Small change, noticeable difference in looks.

[TrueBlue]

I have the stock 275/60R20 tires on my truck. I've been contemplating a change for awhile now. The other day I followed a late model GMC Sierra into the Home Depot parking lot to ask him what he was running on his truck, which had immediately caught my eye, and that I liked the looks of very much. His tires looked wider than mine, and lower in profile. Turned out he was running 275/55R20 tires on his. I was amazed that they looked so much different than mine. Just 1/2" shorter profile, just over 1" in total height and the same width, but it was very noticeable. Both trucks were equipped with original factory wheels. Different brand than my tires, but I think that the numbers are what tells the story, not the manufacturer/model of the tire itself. Right?

Pictures?

Tires of different brands may have different circumferences (or radius) even if they are the same size.
