Test Your Tire Safety Knowledge!
You drive everyday… BUT…..
Do you know the correct PSI for your vehicle’s tires? CLICK HERE to take a quick quiz to help you determine how much you know about tire maintenance and safety.
The “What’s Your PSI?â€? campaign is designed to challenge consumers to learn the correct tire pressure ( pounds per square inch or PSI ) for their vehicle’s tires, help them to maintain proper pressure — and ultimately help everyone avoid tire failure and crashes.
In addition to making road travel safer, inflating tires to the correct PSI has other benefits as well. Motorists who “know their PSI� and maintain it can help to optimize fuel economy and tire life, saving dollars and protecting our environment in the process.

The PSI number on the sidewall of a tire is the maximum permissible pressure for that tire as determined by the tire manufacturer. Since tires are designed for use by a variety of vehicles, this number does not necessarily reflect the correct PSI for your vehicle. Always follow your vehicle manufacturer’s PSI recommendations.Drive Safely…..

Tyre sizes and what they mean.
Okay, so you look at your car and discover that it is shod with a nice, but worn set of 185-65HR13’s. Any tyre mechanic will tell you that he can replace them, and he will. You’ll cough up and drive away safe in the knowledge that he’s just put some more rubber on each corner of the car that has the same shamanic symbols on it as those he took off. So what does it all mean?
| 185 |
65 |
H |
R |
13 |
| This is the width in mm of the tyre from sidewall to sidewall when it’s unstressed and you’re looking at it head on (or top-down). This is known as the section width. |
This is the ratio of the height of the tyre sidewall, (section height), expressed as a percentage of the width. It is known as the aspect ratio. In this case, 65% of 185mm is 120.25mm - the section height. |
This is the speed rating of the tyre. |
This tells you that the tyre is a radial construction. Check out tyre construction if you want to know what that means. |
This is the diameter in inches of the rim of the wheel that the tyre has been designed to fit on. Don’t ask me why tyre sizes mix imperial and metric measurements. They just do. Okay? |
More recently, there has been a move (especially in Europe) to adjust tyre designations to conform to DIN (Deutsche Industrie Normal). This means a slight change in the way the information is presented to the following:
