i had this issue with my 'ring taxi. as it is registered in germany and has standard wheels, it must have the original size tyres or you get into all sorts of certification issues

we chose to go with some fulda's in the end (can't remember which model exactly, but they were directional) and during 18 laps of the 'ring in both wet and dry conditions i couldn't fault them really for the cost.

ok, maybe others would give more ultimate cornering grip, but is that really that important in day to day driving? i am a firm believer that tyres are the most important safety factor on a car when it comes to an incident, but as there is no real evidence on what works best on your particular car and road surface, you can only go with something that you believe to be good enough.

my mate had the fulda's on the front of his tvr griffith (same size) but recently replaced them with toyo's. impossible to see any differences though, as he also replaced all the suspension with adjustable stuff at the same time.
