What's Your Opion On These Wheels?
(1) Find out the weight of each RIM, and go with the lightest
(2) Stick to 20"
The bigger the diameter, the smaller the side wall, but more important the higher the PSI you will need to run. Higher PSI is going to change the quality no matter what people say...
Moving up from 19 to 20, (droping from 40 series to 35 series tires) the recommended pressure went from 35/37 to 42/44.
With a 25 series sidewall, you will probably be looking at 48-50 PSI.

What type of wheels did you go with?
Were you on the Bimmerfest with the 760? Also what size are your wheels?

Continental - 100Y front and 101Y rear. That means at max pressure (51psi) you have 1764lbs front (per tire) and 1819lbs rear (per tire) of effective load carrying. That means that at max pressure the Continentals can carry 7166lbs, that is 2701lbs MORE than the S550's curb weight is. Accounting for driver and cargo (even several hundred pounds) you will barely be exceeding 5000lbs (maybe 5500lbs with 5 people and cargo).
If you get as close to the OE load ratings as possible, you could actually bring the tire pressure down quite a bit, and possibly even at factory levels. The tire load index on my 19s exceeds my OE specs, and I keep them at near OE levels. I did put them up slightly for performance, but that is it.

Thanks, the AF144 are nasty, only issue I see with getting 21s is that the tires are a bit more expensive and hard to find.

Its a guy on bimmerfest.com with the same handle as your's and he's from Canada as well, that's why I asked. The ELT Series have some serious lips on them.
