I have some questions about Grabbers not meeting the C rating (or D).... That extra sidewall reinforcement is important.
No one replying seems to be concerned about this, or at least talking about it. Did I miss something over the years and are folks OK with this ? Is the 100 rating now OK ?

Just curious, not trying to steal the thread.- Sean G87 Syncro Tin Top, Subie 2.5, 15 inch rims :-)

50 is too much since the max. on sidewall is 50, if you put 50psi then
there's no room left for expansion when the tires get hot.
