James,
Larger wheels are GREAT.
You have to decide how you want the car to look.
I almost changed to the Hot Rod look. Maybe another car,the wife will kill me.
I liked Ron Mast red spoked wheels but just wanted a larger diamenter.
I already had 600/650 x 18 on my truck so knew the drove great.
Rally America 18" wheels, 4lug, 600/650x18 Firestone from Coker
This is a picture of the truck and the car with the orignal wheels
Weather was nice yesterday, had them both out for a drive.
Rain and 48 today, got to enjoy the day when you get them.
