Tips for Buying Oversized Mag Wheels

Oversized wheels are becoming increasingly popular, and you may be asking yourself if bigger is better. As always, when you’ve got a question about your car, there usually isn’t a simple answer—it’s dependent upon what you want out of a set of mag wheels.

Your mag wheels Brisbane should be appropriately sized for your vehicle and the loads you carry. For example, the wheels on a commercial vehicle are larger because they typically carry heavy loads. If you just want big wheels for their looks—go for it—but you should remember that they’re heavier and they’ll raise your vehicle’s center of gravity.

Lightweight Wheels Outperform Heavier Ones

For performance, lightweight mag wheels can’t be beat. The logic is simple: As they rotate, your wheels, due to inertia, want to continue going at a constant speed in a constant direction. The heavier your wheels, the more difficult they are to control. As a wheel’s diameter increases, its perimeter becomes heavier. The wheels get harder to steer, and shocks have to work harder to keep your car on the road.

Your Tyres Must Stay In Contact With The Road

Good road handling is attained by keeping the tyres’ contact patch on the road at all times. If your mag wheels bounce or if your tyres don’t remain on the road’s surface, your car will lose grip. It can be difficult to keep the rubber on the road at high speeds or on uneven roads.

The greater the weight to be handled by your vehicle’s suspension, the harder it has to work to keep your mag wheels Brisbane from bouncing. Sports car makers focus on minimizing unsprung weight in order to keep tyres on the road.

Get Lower Profile Tyres for Better Performance

The main performance advantage to larger wheels is that it allows you to fit tyres with stiffer, lower sidewalls without a change in ground clearance and wheel perimeter. Low-profile tyres keep more of the tread on the road than a flexible, high sidewall does. To an extent, the improved handling makes up for the disadvantages of using heavier, bigger wheels.

Big Wheels: They Need to be Light

Steel barrels become prohibitively heavy at approximately a 16″ diameter. For everyday use, cast mag wheels are a good option in sizes up to 20″. In performance applications, forged wheels are superior when sizes reach 18″. A forged wheel is much lighter than a cast wheel, as the construction process alters the metal’s molecular structure.

For increased performance, the most important factor is the weight of your mag wheels Brisbane. Replacing standard wheels with an equivalently-sized alloy will gives you improved road handling and braking, with no decrease in ride quality. When plus sizing your wheels, your car will handle better—but you may see diminished comfort. While big wheels look better, you’ll have to choose carefully to see the benefits.

Benefits and Drawbacks of Plus Sizing

Maybe you want to put mazda bt50 wheels on your car, or maybe you want to downsize your wheels to accommodate beefier tyres. You head over to the local tyre store, and the salesperson tells you about plus sizing, which determines which tyre sizes will work on your Simmons wheels. Using larger-than-normal wheels and tyres is referred to as plus sizing, while using a smaller set is called downsizing. Both choices have benefits and drawbacks, and the reasoning behind each is different. Here, you will learn about upsizing and downsizing wheels and tyres, and you will learn how your choice can affect other parts of your vehicle.

Benefits and Drawbacks of Plus Sizing

Why Should You Plus Size?

Most people upsize their wheels and tyres for aesthetic and performance reasons. Larger wheels are definitely eye-catching, and they can greatly change the way a car looks. As to performance, wheels of up to 18 inches can provide better braking, steering, handling and ride comfort, while having adverse effects on fuel mileage and acceleration. Beyond 19″, however, the positive effects diminish as the negative ones grow.

Why Should You Downsize Your Tyres and Wheels?

In most cases, downsizing is great for winter tyres, which become substantially more expensive as sizes grow beyond 17″. The narrower a tyre, the better it handles on icy or snowy roads. If you have 18-19″ Simmons wheels and want a spare set to hold snow tyres, it’s a wise choice to downsize the extra set.

Losing and Gaining Inches

To maintain the outside diameter, when you plus size by one inch, you must take away an inch from the tyre’s standing height. The reverse applies when downsizing, and this is why 22″ and bigger rims come with low-profile tyres that resemble a thick rubber band. Determining proper sizing requires some math, because aspect height is a percentage of the tyre’s width. Do the math as follows:

  1. Multiply the tyre width by the aspect ratio, given in decimal form. (For instance: 235×0.55 = 129.25)
  2. Convert aspect height into a figure given in inches. (129.25/25.4 = 5.08)
  3. Multiply the answer by 2. (5.08×2 = 10.16)
  4. Add the tyre’s inside diameter. (17+10.16 = 27.16)

Perform the same steps for the new tyres’ size. It’s a complicated bit of math and it takes effort, but most online sellers of XXR 527 wheels provide calculators. Simply input the current tyre size and the one you want, and the calculator will give the difference. In most cases, you’ll also be able to find out how bigger or smaller tyres will affect speedometer accuracy. Ideally, your new Simmons wheels will provide a 1% difference or less. Your tyre and wheel professional can give great advice, but with the steps above, you’ll know just what they are talking about.
