The Truth about Tire Pressure (Tire Inflation)

Most light vehicles (under 10,000 pounds/4,500 kg) in North America sold from 2008 model year on have a feature that many people are confused about.  It’s the tire pressure monitoring system (TPMS).  You may have some experience with it yourself if you own a newer vehicle.  Vehicles with TPMS have sensors in each tire that are supposed to warn the driver when tire pressure gets dangerously low.  That’s important because tires that are significantly under-inflated can cause very serious accidents.

Unfortunately, many drivers think the TPMS does all the work keeping track of tire pressure. To them, as long as the warning light or gauge isn’t giving a warning, the tires must have the proper amount of air pressure in them.  That’s not the case.

Tire pressure monitoring systems aren’t all created equal.   Some give you a digital readout of the pressures in each individual tire.  But many simply have a warning light that looks like the cross section of a tire with an exclamation point in the middle.  If you don’t know what it is, it’s because it’s not instantly recognizable as a tire.  In fact, one company that makes TPMS, Schrader Performance Sensors, surveyed drivers.  Their study showed that more than 40 percent of drivers didn’t know that that warning light was. 

One out of 5 of the drivers who did know what the light was only looked at their tires after the light came on to see if they could see any that needed air; they never checked them with a tire gauge or had someone else do it.  Ten percent of them didn’t do anything when the light came on.

In most vehicles with TPMS, the warning comes on only when the tires are more than 25% underinflated.  The American Automobile Association says that’s under the pressure you need for safe vehicle operation.

The bottom line is once a month you should make sure your tires are inflated to the manufacturer’s recommendations.  That means each tire should be measured with an accurate, external tire gauge.  To be confident you are getting a correct reading, take your vehicle to a reputable service facility where their equipment is calibrated and they know what they’re doing.

Severely underinflated tires can contribute to an accident that kills or severely injures people.  The idea behind TPMS is well intended, but the system was never meant to replace regular inflation measurements and maintenance.  Periodically have your tires checked for proper inflation.

Light’s Out! Trouble Ahead (Exterior Light Bulb Service)

Whether or not your exterior light bulbs are all working probably is not at the top of your list when you think about your vehicle.  But those exterior lights are more important than you think, and they’re vital to your safety and that of other drivers near you.

Headlights are important.  Not only do they help you see safely down the road at night, they also help oncoming drivers know that the vehicle they’re approaching is not a motorcycle.  Both headlights should be working properly and aimed so that they don’t blind other drivers.

Taillights are also important for a few reasons.  They tell drivers what your intentions are (changing lanes, turning, stopping).  So, the bulbs back there must be all in working order for maximum safety. Ditto for the front turn signal lights.  They alert oncoming drivers to your lane changes or turns (if you use your turn signals!).  Some side mirrors also have turn signal bulbs in them.

There are a few other important bulbs.  You may not care about the ones that illuminate your rear license plate, for example. But they are there to help public safety forces identify your vehicle. In fact, in many municipalities you can be pulled over and ticketed if ANY of the standard lights are burned out.  So not only does having all your exterior lights working improve your vehicle’s safety, it may keep you from getting a ticket.

Many newer vehicles have a light on the instrument panel that will go on if on-board computers detect voltage problems in any of your vehicle’s bulb circuits.  Sometimes it can be hard to figure out which light may be not be working since there are so many. Sometimes it’s simply a matter of replacing a bulb, but it may be an electrical problem causing the problem.  Stay legal and safe by having your service repair facility diagnose and fix a non-working light, a really bright idea, don’t you think?

St. Peter Customer Detective Work

One might say the most challenging part of being an automotive service technician at Autotronics of St. Peter is diagnosing a problem before it can be fixed.

Cars are made up of a bunch of complex systems. There usually could be a number of reasons for any given symptom. So, it’s challenging to track down the actual cause of the problem. And it can be frustrating for the vehicle owner because it can take time and money to get to the bottom of a problem. If it’s not something obvious, it’s easy for the customer to focus on the fixing and not the diagnosing.

Let us at Autotronics of St. Peter introduce you to something we’ll call ‘Customer Detective Work’ –  helping your technician find clues to what’s wrong.

We start with the detective basics: What, Where and When. Play along with me; You come in to Autotronics of St. Peter and your car is making a funny sound…

    • Q: Where’s the sound?
    • A: Around the right front wheel.
    • Q: What kind of sound?
    • A: Kind of a clunk, clunk sound.
    • Q: When do you hear the sound?
    • A: When I turn and accelerate. 
  • Q: Right and left? Forward and back?

Do you see where we’re going? You’re gathering additional information to help your technician at Autotronics of St. Peter know where to start. Based on your car and the tech’s experience, he’ll know where to look and can start with the obvious suspects.

You can see how that would be more helpful than dropping the car off with a note that says “making a funny noise.”

If the tech can experience the problem personally, he’s better able to make a diagnosis and repair and then test to see if the repair solved the problem.
