Summer is finally here! Even if you are not planning on taking a nice long summer road trip, your tires might need a little extra attention. The air warms up outside has an affect on the air inside your tires. Take a few minutes to check our tires to make sure they are as ready for summer as you are. 

Rule of 10

There is a rule of thumb that for every 10 degrees Fahrenheit change in air temperature your tire pressure will change by about 2%. This means that most standard pressure tires which are typically inflated to 30-50 psi will change by 1 psi. If the last time you checked your tire pressure was in the middle of winter the change in your tire pressure could be off by around 5 psi. This loss is enough to affect car handling, traction, and gas milage. 

When to Check

To avoid having under or over inflated tires, try to check your tire pressure at least once a month and before going on long trips. Also check the tire pressure in your tires if the outside temperature has changed dramatically. You can find information on your tires on the inside of the driver’s door. There is a handy chart that lists the maximum and ideal tire pressure for each of your tires. It is a good idea to keep a reliable pressure gauge in your glove compartment. Tire pressure gauges are cheap and small, you can find them in any local car shop or gas station. Most of the time the tire pressure gauges at gas stations air pumps is inaccurate.

Beyond Tire Pressure 

While you are checking your tire pressure, go ahead and check the condition of your tire tread. The minimum acceptable tread depth is 3/32 inch which is about the distance from the edge of a penny to the top of Abraham Lincoln’s head. If you tire tread is reaching the minimum, start looking at purchasing new tires. You do not want to be stranded on the side of the road with a  blown out tire. Notice if the tread wear is even or if there are areas of uneven wear. A tire may wear unevenly around the edge which means you should take your car in to get an wheel alignment. If you find lumps in the tread it could also mean your car is not balanced correctly.
