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 may require a replacement wheel 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).
