Five Signs That Your Tires Need to be Replaced

It can seem like no big deal, but believe it or not, keeping an eye out for the indicators that a tire has finally given its all in service to your Subaru ride is more important than you might think. According to the authorities at the National Highway Traffic Safety Administration (NHTSA), tire failures cause approximately 11,000 motor vehicle accidents each year. The thing is, the causes of such failures can easily be missed or overlooked, slipping one's mind until it's nearly or all too late.

So, heed a bit of advice from the experts here at Royal Subaru: it's a good idea to examine your tires once a month to stay on top of any problems. If you notice any of the following, it's likely time for a new set of four.


  • Bulging, slices, or cracks. See any of these on that new Subaru Impreza sedan or hatch? The former suggests partial deflation, and it's at least a sign of suboptimal tire pressure or air leaking, often caused by the latter.
  • Worn treads. To determine the condition of yours, perform the tried-and-true penny test. Put a penny in a tread, with the president's head pointing down. If you can still see the top of the head, you've got the namesake problem. Moreover, many tires today have rubber wear bars woven into the tread at certain depths. If you can see them, it's definitely time to change tires.
  • Tire pressure troubles. Deflation occurs naturally at about one pound per square inch, or PSI, per month. Check occasionally to make sure that your tires are at the right pressure. It can mean not only better ride quality for that brand-new Subaru Forester through the southern Indiana bush. It may also indicate a nascent leakage problem you've now caught before it has gotten worse.
  • Drastic environmental temperature changes. A nod to the prior symptom, tire pressure tanks when it's frigid outside, causing de facto semi-flattening, and in summer, tires can get extremely hot. An overheated, underinflated tire, say, on a frequent pleasure cruiser like the high-octane Subaru WRX, gets into a vicious cycle, working harder, producing even more heat, and thus wearing more quickly.
  • Abnormal vibration. You'll feel a touch of the road underfoot when you drive, to be sure, but if it's pronounced and feels like it's below your seat rather than at the wheels, your rear tires may be imbalanced. If bad vibes extend to the steering wheel, it could presage suspension issues. Have a not-so-smooth ride either way? In this case, it might be your best bet to bring your Subaru car or SUV in for an inspection.


Ultimately, when it is, in fact, time to replace your tires, it's best to do so in pairs if not all four at once. It'll mean the difference between making the most of tire performance and traction and, say, a new Subaru Outback that doesn't orienteer so well off the beaten path.
