Hello all,
As winter is upon us in the northern US, I have swapped out my summer wheels and installed the winter wheel set up, which is: OEM style 124 wheels with Dunlop Wintersport M3s, 225 front 245 rear.
The tires themselves I highly recommend. They do well in rain, freezing rain and snow. 0-5 mph is still a chore when there is ice or wet snow, but once underway the car handles very well. 100-150lbs. of weight in the trunk (equally split over each wheel) does wonders for the 0-5 mph problem. As for performance in the dry, they are speed rated to 149 mph and although there is a little tread squirm if you start changing lanes quickly at triple digit speeds, the grip is still intact.
However, the purpose of this post is to offer this opinion: if I had to do it all over again I would get wider rear snow tires. It would help the 0-5 problem. Also, the traction light is going crazy!! The rears are far more worn down than the fronts. When going through a corner on dry or wet roads, the car will rotate mid corner and the stability control will kick in to cancel oversteer b/c the rears can't hold the corner. Personally, I prefer oversteer to understeer any day, especially in inclement conditions. But all the same, I would get 255s if I had to do it again.
Just an opinion in case anyone is contemplating snows for their 545/550.
Happy holidays,
DRP

A month ago I put the Wintersport 3D's on my 550. I also used my stock 124 wheels but went 245 40 18 all the way around.
I think a narrower tire in the snow is actually better for snow grip though.
In Chicago we have had about 3 decent snowfalls so far and the difference with these tires is simply amazing. But last winter I did limited driving with the Bridgstones RE050's and they are summer tires which were almost undrivable in snow.

Best winter setup is 225/50 17" or 245/40 18" but the tires should be Continentals.
But winter tires (and MS tires) can never be as good as summer tires, because
the winters need to get a grip on ice and that means softer tires.
The E60 is by nature a bit understeer, for safety reasons.

Well, it finally snowed here last night (on a work day), and I didn't get to try out my Dunlop 3D's....still at TireRack being analyzed for problems with either the wheels or tires I sent back. I really wished I could have tested them out, but instead got to drive my stepdad's Maxima in the white stuff...whoopie!

A wider tire will not offer more grip, it will offer less...

My understanding is that a wider tire in snow is bad in all situations except...ultra low speed straight line traction. Just like a skinny tire will better resist hydroplaning in the rain, but on wet pavement with no standing water, a wider tire will stop the car better.
