I've decided to go with 18's on my car. The only size the wheels come in that I'm buying are 18x7.5 with a 45+ offset. Is this gonna fit properly on a Max? I'll be putting H&R sports on it as well.

Now as for tire size...

235/40/18 or 225/40/18

Adam has 225/40/18 on 18's. Will the 235/40/18's look to big? I've seen some cars that look like freakin' ballon tires on them. I kind of want to avoid that.
