I use 255/35 18's and have had 888's and now federal 595rsR's
888's where on the wheels when I got them and where great , couldn't afford them so went with federals and for 600miles I wish I'd found the extra money . Now they are very good and close to a 888 but not quit there but I can live with that at £100 a corner
Federals avalible in a 245
