Tires for 2007 E320 BlueTec?
The 2007 E-Class brochure lists the standard tire size for the E320 BlueTec as 255/55 R16. Wheel size is 8 x 16 (same wheel as 2005/6). I can't find any such size tire. The tire size for 2005/6 is 225/55 R16.
I believe the brochure is incorrect, and that the "255" is a typo. Does anybody know anything to the contrary?

Agree with MagicO309D; it is almost certainly a typo. The car will likely come fitted with 225/55-16 tires, same as any other W211 with the basic 16 inch tires/rim combo. There is a good reason for this. The car will likely come fitted with Michelin or Continental all-season tires that are lower rolling resistance than summer tires, or than the wider 17 inch tires. If you are buying a diesel, you are assumed to want to maximize fuel efficiency.

In this link, the author notes that the "Bridgestone B381 ... has a measured rolling-resistance coefficient (RRC) of 0.0062 (2002)—one of the lowest on the market. The Michelin Pilot Sport A/S ... has a rolling-resistance coefficient of 0.0133 (2002)—one of the highest." http://www.hybridcars.com/blogs/hyview/tire-labels
I was looking at the spec as I've been contemplating 17" or 18" wheels and a better handling tire for the "good weather months" and using the 16" stock wheels for snows for winter driving. Rolling resistance is something that the manufacturers generally do not report.

The standard 16" tires on the CDI are absolutely awful. They make the ride floaty and handling borderline unsafe. I put on a set of 18" W211 sport package wheels/tires (245F/265R), and the car was transformed. It's no BMW, but there's now just enough starch in the ride to know what's going on under the car, and on/off ramps can be taken without feeling like the car is being tortured. Mileage doesn't appear to have suffered.
