Rotation Explanation (Tire Rotation Patterns)

You may notice that when you get your vehicle’s oil changed, your service adviser may recommend that you have your tires rotated at the same time.  The reasons are simple.  That will allow your tires to wear more evenly and reduce the noise your tires make as you drive down the road.

There are different ways of rotating tires. If your vehicle has non-directional tires and the same size wheels at each corner, here are the different rotation patterns.

For all-wheel drive and rear-wheel drive vehicles, one is called the rearward cross pattern.  The rear tires are moved to the front and stay on the same side of the vehicle, and the front tires are moved to the rear on the side opposite of where they were on the front. 

For all-wheel and four-wheel drive vehicles, use the X pattern.  The rear tires are moved to the front on the opposite side of the vehicle, and the fronts are moved to the rear on the opposite side of where they were on the front.

For front-wheel drive, there’s the forward cross.  The front tires are moved to the rear wheels on the same side of the vehicle as they were on the front and the rear tires are moved to the opposite side of the vehicle than they were on the rear. 

If you have directional tires (they only can be mounted in one direction) and the same size directional wheels, the rear tires are moved to the front on the same side of the vehicle where they were, and the front tires are moved to the rear on the same side they were on the front.   And if you have tires with different sizes of non-directional tires and wheels on the front and rear, rotation will be from one side of the vehicle to the other. 

If you have a spare, it’s put into the rotation using a forward cross or rearward cross. 

Yep, that’s a lot to keep straight.  So, we suggest letting your service advisor recommend the right rotation pattern for you at the interval your vehicle’s manufacturer specifies.

The Vivacious Vernal Vehicle (Preparing Vehicle for Spring)

Most of us look forward to spring because the days are longer, the weather’s warmer and we can finally get our vehicles into warm weather mode.  Here are a few things that will breathe fresh energy into anyone’s car, SUV, truck or van.

First thing is a good cleaning, especially underneath. If you live where salt and brine are used on the roads, it’s important to get that off.  One thing to note… if you hose off your undercarriage, be careful not to get your spark plugs/wires wet.  You could notice your vehicle running rough plus the Check Engine light may come on. It usually dries out quickly, but if the engine light stays on for more than a couple of days, have your service facility check it out.

Next, replace your windshield wipers.  They’ve taken a beating through the winter. New ones will have fresh rubber and you’ll see clearly (and safely) out your windshield again.

Have your brakes inspected.  That salt doesn’t do your brake’s metal components any good.  Have a technician make sure your pads and rotors are clean and properly lubricated so they can stop you when you ask them to.

Speaking of wheels, it’s a good time to have your tires checked, too.  Road debris and potholes can take a toll on tread and sidewalls. It may also be a good idea to have a technician check your alignment since you likely have hit something pretty hard on a patch of rough road at some time during the winter.

Make sure your tire pressure is appropriate for the rising temperatures. As the outside air warms up, your tire pressure climbs without you adding any air.  Make sure it’s what the manufacturer recommends.

Finally, treat your vehicle’s interior to a thorough refresh.  Those floor mats and carpets may be white with salt; clean ’em up.  Get rid of wrappers, drink lids, empty water bottles and anything else that’s fallen down.  And if you need to, have your upholstery cleaned so it looks and smells new. A clean exterior is nice, but since you spend your time inside your vehicle, it’ll feel even better when your cabin is sparkling fresh.

Refresh Your Brakes (Brake Fluid Exchange)

Brakes are one of your vehicle’s most important safety components, and you may have noticed that they don’t stop as surely as they used to.  Maybe it takes you applying a little more pressure to them than before, or perhaps you get the feeling that they’re not stopping you as quickly.

Those could be signs that your brake fluid needs changing.  Hydraulic brake systems use a fluid that enables the brakes to apply their stopping power to the wheels.  That fluid can wear out, degrade, become contaminated or pick up air and moisture.  All those can eventually contribute to brakes that feel sluggish. Driving with old, worn-out brake fluid may also shorten the lifespan of other braking components.

Our technicians can evaluate your brake fluid to see if it needs changing. Your vehicle’s manufacturer recommends how often that should be done, and when it needs changing may depend on how and where you drive. Our technicians can check the condition of your brake fluid when you have your regular oil changes. 

A technician will remove the old fluid and replace it with the type the vehicle manufacturer recommends. They will also bleed the air from the brake system, check it for any leaks and inspect other components such as the hoses, rotors and brake pads. Because brake fluid is combustible and toxic, it’s important that it be disposed of properly so as not to create environmental damage. 

And just a reminder that if you continue to drive with old, contaminated brake fluid that’s past its lifespan, other components of your brake system can fail.  Let’s face it. Brakes that don’t stop you when you need them can endanger your life—and the lives of those near your vehicle.

Read a Good Tire Lately? (Tire Wear)

There’s lots of good information to read in books and online.  You might not know that you can also “read” your tires and learn a lot about what shape they’re in and if they are in need of attention. It’s important to know how your tires are doing because a tire failure can be very dangerous to you, your passengers and others on the road near you.

You read your tire by looking at the surface that rides on the road, where the tread is.  Check out the outer and inner edges.  If you notice there’s more wear on the inner or outer edge than on the rest of the tread, your vehicle could be out of alignment.  Wear on an inner or outer edge could mean your wheels are leaning too much to one side.  When you see this, visit our service center soon to have the alignment checked.

What about if both edges are worn? That could be a sign that you don’t have enough air in that tire.  In an underinflated tire, the middle is not contacting the road surface as much as the edges, so the edges wear down first.  It could also mean that you’re taking corners too aggressively or your tires haven’t been rotated on a regular schedule.

Another thing you might see on your tires’ tread area is wear in the center of the tire.  That means you likely have too much air in that tire.  Too much air makes your tire contact the road in the middle more than on the edges so the middle wears down prematurely. 

You might also see some smooth spots on the tread in irregular spots. This is called cupping. This is sometimes caused by suspension problems. A technician can examine your suspension to see if it is up to the manufacturer’s specifications.

Finally, you may spot tires that are worn unevenly in a pattern that goes diagonal to the tread pattern.  This could mean your tires are out of balance, something our service center can check. They might also check alignment at the same time.

Your tires are the only part of your vehicle that contacts the road surface.  That means your acceleration, traction, steering and braking are all dependent on your tires being healthy. Maintain your tires by having one of our trained technicians read the clues and making sure they’re always in roadworthy shape.
