Well, yes, the stock Bridgestone's are crap but that doesn't mean all bridgestone's are.. some of the best tires you can buy are bridgestones (Potenza S-03) .. I would recommend the Bridgestone Potenza RE730's if you're looking at the Firehawk SZ50's ... similar price range with a proven track record and darn good performance for the $$ .. a good number of people have used them on their 'ludes (myself included

) and they're recommended by a range of people from 'luders to folks with Supras.. can't really go wrong.
Only thing is that most people seem to have a problem with road noise on them after awhile.
