It Wears on You (Tire Rotation)

If someone told you there was a fairly inexpensive way to improve your vehicle's handling, fuel economy and extend the life of your tires, you'd probably ask, "What do I have to do?" The answer is to rotate your tires.  But you have to do it regularly.

A lot of drivers think skipping tire rotation is a way to save money.  But when you don't rotate your tires, they will almost certainly wear unevenly.  That's because when your tires touch the surface of the road, the friction and traction causes miniscule parts of the rubber to come off.  And that process isn't exactly the same on each corner of your vehicle.  Some vehicles have the drive wheels in the front, some in the rear and some on all wheels.

Rotating your tires at regular intervals minimizes the differences in the way the tires wear.  The amount and pattern will be spread out equally if your tires spend time at all different positions.  The more even the wear, the more consistent traction, handling and braking will be.  All four tires will last longer this way, and when it is time to replace your tires, they'll all be worn out the same so you can replace all four with the same model tire.

Some people who choose not to rotate their tires find that one or two will wear much faster than the others, and often they'll replace just the worn ones.  While you can find similar tires, they won't all be the same and will certainly not have the same amount of wear. 

There are different tire rotation patterns depending on several factors: front-wheel drive, rear-wheel drive, all-wheel drive, directional tires/wheels, different sized wheels/tires on front and rear axles.  Also keep in mind that when your tires are new, some tire manufacturers require you to rotate them or else they won't honor the warranty. 

Your manufacturer recommends intervals for tire rotation, so it's best to follow their suggestion.  Your vehicle service facility can advise you when you need to get your tires rotated.  And many facilities include free tire rotation for as long as they're on your vehicle if you buy your tires at their shop.

If You Drive Like a Maniac (Aggressive Driving is Bad for a Vehicle)

When someone mentions driving like a maniac, they're not talking about you, surely? Besides the safety issues of aggressive driving, you should know that your vehicle will last a lot longer if you'll just mellow out a little.  Here are four traits good drivers follow if they want their vehicles to go the extra distance.

Cool—The driver who can't wait to get to the next stoplight is just shortening the life of his or her vehicle.  Jackrabbit starts and uneven acceleration hurts your engine because the valves and cylinder heads are stressed more.  All of those moving parts will wear out faster as well as other components that are connected.  That means things like the air conditioner, power steering pump… just about anything that attaches by a belt or a pulley.  Oh, and you'll be generating more heat.  Heat is one of a vehicle's worst enemies.

Warm—If you get in your cold vehicle which has been sitting overnight, start it up and rev the engine high, you've just put a lot of stress on your engine.  That's because you didn't let the oil (that's been sitting down in the oil pan at the bottom of the engine) get to the moving parts in order to lubricate them. Some manufacturers advise that you run your vehicle for about 30 seconds before you take off.  And if it's really cold out, you may be wise to let the engine run for a minute or two before putting a load on the engine.  Also, for the first 5-15 minutes, keep your RPMs on the low side and don't jam on the accelerator.

Smooth—You're trying to get somewhere in a hurry and have to jam on the brakes while traveling pretty fast.  Just that one time can do more damage to the brakes than you would think.  Lots of hard braking can overheat your brakes and damage your rotors, wearing them out way faster than someone who drives with a smoother touch.  Hard braking also strains suspension parts, tires and engine mounts.

Smart—You know what PRNDL stand for.  Those are the letters in your automatic transmission (Park, Reverse, Neutral, Drive, Low).  Here are another couple of letters: IQ.  A smart shifter never goes into R to D without completely stopping the vehicle, unless, of course, you're anxious to spend some big dollars on your automatic transmission. 

These days, it's common to get 200,000 miles/320,000 kilometers out of a vehicle, no problem.  It just takes regular maintenance (oil changes and regular service) and one other thing.  Showing off: showing off a little moderation in driving habits with a big payoff in the end.

Weather Station on Wheels (Vehicle Sensor Maintenance)

You probably never thought about it, but your vehicle is like a rolling weather station.  It can check the outside temperature, let you know when the roads are slippery and help you deal with rain. And how it does all those things is pretty cool.

First, just like any weather station, a vehicle has sensors that measure the driving and weather conditions you find yourself in.  Some of those sensors can control computerized systems in your vehicle to react to the weather.  It depends on whether you have a 2-wheel, 4-wheel or all-wheel drive vehicle how those sensors will respond.

Let's start with temperature.  Most vehicles now have a thermometer that measures the temperature outside.  It's usually in the front, and likely will tell you on the instrument panel what the outside temperature measures.  But a temperature sensor will also tell your vehicle's computers to turn on or off certain systems like the heating or air conditioning.  If your ambient temperature sensor isn't working right, some symptoms are a malfunctioning automatic A/C or a temperature display that is way different than the app on your phone says it should be.

Your vehicle will also have sensors that measure your speed at each wheel.  They work with an onboard computer to measure slippage in any of the wheels so traction control and antilock brakes work correctly in case of slick roads.

Your vehicle can measure something called longitudinal and latitudinal acceleration, and it uses a yaw sensor to do it.  That helps it determine if you might be in an oversteering or understeering situation.  It's important because it works with your vehicle's brakes to apply stopping power to keep you in control.

A steering wheel sensor tells the vehicle's computers what the driver is doing with the wheel.  It also can work with those wheel sensors to measure how slippery the roads are, whether it be due to a wet (rain) or granular (gravel or sand) surface.  By sending different torque or braking to each wheel, it helps the driver maintain control.

More and more vehicles now have a rain sensor that can turn on the wipers automatically when they measure precipitation on the windshield.

So, you're driving your own weather station, and making sure all this data is coming in properly depends on how each component is working.  Regular service and maintenance on these systems is important to make sure they can do their job. Your rolling weather station can't predict the weather, but it can sure help you deal with it, so help it do its job right.
