All new passenger vehicles on our St. Peter, MN, roads now have tire pressure monitoring systems – TPMS for short. They are designed to alert you if your tires are underinflated. Since they are fairly new, a lot of people have questions about them.

First off, the most important thing is that you still need to check your tire pressure every week – or at least every time you gas up. The TPMS system alert comes in when your tire is 20 percent below the factory recommendation. So if the recommended pressure is 34 pounds per square inch, the TPMS warning won’t come on until the pressure is at 28 pounds. That’s significantly underinflated, enough to raise safety concerns.

The worst is tire failure. A severely underinflated tire can overheat and fail. Also, handling degrades to the point that you may not be able to steer out of trouble. Also underinflated tires wear out faster and they waste fuel. So it’s costly to not stay on top of proper inflation.

What’s the practical value of the TPMS system? Well, it’s twofold. First, it can alert you when your tire is losing pressure due to a puncture or a bent rim. That’s an important warning that you might not have gotten until next time you gassed up.

The second is that we all occasionally forget to check our tire pressure. So it’s a fail-safe system to let you know there’s a problem brewing.

Other things can cause your TPMS system to go off. The system also monitors itself. The sensors that are mounted in the wheels have little batteries that send a signal to the monitor. The batteries go dead over time and the TPMS system will let you know. And the sensors could break. Also road salt from our MN roads can ruin them.

There’s also a hassle factor that your St. Peter, MN, tire center has to contend with. For example, when you have your tires rotated in St. Peter, the TPMS system has to be re-calibrated so that it knows which tire is on which corner of the car. Same is true for when you have new tires or winter tires installed. Flat repairs, as well.

That takes extra time. And it requires the right equipment and training. Special – and expensive – tire change machines need to be used with some sensors. It’s all complicated by the fact that there are a number of different TPMS systems in use so the tire professionals at Autotronics of St. Peter need equipment and training for each kind. Tire centers have had to raise the price of some of these basic services to offset their increased costs.

Also if you add custom wheels on your vehicle, you need to put in new TPMS sensors if your originals won’t work on the new rims. If you don’t your TPMS light will be on constantly and you won’t have the benefit of the warning system.

All in all, the mandated TPMS systems will save lives, so they’re worth the added hassle and expense.

There’s a segment of the St. Peter area population that’s not committed to proper vehicle maintenance.

Now, the ignition system in your vehicle is electronic and controlled by the engine management computer. Spark plugs rarely get fouled and will last for as much as 100,000 miles (160,000 kilometers). So tune-ups used to force you in to Autotronics of St. Peter for service, and while you were there you just took care of whatever else was on the list.

Also, in recent years, a large percentage of new vehicles in St. Peter have been leased. These folks plan on turning the vehicle in after two or three years, so they haven’t focused on the maintenance that helps a vehicle last longer.

Given all that, what’s the benefit to keeping up with factory scheduled maintenance? Well, your vehicle will perform better and return better fuel economy.

Those benefits pay for themselves as they go along. The big plus is that major repairs are prevented. And these aren’t just repairs that are a long way off. Modern vehicle engines are far more sophisticated and have many parts that are in critical need of proper lubrication. Missing just one oil change can allow oil sludge to start forming. Sludge clogs small engine passages, robbing parts of the lubrication they need. An expensive failure could easily occur within two or three years.

And modern engines require more sophisticated fluids. Because of the different types of materials that are used to make auto parts, things like aluminum, plastics and steel, different types of additives are required to protect automotive components from corrosion. These additives deplete with time as well as with use.

Taking care of the little things now prevents big problems later. At Autotronics of St. Peter, we have been taking care of all those little things for years. Your vehicle still needs to be taken care of – it’s just that some of those points of care have changed with automotive advancements. The need for proper maintenance in St. Peter drivers vehicles did not go away.

Any St. Peter driver who understands preventive maintenance knows that “if it ain’t broke, don’t fix it” is bad auto advice. Replacing a part before it breaks is much less costly for St. Peter residents than repairing the engine damage that comes after a part breaks or fails. A good example of this is the serpentine belt.

The serpentine belt gets its name because of its circuitous path around the engine. The serpentine belt is driven by the engine and powers a number of systems, as follows:

1. The serpentine belt spins the compressor that generates the cool air for the air conditioning system.
2. The serpentine belt powers the alternator. The alternator generates electricity for use in the vehicle’s electrical systems and to charge the battery. Without the alternator, the battery wouldn’t last more than a few miles.
3. In many St. Peter residents’ vehicles, the serpentine belt runs the pumps for both the power steering and the power brakes. In other vehicles, the power steering pump may be electric and the power brakes may use a vacuum boost.
4. On many vehicles, the serpentine belt powers the water pump. The water pump keeps coolant circulating through to maintain appropriate operating temperatures. In some MN vehicles, a timing belt runs the water pump.

When a serpentine belt fails, all of these systems fail as well, which can lead to engine impact.

Replacing parts before they break saves money for St. Peter residents by preventing more repairs and the frustration of having your vehicle in the shop for an extended period of time. If you’re looking for an adage to apply to good car care, you might remember the old story of how “for want of a nail, the kingdom was lost.”
