Go Big or Go Home: Upsize Your Wheels at Joe D'Auria's Auto

A lot of us CHERRY HILL drivers like our vehicles to reflect our personalities. We're picky about color and body style. We'll customize anything from floor mats to window tints to license plates. One popular way for NJ motorists to customize a vehicle is to get new wheels.

Wheels come in thousands of designs. Custom wheels can add personality, style, or sass to a vehicle. Many of these customizations involve getting a bigger wheel.

Fifteen- or 16-inch wheels used to be the factory standard, but today, because many CHERRY HILL drivers like the look of larger wheels, many vehicles are available with 17- or 18-inch wheels. Optional 20-inch or larger wheel packages are also available in CHERRY HILL.

If you want to upsize the wheels on your current vehicle, however, you should know it's not a do-it-yourself project. There are factors to consider to ensure your wheel change doesn't jeopardize your vehicle's safety.

First, you need to understand rolling diameter. The rolling diameter is the overall height of a tire. If you increase the rolling diameter of your tires when you upsize your wheels, you may need to modify your suspension to ensure the larger tires fit within the space and don't rub in turns or over bumps. If that's more work than you're willing to do or pay for, then you need to maintain rolling diameter when you change your wheels.

It's not as hard as it sounds. Imagine a doughnut. That doughnut represents rolling diameter, so you can't make the doughnut bigger. However, you can increase the size of the doughnut hole. That gives you a bigger wheel. Tires with reduced sidewalls on larger wheels will preserve your rolling diameter.

Rolling diameter is important because your wheels and tires still need to fit inside the wheel well. Also, your speedometer, odometer and anti-lock brakes are all programmed to work with a specific rolling diameter. You'll throw off the readings on your speedometer and odometer if you change your rolling diameter. And for your anti-lock brakes to work properly, your rolling diameter must be within 3% of the factory recommendations. While some CHERRY HILL drivers who upsize may not be concerned about meter readings, throwing off the brake system is a serious safety hazard.

Further, many vehicles in CHERRY HILL are now equipped with electronically controlled suspensions. Changing the rolling diameter will negatively affect this system as well, which can lead to a less smooth ride and lower handling performance as well as safety concerns.

Your friendly and knowledgeable Joe D'Auria's Auto tire professional may be able to reprogram your vehicle's computer to adjust for a larger (or smaller) rolling diameter.

So to maintain rolling diameter, you'll need tires with a shorter sidewall. These tires will be designed to give the sidewalls the strength they need to maintain ride quality. Consider that doughnut again. As the wheel (the doughnut hole) gets bigger, the sidewall of the tire (the width of the remaining doughnut) gets shorter. That means the tire holds less air. The sidewalls have to be made stiffer to compensate for the decreased air capacity.

To improve their strength, the shorter tires will also be slightly wider than your previous tires. But this means you'll have a larger contact patch, or, in other words, a larger area of tire making contact with the road. This can actually increase your handling performance and decrease braking distances. Many NJ auto buffs customize their wheels just for this reason—they want the improved performance rather than looks or style. If you drive a truck or an SUV around CHERRY HILL, you might be interested in the extra control an upsized wheel can provide.

Now, that larger contact patch still has to fit inside your wheel well without rubbing when cornering or when bouncing over bumps or potholes on CHERRY HILL roads. This is termed fitment, and you may need a few adjustments so your new wheels will fit properly. You may need spacers so that your brakes will fit inside the new wheels, as well.

Joe D'Auria's Auto tire professionals are experts at mounting, adjusting, and customizing wheels. They can give you a lot of good auto advice on wheels and tires, including how they affect driving performance and car care. They can help you select wheels and tires that will suit your driving needs and habits.

For example, if you drive off-road around CHERRY HILL, you should consider a higher profile tire. This type of tire will protect your rims from damage while you're bouncing over rocks. Or, if you tow a trailer or haul heavy loads around NJ, you'll want a tire with a load rating equal to your demands. Your friendly and knowledgeable Joe D'Auria's Auto tire professional can help you with these types of concerns.

Once you've got your new wheels, have your service advisor at Joe D'Auria's Auto see if you need an alignment. You don't want those new wheels and your higher performance compromised by poor alignment. Get the most out of your investment by getting the work done right at Joe D'Auria's Auto in CHERRY HILL.

Last but not least, remember tire pressure. With larger wheels, your new tires will hold less air and they'll need slightly higher pressure. You'll need to stay on top of preventive maintenance and keep them properly inflated. Be sure to check their pressure at least once a week. If you don't keep your tires at their correct pressure, they will wear out really fast. It will also affect your braking and handling performance.
