INCH UP
Plus Zero
utilizes the same wheel diameter as the OE tyre but combines it with a tyre which has a larger section width and a smaller aspect ratio than the OE tyre. For example, replacing an OE 225/50R17 tire with a 235/45R17 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.
Plus One
utilizes a one-inch larger diameter wheel in comination with the tyre which has a one-step lower aspect ratio than the OE tyre. For example, Plus One fitment is to replace an OE 225/50R17 tire with a 235/45R18 tire. Note that this method always requires a replacement wheel.
Plus Two
utilizes a two-inch larger diameter wheel in combination with the tyre which has a two-step lower aspect ratio than the OE tyre. Plus Two fitment is to replace an OE 225/50R17 tire with a 255/35R19 tire.
