2007 Mercedes E550
Using your own calculations and not the calculations based on the tire aspect ratio and rim size, you are still incorrect. His speedometer would be reading faster and not slower as you stated. It would be reading 60.44 since the newer tires rotate 5 more revolutions per mile, according to your figures, and thus would cause the speedometer to read faster than he was actually traveling and not slower.
With all that said, .73% is well within the manufacturers guidelines so you really have nothing to worry about. It was a moot point that was based on the calculations of the aspect ratio and rims and not the manufacturers specs. It has persuaded me, for the time, not to put 22" rims on my GL. I would be worried that the rims would be damaged too often with such a heavy vehicle and a low aspect ratio. AMG got it right with the 21's.
You car does look sweet. Keep us informed of any bent or broken rims.

They look sweet. If they bend, get another rim. I'm just interested to see if they do get bent. If not, I'll probably get 22's or wait until the AMG 21's are readily available at reasonable prices for a cast wheel and not the crazy high prices people are asking.

According to the Tire rack, his OEM tires were 275/55/19 Continental 4x4 Contact that do 721 revs per mile. The General UHP do 660 revs per mile. That's a wee bit more than 3%. Ouch!
Leo taught me not to rely on the manufacturers sizes, aspect ratio and rim size, to determine the actual size of the tire.

Ouch
My wife is typically at or under the speed limit...lol Interesting to know about the 3-4% for when we drive to CA and I set the cruise to 84mph (when we are really going 87). Thanks for the heads up---I would've thought the speedometer would be set with tire inputs in this day and age....but what do I know.
