[more]
Driving around on underinflated tires is just a bad idea all the way around. Underinflated tires increase a car’s rolling resistance, meaning a drop in fuel efficiency since it takes more energy to move the vehicle down the road.
A single tire that’s down by ten pounds of air means a 3.3 percent drop in fuel economy…multiply that by all four tires, and you can figure on giving up ten percent of your gas mileage. The added friction and rolling resistance also means more heat is generated, and heat is the enemy of the internal structure of a tire. That heat will damage a tire to the point of failure. Studies show that underinflated tires are a full 25 percent more likely to fail, and at least half of one-car accidents involve a tire problem as a factor. And still, it’s estimated ...[more]
As most drivers can contest firsthand, tires are not invincible. Composed from many separate layers of steel-encased rubber fabrics and durable materials, tires eventually wear down and can cause vehicle owners costly repairs or even replacement. Understanding what measures should be taken to properly maintain tires will both lengthen tire life and support vehicle functionality and longevity. Tire Pressure Monitoring Systems (TPMS) introduce revolutionary tire protection technology to constantly report on tire pressure in each tire for vehicle safety and sustainability.
Without assistance from a Tire Pressure Monitoring System (TPMS), tires become more susceptible to avoidable damages due to low tire pressure. In the United States, according to National Highway Tr ...[more]

Checking your cars tire pressure is very important to the performance, handling, and life of your tire. It is especially important in the summer because the heat makes the air expand causing over inflation issues leading to a blowout.
Checking tire pressure is one of the most neglected services on a car. Some people would agree when we say that checking the pressure in your tires can take a bit of time and hassle. As troublesome as it is those few minutes and that little hassle can actually save you a lot more than you think. Having your tires at the recommended pressure can save you a lot such as fuel, money and the tires themselves.
The recommended tire pressure differs from manufacturer to manufacturer and the weight and dimensions of the vehicle. If you don't know the recommended pressure of your vehicles tires there are several ways you can find out. You can ask your trusted auto mechanic, your vehicles m ...[more]
