tire

Look at that bastard go! 

The sparks keep flying but he just...keeps going. Guess he really had somewhere to be?

Factory-installed braces to secure them? Not so much.

Then again, maybe you need that tire. It looks like one of your rear wheels is balding quite a bit.

Are you trying to ford the river with your Ford? I think I got dysentery just from looking at this.

"I've got the most brilliant idea! Instead of people driving on wheels, why don't we just make the roads themselves out of tires! Brilliant!"
