The wheel is super dependant on personal preference, so it's hard for me to make a suggestion. My best advice in this scenario is consider the diameter with your budget. A stock size tire (235/40/18) is going to be much more expensive than a similar size tire on a 17" wheel, since a ratio of 40 on an 18" is considered low profile, but a ratio of 40 on a 17" tire is not. As far as tire brands are concerned, the Continental ExtremeContact is a great performing midpriced tire. The Michelin pilot sport 4 is a bit more expensive and slightly better than the Continental. I've heard nothing but good reviews about the Firehawk Indy 500 as a low budget summer tire, but I can't personally vouch for it.
