what the co2 for? and the wheel base thing and all that? All the stuff looks pretty cool.

Looks like a toy.. really. BUT all it is in reality is just a spare tire with a jack.. Seems that you inflate it with the Co2 but isnt that why your car comes with a donut anyway? This kit is useless.. that is unless you like the cool stuff.

You can tell it sucks.. just look at the words of the title: a Tune Port Injection Aluminum Spare Tire Kit

it supposed to be lighter than ur original spare or somethen?

the co2 is to inflate the tire when you need it so it takes up less room
