My idea of a good time on Black Friday? Playing with black tires in my shop of course.

After a 2,500 mile break-in, the 285/75R17 Cooper Discoverer S/T MAXX on 2016 Ram Power Wagon WFV wheels were removed. They were replaced with 295/70R18 S/T MAXX on forged WBJ OE 18-inch wheels.

Aside from the wheel diameters, these tires and wheels are very similar. However, there is a noticeable and measurable height and width difference, the 295s being both a bit wider and taller.

Multi-tread and width tests are underway for future editorials.
