One of the easiest ways to improve the performance of your vehicle is with Plus Sizing wheels and tires. Plus Sizing refers to tires that are wider and have a shorter sidewall. The result is a larger contact patch and a sportier look.
What's "Inch Up"?
"Inch Up" is the process of mounting a lower aspect ratio tire and larger diameter wheel on your car. This effect creates a larger contact patch and a shorter sidewall.
Drivers choose Plus Sizing to improve:
- Steering response
- Cornering ability
- The look of your vehicle
Why "Inch Up"?
"Inch Up" to improve your vehicle's performance and appearance.
- Increased steering response
- Improved dry handling
- Enhanced cornering ability
- Aggressive good looks
How Can You "Inch Up"?
"Inch Up" with the experts in plus sizing.
- Innovative technology
- Precision fit
- Wide size selection
- Proven performance
"Inch Up" may be done in several ways.
The most popular methods are:
1. Plus Zero
This method utilizes the same wheel diameter as Original Equipment (OE) but incorporates a tire with a larger than OE section width and smaller than OE aspect ratio. For example, replacing an OE 175/70R14 tire (on a 5.5-inch wheel) with a 195/60R14 tire would be a proper Plus Zero fitment. Note that this practice may require a replacement wheel in order to maintain proper rim width for the new tire.
2. Plus One
This method utilizes a one-inch larger diameter wheel in conjunction with a tire of a one-step lower aspect ratio. An example of an appropriate Plus One fitment is to replace an OE 175/70R13 tire (23-inch overall diameter) with a 185/60R14 tire (22.9-inch overall diameter). Note that this method always requires a replacement wheel.
3. Plus Two
This method utilizes a two-inch larger diameter wheel in conjunction with a tire of a two-step lower aspect ratio. An example of an appropriate Plus Two fitment is to replace an OE 175/70R13 tire (23-inch overall diameter) with a 195/50R15 tire (22.8-inch overall diameter).
The offset of a wheel is the distance from its hub mounting surface to the centerline of the wheel. The offset can be one of three types.
The hub mounting surface is even with the centerline of the wheel.
The hub mounting surface is toward the front--or, wheel side--of the wheel. Positive offset wheels are generally found on front-wheel drive cars and newer rear drive cars.
The hub mounting surface is toward the back or brake side of the wheels' centerline. "Deep dish" wheels are typically a negative offset.
If the offset of the wheel is not correct for the car, the handling can be adversely affected. When the width of the wheel changes, the offset also changes numerically. If the offset were to stay the same while you added width, the additional width would be split evenly between the inside and outside. For most cars, this won't work correctly. We have test-fitted thousands of different vehicles for proper fitment. Our extensive database allows our sales staff to offer you the perfect fit for your vehicle.
