It doesn't just plague middle-aged men. Tire tread wears away over time and should have a minimum of 1.6 mm depth. Fortunately, this is an easy thing to check: Use a tread depth gauge for measurement to get the most accurate reading.
Uneven Tread Wear
Many factors can contribute to tire tread looking uneven, such as wear on one side of the tread. Improper inflation, problems with a car's suspension and misaligned wheels are a few of these factors. Flat spots may indicate a problem with the tire; have it checked by a tire service professional as soon as possible.
Tires with sidewalls that look cracked, split, cut, or sliced may have been damaged by road hazards, underinflation, overloading or abrasion from curbs. The rubber may also have been damaged by environmental factors like excessive exposure to heat or ozone. When this happens, your tires may be susceptible to failure. It is highly recommended to have them checked by a tire service professional.
Bulges and Blisters
If there is an unusual bump or blister anywhere on a tire, replace it as soon as possible. Bubbles like this are signs of damage within the tire structure that could lead to its failure.
A vibration problem could be caused by any number of mechanical ailments, including misaligned wheels or a bent rim, but it could also signal tyre damage. If you feel a vibration or hear unusual noises, have it inspected by a tire service professional, and replace the tire if necessary.
Now that you've paid a little closer attention to your tires and sent your car to the shop for a tire tune-up, there's a few more things you can do to keep the ride smooth from here on out:
• Get in Line
One bad run-in with a curb or pothole can throw a car out of alignment, possibly causing tires to wear unevenly and wear out sooner than necessary. Have a mechanic check your alignment periodically to make sure you're driving the straight and narrow.
• Switch Things Around
To make sure all four tyres wear evenly and perform as designed, rotate your tires according to the vehicle manufacturer's recommendations found in your vehicle owner's manual, or every 10,000 kilometers.
Don't leave home without one. Unless you're outfitted with run-flat tires (like the revolutionary Bridgestone Run-Flat Technology Tires), carrying a spare tire can spare you a serious headache. It's important to maintain a spare just like any other tire, checking it every month for proper inflation and making sure it is in useable condition. A neglected spare can be pretty much as bad as not having one.
Your tires are the foundation of your vehicle. Keep them happy and healthy, and they'll keep you rolling along.
