No Fountain of Youth (Aging Tires)

Can you think of anyone who enjoys aging? Wrinkles where you don’t want them, gray hair, eyes that won’t focus any more, no stamina.

Believe it or not, your tires age, too, and they don’t get better the older they get. And here’s the important thing to know, even if they can still pass a tread depth test, they may simply be too old to be safe

Here’s the best way to understand this. Have you ever found an old deck of playing cards with a rubber band wrapped around them? Try stretching the rubber band. SNAP! It’s all cracked and brittle. And you haven’t stressed that rubber one bit since the time you put them in that drawer.

Now you know what’s happening to your tires. Rubber ages. Just like us, the day we come into the world, we start to go downhill (no pun intended). Oh, engineers are able to make a tire last longer than ever before. But that gas that keeps us alive—oxygen—seems to love to chemically mix with some components in rubber. Oxidation causes rubber to become hard and brittle. The rubber band test.

Is there an age test that can tell you when a tire is tool old to roll? Well, not really. They don’t all age the same. Hot climates can make tires wear out more quickly. Some experts say a tire can last up to 10 years but should be inspected every year after the age of five. Others say tires should have an expiration date at six years old.

Since no one would ever ask a tire its age, how do you know how old one is? Believe it or not, tires made after the year 2000 have a date code stamped on either the inside or the outside of the sidewall. It’s a four-digit numbers; the first two tell you the week, the second two tell you the year. So if it has the number 1916, it was made in the 21^st week of 2016.

Another way to find out if your tires still have enough life in them is to have your vehicle service facility inspect them. They look for signs of age, such as developing cracks in the rubber, the condition of the sidewalls and, of course, that old standby: tread. If it’s time to “retire” them, discuss options with your service advisor.

Steering You Right (Power Steering Signs of Problems)

Nearly every modern vehicle on the road today has power steering, a wonderful invention that makes steering take far less effort than it did in the “good old days.” Today, we take our steering for granted: until something goes wrong, that is.

Most power steering these days is rack-and-pinion, the rack being a metal bar between the front wheels with notches in it and the pinion being a gear whose teeth fits into those notches. Adding power assist makes it easy to turn. That assist comes in the form of hydraulic fluid that is pressurized by a pump powered by the engine, an electric motor that adds a power assist or a system that uses both an electric motor and hydraulic fluid.

Your vehicle usually gives you a heads up that something is going wrong with its steering. Here are a few signs to look for:

A humming, whirring, rubbing or grinding sound coming from you engine compartment when you turn.
Signs of hydraulic fluid leaking, such as wet spots under your vehicle.
The smell of burning oil while you’re driving.
Steering wheel hard to turn or vibrating.

If you notice any of these signs, it’s a good idea to have a trained technician check them out. They may be signs of:

Power steering pump going bad
Steering rack or gear seals wearing out, causing them to lose hydraulic fluid
Broken fluid hose
Defective power steering cooler
Loss of pressure in the power steering gearbox
Worn out steering pump belt
Failing electric power steering motor

It’s important to have these checked out sooner rather than later. You need to be able to steer properly in order to drive safely. Plus, some of these problems can cause more serious—and expensive—damage if they’re not fixed. Power steering is a wonderful feature of your vehicle. Keep it well maintained and it will steer you right.

Follow the Bouncing Vehicle (Bad Struts and Shocks)

If you hit a bump in the road and your vehicle just keeps bouncing up and down for a lot longer time than it used to, you may have bad struts and shocks. They’re the things that help to keep your vehicle’s wheels and tires planted to the road surface.

But they don’t last forever. With care and depending on where and how you drive, shocks and struts should be replaced at intervals ranging from 50,000 miles/80,000 km to 100,000 miles/160,000 km. If you drive on bumpy roads with a lot of potholes, that interval will likely be shorter. Rough surfaces can take their toll.

But how do you know if your shocks and struts are doing their job properly? The best way is to have your vehicle checked by a technician. He or she can inspect the shock absorbers and struts for leaks, corrosion and damage. Mounts and bushings can also go bad and they should be evaluated as well. A thorough examination by a technician will also include looking at other suspension parts. Some may contribute to making your vehicle behave the same way if they’re broken, corroded, worn or bent.

If you need new shocks and struts, your service advisor will make sure that you get those that meet manufacturer’s specifications. That’s important because they want to make sure you’re getting the handling and performance engineers designed your vehicle to have.
