Kumhos are a great buy, as long as it is dry. My friends M3 with Kumhos will swap ends nothing flat when it gets a little wet.

I talked to a tire engineer and this is the reason he gave me.

Kumho use a lot of polyester(sp?) in their tread because it is very inexpensive but has very good durability and heat disapation.

Better tires and more expensive performance tire will use Rayon instead. Better characterists dry or wet, but the material costs way more. Better "plyability" if that is even a word, when it comes to how the rubber is combined with the Rayon itself.

So, with that said, generally Cobra's have 90" wheel bases and can swap ends pretty quickly if not paying attention.(Like I need to tell anyone that one on this board.) But most of the time these cars are not driven when its wet, so you can be the judge.
