Unidirectional.........how important.
I have 24500 miles on my stock tires, wearing pretty well with minor exceptions. I'm guessing about 3k left max. Service dept guy said the car, with it's suspension, is designed more for unidirectional tires.
any truth to this and something I have to consider?
all this talk of the Pirellis PZero got my interest.
thanks

well your stock tires are unidirectional tires, and given that *most* of the high performance street tires today are unidirectional tires, he's probably just referring to that fact. I can't think of how suspension setup can directly affect which type of tread its tires must use.
Pirelli PZeros are excellent tires, unidirectionals too!

I think the service guy was just talking out his behind.
You certainly do not need unidirectional tires, and there are many high performance tires that aren't unidirectional. I know the Pilot Sports I had on my 8 weren't and the Potenza RE070s that are on our STi aren't either. Both are very grippy, moreso than the stock RE040s.
If you're looking for new tires I wouldn't even bother looking for that "feature" (if you want to even call it a feature), just look for what grips well within your price range.

Directional tires are only directional in order to channel rain properly. If used in the dry it makes no difference what orientation they're in.

Well,
1) The guy probably doesn't know what he's talking about.
2) Asymmetrical tires very often require less toe-in than (symmetrical) directional tires as they tend to move towards the cars center 'all by themselves'. Apart from that, #1 applies.
