Small change, noticeable difference in looks.

TrueBlue · May 28

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?

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

No pictures.

Possible that the brand could make a difference, though I've always thought the numbers tell the story. All I know for sure is that his tires sure looked good.

Some tires have more tread depth thus a different circumference. Tread depth will vary by type, brand, and model.

You should not mix tires in any way on an AWD (all-wheel drive) or 4WD (four-wheel drive) vehicle. If you drive a 4WD or AWD, your tires should match in tread depth, brand, model and size. Mixing tires in any way on these types of vehicles can cause wear and/or damage to the vehicle's drive train.
