I've ran the VW tires. Honestly it was because they were given to me. Bit small for most cars.
Sammy is giving you good advice on the 6.40x15. When your tires are scraping and rubbing, it takes a bit of the fun out of your ride. I'm a glutton for punishment though . I run 8" wheels on my 65 Chevelle which is tough on the early A-body. If you go any bigger on your Camaro you'll have to remove the 12 o'clock fender bolt for the wheel well- at a minimum. I do like that oversized tire look!
