If your tire is under-inflated by as little as 6 psi:

• Uneven tire wear
• 5% reduction in MPGs
• Tire wear is accelerated by as much as 25%
• Tire failure or Blow out

Tire pressure rises or lowers itself by 1Psi for every 10 degrees Fahrenheit.

You Should always set your tire pressure in the morning so they will not lose pressure as the day heats up. Some days the temperature can easily change up to 50 degrees and then you can lose as much as 5psi of air pressure…

The best place to find the proper inflation is in the owners manual. NOT on what is written on the sidewall of the tire that is just the min and max of what the tire can be set at.

How can you tell if your tire is at 3/32nds?

Well most tires have wear indicators. Which are horizontal rubber strips that are recessed in the tread. When these bars become even with the tread you tread depth is 3/32nds.

What kind of tire should I buy?

Well this is tricky new tires come out very rapidly so even if I recommended a tire it would be out of date in a month. But buy a tire depending on your climate makes the most sense. If you live in the far north east buy a winter tire and change it over to a summer tire in the summer. DO NOT run winter tires in the summer they will wear out way to fast.

The best place to find a good tire and get great savings is Tire Rack. They will deliver the tires to you or you can have them deliver the tires to a local tire installer.

Sometimes the installer or tire shop will try to sell you an alignment. You should get an alignment ONLY if your tires prematurely wear out.
