2015 SEMA Show, Day 3: The Digital Red Book Has Reverse Lookup Tools

Order Reprints

The online version of The Ultimate Wheel & Tire Plus Sizing Guide (also known as “The Red Book”) offers reverse lookup by bolt pattern and tire size.

Joe Findeis, the guide’s creator and publisher, says the reverse lookup tools are a key advantage of the digital version.

Other interactive tools are:

* reverse lookup by wheel brand name;

* plus size tire calculator;

* minus size tire calculator; and

* wheel offset/backspace calculator.

To see how the wheel brand name lookup tool works, visit the Red Book’s website and click the “Free Wheel Lookup” button for a demo.

Both the print version of The Ultimate Wheel & Tire Plus Sizing Guide and online subscription cover tire and wheel fitments for current and vintage vehicles as well as OE and aftermarket plus sizes. But only the online version is continually updated. The printed version is updated just once a year.
