I've received several emails in response to yesterday's tip regarding proper tire pressure and fuel economy, so I'll go into more depth regarding the issue today. There are two additional items I'd like to focus on regarding tire pressure:
- Where else you can find information regarding proper tire pressure
- What happens if you OVER inflate your tires
In addition to being able to find the proper tire pressure for your vehicle in the owners' manual or on the inside of the driver's door, you may also be able to find the proper tire pressure on the actual tire itself.
If you check both the owners' manual and the tire, you may notice that each recommends a different tire pressure, although that may not always be the case. If there is a difference, it should be pretty small.
The reason for the difference is because the tire pressure given in the owners' manual is meant for giving the car the smoothest ride, while the pressure listed on the tire is meant to reduce wear on the tire and maximize its life.
Ultimately, which one you choose will probably just come down to personal preference, and shouldn't really make much of a difference regarding your fuel economy.
Now that you're making sure that you don't have under inflated tires, you also should be aware of the problems presented by over inflated tires. Some things that can happen if you have over inflated tires include:
- Faster wear on the tire
- Increased stopping distance and time
- Increased likelihood of a blowout
Taking the negatives of having either under or over inflated tires into account, it should become even more obvious how important it is to maintain proper tire pressure.
