It's important to maintain the correct inflation pressure in your tires as under-inflation or over-inflation may lead to a tire failure. The correct inflation pressure of your tires is specified by the vehicle manufacturer and is typically shown on the vehicle door ledge or in the owner’s manual.

Tires may lose air over time due to the permeability of rubber so it is important to check your tire pressure regularly, at least once a month including the spare. Ensure to check the pressure when the tires are cold (i.e. have not been driven on).

Method 1 Examining the Treadwear Indicator Bar

1. Examine your tire to locate the treadwear indicator bars molded into the tread grooves. These "bars" are located at the bottom of tread grooves in various locations all over your tire, and can help you visibly determine whether your tire tread is low.

2. Check to see whether the treadwear bars are flush with the adjacent ribs. If so, this means your tire tread measures in at two thirty-second of an inch, and the tire should be replaced.

Method 2 Using a Tread Depth Gauge

1. Purchase a tire tread depth gauge from any auto parts store.

2. Place the end of the probe into any tread groove on your tire.

3. Push down on the base of the gauge until the shoulders of the device lie flat against the tread block.

4. Grab the barrel of the gauge and carefully remove the device from the groove without touching the probe.

5. Make note of the tread depth reading.

6. Repeat steps #2 through #5 on various parts of the tire. This allows you to find out whether any grooves in your tire measure higher than two thirty-second of an inch, and whether your tire needs replacing.

Do not overload your vehicle. Overloading creates excessive stress leading to heat generation and can eventually lead to a tire failure. Please check the tire placard or vehicle owner’s manual for the maximum recommended load for your vehicle.

Before you can attempt to fix a flat tire, you'll need to find the source of the leak.

1.Examine the Tire for the Source of the Leak. First, check to see if you find a screw, nail or other kinds of debris sticking out of the tire. If not, finding the source of the leak can be a little bit difficult - but we have a trick that will help make this easy.

2.Use Leak Detection Liquid. Fill a squirt bottle with a vegetable base soap and water solution or tire manufacturer approved leak detector liquid.

3.Inflate and Spray the Tire. Inflate the tire and then spray the entire tire with your bottle full of cleaner.

4.Identify the Puncture. As the cleaner runs down the tread of the tire you should notice a small volcano-like eruption of bubbles right where your puncture lies.
