Also OP, if you want to know what a tire size means, it's in millimeters. The first number is the width, the second is the aspect ration (the thickness of the sidewall as a percentage of the width) and the last one is the rim size.
275/55/20 is 275mm wide with a .55x275mm thick sidewall.
You can convert to inches and add the rim size to 2x the thickness of the sidewall to figure out tire height and width, but I just use the tire size calculator I posted cause it's easy and I hate math
