when it come's to air in my tires i use Refrigerator air in the summer to keep the tires from expanding, and in the winter i use heated air to keep the tires for contracting ...

 

I know the wheels on the bus go 'round and 'round.

 

First you have to determine whether the pistons are going up or down...

 

What about when you are crusin' downtown, look over to the nice glass buildings, and see your reflection in the windows. When you start moving, what direction would the tires "appear" to be rotating. Probably wouldn't matter much, since you would most likely crash being as you are not looking where you are going, rather at the reflection in the window.

 

Are you looking to your right or left, need more information.

 

Crap! I forgot about that one. Well.... Lets say looking to the left...

 

I have heard a rumor that some of the 2010 models will have a front tire that rotates clockwise, while the rear tire rotates counter clockwise. That way people will not if you are coming or going. But this is just a rumor.
