sizing up my wheels.
 

I have a 2006 Accord EX V6 Coupe. The current wheels are 17"x6.5" (I think 215, 70, R17). I'm looking for a wheel upgrade, and want to put a little more rubber on the road for handeling. Was thinking at 18"x8" wheel? and maybe to a 235, 45, R18. Will this size work without rubbing?
Are after market rims as well made and tough as stock rims?? Hate to be bookin at 150mph and have something go bad.

Might check out tirerack dot com and see what they have......and just me - old fart - 150 mph, I hope this is on a track.
