Thanks for the response. The calculated height for a 225/60/15 tire is actually 25.63 inches. This, of course, will vary slightly from manufacturer to manufacturer. A 225/50/16 tire has a calculated height of 24.85 inches. This is considerably different than the stock height. To get the stock tires height on a 16" wheel, I need to go with a 225/55/16 (25.74" tall) or a 245/50/16 (25.64" tall). I'm a little wary of going with a 245 wide tire as that is close to an inch wider than the stock tire. I'm afraid it will rub on the inner fender. If someone can tell me that it won't rub, I will go with the 245/50/16...otherwise I'll go with a 225/55/16. It sounds like you're telling me that I can go with 245s without any problem, though. I'm planning on going with the Yokohama AVS db decibels or possibly the Yokohama AVS Intermediates. I'm also considering a few other tires, but those two are at the top of my list.

I'm not sure what the offset of my BBS wheels are. I guess maybe I should measure one before ordering tires. The guy at Discount Tire thought that the front wheels looked like they have a different offset than the back wheels. The car came with two extra wheels, even. :) The wheels are black cross spokes with a polished lip. IMO, they look pretty good with the charcoal gray paint on the body.

If you're interested in seeing the the ground effects, I'll take some pictures with my digital camera here in the next couple of days. I'm not sure how to post them, but I'll email them to you and you can post them if you want.

Thanks again for your help!
