spare

i mean it is one of the most over looked wheel out of the whole bunch right

when you most need and it'll fail if you haven't replaced it with a new fresh tire when your old one is old...

i already know most of yall took it out and replaced it with your audio stuff just for more room...

 

not sure when you would need to replace it, but you can install a spare tire check/fill hose that makes it easy to check pressure and fill when you are checking your other tires. at least you'll know that its not flat or loosing too much pressure over time.
