I have a 09 r/t with the 19" wheels. After replacing the tires off and on over the last two years, I purchased some 17" rims from Discount Tire (17" chrome $167 ea.) and tires (65,000 mile/ $103ea.) The last 255/55/19 cost me $279. I think I'm better off with the 17". At least If the wife has a flat I can pick up a spare just about anywhere. The ride is more comfortable.
