[W126 Coupe] wheel and tire size

[jflyer2 at aim.com]

I forgot to mention that the 17 x 10s were used on the rear. I think the widebody coupes used 9" front and 11"? rear.

Jono's right. If AMG had felt that 18"s were a good match for the W126 MB's suspension geometry, they would have sold them. Their max was 17" with a width of 10" IIRC.
I have 3 pc.17 x 8.5 AMGs with 245/45/17 W rated rubber. Improvement in handling and looks is great. The ride is a little harsher on the city streets but can be lived with. IMHO, 18"s make the cars ride like trucks.

I run 17's w/ either HD's or AMG spec bilsteins all around. 18's weigh too much IMO for the suspension to Really work ie, an 18 X 8 Aero II Monoblock comes in @ 54 lbs w/ rubber...while the 17 is almost 10lbs lighter.?

As mentioned prior, the tyre you run will have a Huge effect on how the car rides..I run H rated on most of my street cars and w/ the 17 the degradation in ride quality is essentially nill while the improvement in handling is monumental.?
?
A number of magazines have done tests (Grassroots Motorsports the most recent that I can think of) where they test the handling w/ plus size wheels/tyres. Typically the consensus is one will do best w/ a +2 over what the OEM sold the car with, ie a 17 in this case. AMG seemed to be of the same opinion as 17 was the largest wheel they offered.?
?
I run 17's on the track and scare the Hell out of the BMW guys as they all think I'm going to shoot off the road;-)?
