Just got my first mustang. 2012 V6 Premium w/Pony pkg. Has no spare....done got the scoop on that. Has the Pirelli tires with GREEN Caps. Nowhere does the paperwork or books say what is in the tires. The dealer did not even know. Should I assume that since the caps are green that the tires are inflated with nitrogen?

 

Even so you shouldnt have any issue topping them if with air...if that is your question. I personally think nitrogen is a bit gimmiky

 

The green should represent a nitrogen filled tire. however no spare? does it have room as if there was a spare? maybe the dealer stole it haha jk
