school me on the stock TC tires.
 

I have purchased a 2013 TC . i read alot about the tires. why are the stockers no good and what are good tires ?

I searched and found just a few issues regarding the 49 PSI rear pressure and some durability issues with Continentals. Some discussion here, you can search for more by checking other threads here. Post 8 IIRC:
