On my 17's i had 4 205/40/17 they were pirelli P zero nero's , they were a very good tyre, I'm was suprised to say the least,very very grippy on tarmac and not too bad in the wet either, i picked them up from my local garage for £75
each ,thats icluding balancing and fitting!
F1's are very overpriced imo, falkens havn't impressed me much in the past and i'v never used toyos(yet). I see it as less tyre fold on 205's but others see it as more grip surface on 215's
iv'e just ordered new alloys with parada spec 2's , meant to be really good tyre aswel but i'll find out soon!
