Re: [MBZ] Wheel/tire sizes?
Is there a label on the body somewhere that tells you the original tire sizes?

Yeah that’s kinda weird that a tire shop would have done that. I wonder if these wheels are actually staggered (and I think they might be) so shortening the sidewalls by pushing them out actually makes them shorter such that the overall diameters are the same.

Re: [MBZ] Wheel/tire sizes?
This is not unlike the conundrum that my recently acquired AMG chrome staggered monoblocks have presented: They (as in all four) have 245/45 tires on them, despite being 8.5” on the fronts and 9.5” on the rears. And I have verified that they are, in fact, different pairs of wheels.

[MBZ] Wheel/tire sizes?
On this 07E350 it appears to have staggered wheels (I have not pulled any off to see the exact sizes) with tires the following sizes: F 265/35ZR18 97Y R 285/35ZR18 97Y On my other cars (CL500, CL600) with staggered wheels I have F 245/45 ZR18 96Y. R 275/40 ZR18 99Y which makes sense as the first number is width and the second number is profile (height of tire as % of width) which keeps the total diameters and tires circumferences the same between front and rear. The sizes on the E350 puzzle me as it would appear the rear sidewalls (285x.35=99.75mm) are slightly larger than the fronts (265x.35=92.75mm). Overall diameters are (18x25.4)+(2xSidewall) == 457.2+R199.5 (or F185.5) = R656.7 (or F642.7) for circumferences of R2063 (F2019) which is ~2.2% higher R than F, which would drive the wheel speed sensors crazy.
