Upsizing Wheels and Tires With Niel's Auto Service

Many Thousand Oaks drivers want to accessorize their vehicle - you know, make it theirs. One of the easiest ways to get a custom look is to get some new wheels. There are thousands of wheel designs at Thousand Oaks area tire shops to get you the look you want. And for many Thousand Oaks drivers, that look includes bigger wheels. It used to be that cars came from the factory with 15 or 16 inch wheels. Now 16, 17 and even 18 inchers are standard. And the factories are offering optional wheel packages up to 20 inches or more.

So let's talk about what to consider when you want to upsize your wheels. It's not exactly a DIY project, so you need to know a thing or two before you get started. The most important term to know is rolling diameter. The rolling diameter is simply the overall height of your tire. Unless you want to modify your vehicle suspension, you'll want to keep your rolling diameter the same when you upsize your wheels.

Let's think about those three golden doughnuts in front of you. They're all about the same size. So if we pretend they're tires, they would have the same rolling diameter. The doughnut hole is the size of the wheel. Now pretend we've made the hole bigger on some. That's like having a bigger wheel - but the rolling diameter is the same.

It's important to keep the rolling diameter the same for several reasons. First of all, if the tire is bigger, it might not fit in the vehicle wheel well. Next the speedometer, odometer and anti-lock brake system are all calibrated for the factory rolling diameter. In order for your anti-lock brakes to work properly, the rolling diameter must stay within 3% of the factory recommendation. If you ignore that, you run the risk that your anti-lock brakes won't work properly.

Some have vehicles with electronically-controlled suspension that will be negatively affected by changing the rolling diameter. Let's think about the doughnuts again. You see, as the size of the wheel gets bigger, the sidewall gets shorter. The tire holds less air, so the sidewalls are made stiffer to compensate.

Low profile tires from top manufacturers use special compounds that give the sidewall the strength it needs without compromising ride quality. As you increase your wheel size, you'll typically get a slightly wider tire. This means that you have a larger contact patch. The contact patch is part of the tire that contacts the road. Because there's more rubber on the road, the vehicle will handle better. And braking distances will be shorter. A lot of Thousand Oaks folks with trucks or SUVs love the extra control.

CA drivers need to watch out that the contact patch isn't so big that the tires rub in turns or over bumps. What we're talking about here is fitment. Your tire professional at Niel's Auto Service can help you get this right. He'll install your new wheels, add spacers if needed to make sure your brakes fit inside your new wheels and get you rolling.

Also, if you drive off-road in CA a lot, you may need a higher profile tire to protect your new rims. And make sure your new tires have the load rating you need if you tow a trailer or haul heavy loads. Again, your tire professional at Niel's Auto Service knows how to help.

And don't forget about tire pressure. If you have larger rims, your new tires will hold less air and they'll need to run a slightly higher pressure. Forget that and you'll wear your tires out fast. Finally, get an alignment at Niel's Auto Service after you get your new shoes.

See the Light (Automatic High Beam Dimmers)

It's happened to all of us.  We're driving down a highway at night and over a crest appears a car with its high beams blazing.  You are momentarily blinded, hoping the other driver will switch them to their low beam setting and restore your vision.

Not only do we not appreciate being blinded, face it; we don’t want to be that other driver, either.  You know, the one who forgets to turn down their high beams.

Why do we want high beams in the first place? They can improve safety when used correctly, giving drivers more reaction time since they can see farther down the road.  But research has found many drivers either don't use them or, when they do, they frequently forget to switch to low beams.  Enter the automatic high-beam dimmer.

The quest for the perfect one began back in the 1950s, General Motors invented something it called the "Autronic Eye." It was a phototube which sat on the dashboard and turned down your beams when it saw other headlights.  While touted as being the biggest advance in night driving safety in 30 years, it didn't work all that well.  But as technology got more advanced, systems improved.

Today's automatic high beam dimmers usually have a camera in the rear view mirror (pointing forward).  When the camera sees lights, software in the system's computer attempts to determine the source of the light, whether it is an oncoming vehicle, taillights, ambient city lights, street lights or the reflection off of a street sign.  It then adjusts the headlights to operate high beams if appropriate or a less-blinding mode if they’re not.

Some automakers are striving to make their headlight systems smarter and safer by developing lamps that can avoid blinding oncoming drivers by means other than simply dimming them. One idea? Splitting the beams so they will block just the portion that shines into the eyes of oncoming drivers.

It's a long way from the Autronic Eye.

Automotive Tips from Niel's Auto Service: Air Conditioning Inspection

Most auto manufacturers recommend an interval for an air conditioning system inspection. The inspection uncovers leaks, worn hoses and assesses the condition of the other components.

Environmental laws in some around Thousand Oaks require leaks to be repaired before refrigerant can be added. Also some parts manufacturers require other components to be replaced along with certain failed parts in order to maintain the new part warranty. This is because a given failure may be the result of another worn or damaged part that will, if not replaced, prematurely damage the new component.

Niel's Auto Service in Thousand Oaks is fully equipped to restore your flow of cool air.
