Nope, all E60 cars can be fitted with 16" wheels (per TireRack), SP or not, I6 or V8, it makes no matter. That said, the situation is very much like that of my old E39, while there were 16" wheels that would fit, they were very few and far between.

Remember the good old days, when 14" wheels were an upgrade?

Yeah, I was so proud the first time I bought a car with 15" wheels.

>"That said, he already has a set of winter tires in the stock 535 size.. I'd just get wheels for them, and be done with it."
 
I'm trying to find out how much better the traction would be between 16 and 17.. probably tough to measure. Since I already have the 17s it makes sense to go with those, but since I'll have the car for many years I don't want to have worse traction every year just to save a few bucks on the tires this year.
 
>"I'd double check the 16" thing with a phone call.."
 
BMW lists 16 inch tires on the accessory page for the 2008 535i (star spoke 115), but you're right - better safe than sorry.

Assuming the same section width (i.e. 225), probably impossible to measure. I've never seen any compelling evidence that proves that a winter tire of any given width and diameter will perform better if the wheel is smaller.

My mistake - I was confusing the aspect ratio with the tire width.
 
So, given that the 16 and 17 have the same width (therefore the same traction as well), would there be any major reason to go with the 16 other than cost?

Assuming the 16" tires are sized properly, they'll be the same overall height... With 1" less wheel, the sidewall will be 0.5" taller than the corresponding 17" tire.
 
If you have bad potholes, or your spouse is maybe not as careful as you would like, then you do have a small amount of increased protection from pothole damage.
 
But, traction/winter handling improvements would probably be too small to calculate.
 
If you stick with 17" wheels, you'll have a lot more choices... Personally, I like my car to look just as good in the winter as the rest of the year, which is why I don't like to downsize... (but, that's just me).

EDIT: Some people think that extra 1/2" of sidewall lets the tire flex more, and find better tracton in deep snow.. Not sure that makes sense to me, but there you have it.

Good info - thanks. Since I already have 225/50 17 tires, I guess I'll stick with those and pickup some wheels.

...at the BMW CCA Oktoberfest in Fort Worth. Great engine; lots of torque and relatively free of compression ignition rattle. I would have liked a stick but the slushbox did pretty well. The rest of the car was okay, but not really my thing. It was a european SP which had several new/unique features. The HUD worked well, but didn't supply enough info. The car also had the lane departure warning system; I guess Munich wants to attract some customers from God's waiting rooms at Cadillac and Lincoln dealerships. The handling was above average, though I still don't care for BMW's Active Steering. The SP run flats were noticeably more harsh in terms of bump/thump when compared to the 21" go flats on my B7 loaner. Go figure...
On the diesel evaluation sheet I stated:
"Put this motor in a 3er coupe with the European M Sport package and I will buy one. Put it in a 1er M Sport 5 door hatch and I'll buy two."

Wow!! Great idea!!! Will do that next time for sure. I actually ended up going with the E350 and added the AMG rims for $2000.00
 
I still think the 535xi is a better car, but I need something for weekly driving as I am putting to many miles on my M35x. The E 350 4 matic will be my commuter car and the M35x wil be my weekend car. The 535xi performed as well as my M35x, so I decided to go with something less powerful with better gas mileage.
 
Thank You again for your advice.
