I have 17" AMG wheels on my '92 300D which never managed to get better than 28.5 mpg either on stock wheels or on the 225/45 17 Toyo Proxess 4 tires that were recently on it. I switched to Nokian Entyres in 225/50 17 for a 3.51% increase in rolling diameter 2 weeks ago and took a road trip from Everett WA to Portland. After correcting the odometer error for the slightly larger tires I computed 35.5mpg. Now I know that part of that 25% increase is due to the greater rolling diameter (3.51%) but I find it hard to swallow that the rest came from the lower rolling resistance of the tires. They do coast much further and the amount of accelerator pedal needed to move the car is palpably less.
