Have you been wondering lately if you need to get new tires? Tire failure is responsible for almost 10,000 crashes a year, so it's important to make sure that yours are always safe. Your tires go through a lot of wear and tear over their lifetime, and knowing the signs to look for to determine if the time has come for a new set is critical. A quick tire inspection will let you know whether you're due for new ones or not.


At Piazza Subaru, we take pride in offering some of the best new Subarus in Phoenixville, Pennsylvania, including high quality Subaru Foresters in Montgomery County. We also want our customers to be safe, so we've created a checklist to let you know if you need to change your tires.


One of the best ways to tell if you need new tires is the penny test. Simply place a penny into the tread of your tire and point Lincoln's head down. If you can see the top of his head when you look at the penny, then your tire treads are worn and shallow.


However, the Penny Test is not the final say on whether you should replace your tire or not. Nowadays, many tires also have wear bars. These indicate that your tire tread is low when the tread pattern is worn down to the bar. Most tire manufacturers also recommend changing your tires every six years from the manufacturing date of the tires.


Do you hear vibrating or thumping sounds when you're driving? If you feel like something is trying to push you out from your seat, then you can bet that your back tires are unbalanced. Tires can suffer from various factors that can negatively impact their performance. Whether it is uneven tread on your tires, improper balance between your wheel and tires, and other common issues, when you feel your tires vibrating while driving, it may be time to replace them.


Steering wheel vibration is also a good indicator that you have suspension issues. If your suspension has gotten off balance or has worn down, it can lead to a bumpy ride. If your car is not running smoothly, and you experience any of these issues, then you'd be best off taking it in for new tires.

Bulges or Cracks

If your tire is deflating, it will naturally start to bulge out on one side. Air leaks or low tire pressure are signs that you need to have your tires replaced, so make sure that you get your car serviced as soon as possible. These issues can usually be traced back to a foreign object getting into your tire and causing damage to the sidewall. Bulges or cracks in your tires can indicate a blowout is on the horizon, and an accident isn't that far behind.

Temperature Changes

Temperature has a direct impact on the rubber tires our cars use. In the winter, tire pressure drops in alignment with the weather. An underinflated tire will generate excess heat and will wear out quicker. If left unattended, your tires will need to be replaced sooner than you would like. Try to pay attention to whether your tires look like they are properly inflated, so you can identify when the temperature starts to play havoc with your tire pressure. Do you not trust your ability to gauge your tires? You can always take your car to your preferred mechanic and have someone check them out if you're unsure.

Changing with the Seasons

Depending on your climate, changing your tires seasonally may factor into the decision of when to change your tires. If you live in an area where the traction provided by snow tires makes sense for the duration of the winter, changing your tires from your normal all-season tires to your winter-specific tires will help reduce overall wear and tear. You can replace your tires with your winter set once the outdoor temperature consistently drops below 45 degrees Fahrenheit.


Keeping your car in good driving condition can be a difficult task. As a complex piece of machinery, you need to be vigilant for signs that your vehicle isn't performing the way it should. For more tire-changing information, contact Piazza Subaru today!
