The wheel size might be stamped into the wheel.
I'm not sure its the looks so much as the function, that causes most people to swap out the wheels/tires. I have never done it for looks, but it happens to be an added perk lol. I like the fact that you can get stronger and light aftermarket wheels, with tougher and larger after tires to go with them. That's the main reason I change mine out.I think the wolverine looks to nice to keep the steel wheels on it. I'm glad they included them as it probably kept the price lower when most people are going to take these off day one and put nicer wheels and tires on.
