I don't speak inches but go with 45 profile if you are 17" that's about right. 225-235 all around? Check offsets...
Tires I personally love:
Goodyear Eagle F1 GS-D3 for the win.
Other great tires:
Yokohama Advan Neova and Michelin Pilot Sport 2 (PS2)
Price is worth it, and the GS-D3 are a killer deal, the best tires you can ride on in wet and still feel as if you are on dry... and also one of the best cornering, response, traction and grip tires for the dry you can get. I am currently running these, they are AWESOME. I blew one of them (my fault), by having some idiot deflate my rear left and driving 140/kmhr (!!!) for about 40-50km maybe more, only to realize my tire was 'deflated' (think about it... WTF?! I didn't even feel it?! It's that good a tire). Then I had it re-inflated and went to crappy tire (canadian tire) to get it fixed.. unfortunately the extensive driving damaged the tire beyond repair... but thank God my wife and I are alive... but that should tell you something how good this tire is. Currently for the moment as a spare I run a ****ty federal GT something tire (the cheapest one could get and I still got ripped off at crappy tire but I needed a tire urgently...) My point of this story is, gs-d3 = amazing in all sorts of ways AND... safe and best bang for the buck AND right now without that 4th GS-D3 and that ****ty federal tire temporarily running.. my car STILL kicks *** in corners but I can feel a difference... that crappy federal tire really sucks ***.
And that's my story
