The different Proline Compounds?
 

Hello everybody,
i was out of the Hobby for a couple of years now and cant find any informations about the newer Compounds of the Proline Tires.
Can someone please explain the difference between M, X and S Compound? How do they compare to each other?
Last time i was racing there where only M2, M3, M4 and XTR Compound.

Take this with a grain of salt, as this is off the top of my head so I may be wrong on a few points. I'll list below:

Numbers: You probably know this, but I'll explain. The #'s on the rubbers is the atmosphere you're going to run on. 2 = hard all the way to 4 = SuperSoft
M - Is their OUTDOOR rubbers.
MC - Indoor or Clay rubbers
MX - Soft tire for very hot days outside
X - These rubbers are more for open tracks with more straight shots.
Z - Just indoor rubbers from what I know
G - These tires tend to be more nobby and are used for climbing, bashing or just rough terrain (gravel, sticks, etc)

That's about all I know on their tires.
