Automotive Tips from Autotronics of St. Peter: When to Replace a Damaged Tire

Repair or Replace? That’s a question St. Peter drivers ask when they have tire damage. Some punctures cannot be repaired because of their size or location. Punctures larger than a quarter of an inch (6.4 mm) are considered too large to be safely repaired. Punctures in the sidewall or near the shoulders may not be able to be repaired. And sometimes there is internal damage revealed on inspection that indicates the tire should not be repaired.

Run flat tires should not be repaired. Repairing high performance tires may make them unsuitable for motorsports. Your friendly and professional Autotronics of St. Peter service advisor can inspect your damaged tire and tell you if it can be safely repaired or if it should be replaced – and then help you get back on the roads around St. Peter.

Always on Guard (TMPS)

One of the most important things you can do to keep your vehicle running safely is to make sure your tires are properly inflated.  If one or more is vastly over- or underinflated, that has the potential to cause major handling problems and may result in a dangerous accident.

All vehicles in recent years are equipped with Tire Pressure Monitoring Systems, or TPMS.  One system uses small sensors in the tires that continually check the pressure in each tire.  That sensor sends a signal to computers in your vehicle which turns on an instrument panel light warning of low pressure when at least one is very low. Or it may update a numeric reading on your instrument panel which gives you an approximation of how many PSI (pounds per square inch) of air is in each tire. 

Another system works with your antilock brake system to measure the size of your vehicle’s tires.  When one wheel is going faster than another, it will spin faster. A computer sees that and alerts you that tire’s diameter is smaller than the others and therefore must be underinflated.

No matter what system you have, it’s also helpful for you to know how much pressure each tire is supposed to be inflated to.  You can find that on a label on the driver’s side door sill. In addition, the TPMS system should not be used as a substitute for checking your tires with a tire gauge since the TPMS accuracy usually isn’t quite as precise.  Keep in mind that tire sensors can fail, so each system acts as a backup for the other. 

Since many vehicles these days don’t have spare tires, it’s good to know that your TPMS can warn you if you have a leak in one of your tires.  If you get a low-pressure warning, many systems will tell you which tire is low, so you can do your own visual check.  Often you can see if you’ve picked up a nail or a screw if it’s sticking out of the tread or near the sidewall.

Being able to receive an early warning from your vehicle of abnormal tire pressure may give you a chance to safely drive to a service center before your tire slowly goes completely flat (which can ruin the tire and badly damage the rim). It also may ultimately prevent you from being stranded somewhere with a flat tire or, most importantly, having a sudden blowout on the road.

Tracking True in St. Peter: Wheel Alignment

At Autotronics of St. Peter, we occasionally see severe tire damage that could have been prevented with proper wheel alignment. During a Autotronics of St. Peter alignment service, your vehicle is put on an alignment rack where the tires, steering and suspension parts are inspected for problems. Then the alignment is charted and checked against the vehicle factory settings. Adjustments are made to bring the wheels back into alignment. This gets all four wheels moving in precisely the same direction.

If you don’t remember hitting a pothole, how do you know if your wheels are out? The most obvious sign is that your vehicle pulls to one side. Also, your steering wheel may not be centered when you’re going straight. If you’re in the habit of checking your tire wear regularly, you may notice the edges of one or more tires rapidly wearing down. You should have your St. Peter auto service center look it over. Of course, if you’ve been in an accident, you should get your alignment checked.

It’s not surprising that a forceful impact can seriously knock tires out, but remember that a series of smaller ones can add up. That’s why your vehicle manufacturer recommends periodic alignment checks. If your vehicle owner’s manual doesn’t advise a specific interval, once a year might be appropriate. Check with your Autotronics of St. Peter service advisor. As with most other preventive maintenance services, the cost of the alignment is a heck of a lot cheaper than having to purchase new tires earlier than expected.
