It's no secret that replacing your tires is expensive. Some people try to ride them out as long as they can, but that's not necessarily the safest thing to do. The question is – do you know how to tell when you need new tires?
The Pressure Is Low
If your tire pressure is low then you may need to get new tires. When the tire pressure is too low then there is too much of the tire touching the ground. This will result in wearing out and damage of your tires. They could also get too hot which might result in them coming off and causing an accident. It's a good idea to check your air pressure monthly and refill if they are a little low. If it happens more often than it should, then you might have a leak. This would mean you'd need to get a tire to replace it.
The Tread Is Worn
Tread is there to improve traction by diverting water from underneath the car when you drive through it. Low tire tread increases the risk of hydroplaning. Fortunately, it is easy to tell when your tire's tread is too low because all tires have tread wear bars that appear when the tread is considered too low.
You See Cracks or Bulging
If you see a bubble or a bulge in the tire, the inside of the tire has been damaged. Continuing to drive on a damaged tire is dangerous because you are at an increased risk of having a blowout. A blowout is where the tire explodes and shreds while you are driving. It happens suddenly and can cause you to lose control of the vehicle.
Cracks and bulges can also occur if the tires are not full of enough air for extended periods of time. Basically, this means you let your vehicle sit in the driveway with flat tires – or tires low on air – for a long period of time. If your tires have cracks or bubbles on them, you should have them replaced as soon as possible.
Your Tires Are Vibrating
Tires vibrating while driving could be a sign the alignment on the vehicle is off. While it may be normal for your vehicle to vibrate a little while driving, that vibration should not suddenly get worse. If it has gotten worse, it is a good idea to have a mechanic see if an alignment could fix the problem.
In some cases, you could also have an issue with a suspension piece. This is also a problem you are going to want to get fixed as a broken suspension piece could come loose or fall off of the vehicle and pop your tire. Furthermore, driving a car that needs an alignment or a car with bad suspension pieces is also going to force your tires to work harder. This, in turn, means you will have to replace them sooner.
Be mindful of your tires and check them out often so you can keep yourself and your car safe on the road. If you notice any of these signs don't delay going to get them checked out. It's better to be sure your tires are in good shape then to risk driving on bad ones.
