a 17x8 will fit perfectly with a 245/40 or 245/45 (the latter if you want a larger diameter tire for taller effective gearing).
In 18", the tire choices kind of suck if you want wider than 225. For example, if you wanted a 245/40R18, that's bigger diameter than stock by a big margin, which is okay if you don't mind the longer gearing.
