Plus Sizing Tires & Wheels

Two tires of different widths and diameters sitting next to one another

Plus sizing refers to replacing your original equipment wheels with larger diameter wheels and wider tires with a shorter sidewall. The overall diameter of the original tire stays the same, helping you preserve the integrity of the gearing, maintain speedometer accuracy and ensure that the new tires and wheels fit properly.

Looking to upgrade your wheels and tires?

When it comes to upsizing your tires, there's a few things you should know.

"Plus one" means that you increase the wheel diameter by one inch more than the original equipment (OE) wheel. "Plus two" means increasing the wheel diameter by two inches, and likewise with "plus three" increasing three inches, and so on. "Plus zero" just means the same wheel size as the OE but an increase in just the tire's size.

For example: You have a 16x6.5 wheel and 205/55R-16 tire. A typical plus one (1") size would be a 17x7 wheel and a 225/45R-17. Then, a plus two (2") would be 18x8 and 235/40R-18.

18x8 wheels are a pretty popular upgrade and come in a large variety of available fitments.

When it comes to downsizing, "minus one" is a decrease in wheel size by one inch. It's common to downsize in winter since this increases the tire sidewall height and may even lower the cost of smaller aftermarket wheels. This is helpful to know for your next winter tire changeover.

"Plus size" tires mean an increased wheel diameter, which may require a wider tire as well. Make sure that your new tires and wheels are of a compatible width and can maintain the original load-carrying capacity. It's helpful to familiarize yourself with some wheel size basics.

Sometimes, customers will confuse wheel offset and backspacing for plus sizing. However, plus sizing involves the measurements of the wheel and tire themselves, as opposed to how they sit on and relate to the wheel assembly.

PROS AND CONS OF PLUS SIZING

Like any vehicle modification, changing your OE tire size to an oversized tire comes with its pros and cons.

  • Factory Size: 
    • Pros: Best for drivers seeking well-rounded performance in a variety of driving situations.
    • Cons: Drives limited to factory size settings and features.
  • Plus One (1"): 
    • Pros: Better handling and cornering.
    • Cons: Increased road noise and decreased ride quality.
  • Plus Two (2"):  
    • Pros: Aesthetically pleasing and increased responsiveness.
    • Cons: Increased road noise and decreased ride quality.
  • Plus Three (3") and above
    • Pros: Maximum style, better handling and responsiveness.
    • Cons: Significantly reduces suspension and ride quality. Potholes, curbs, snow and ice, and other hazards pose an extra risk to vehicles rolling on these larger wheels.

In sum, the benefits of big tires and wheels is mostly aesthetic appeal, improved handling, increased stability and steering response.

On the other hand, it can diminish ride comfort and increase noise. Smaller sidewalls don't absorb impacts as effectively while larger wheels tend to be heavier, decreasing fuel economy, acceleration and any road noise reduction capability.
