bandwagon, thanks.

Since my 135s are still good I'm just on a tire hunt. Turns out the M235 in the Star BMW PSS has standard load tires front and extra load (xl) tires rear, but runs extra load front and rear in the Michelin PS4 and other brands. Not sure I get why the difference. Anyway, per Tire Rack the ZHP runs extra load tires front and rear.
