Saying SF roads are B+ is also a stretch, as they suck pretty bad in SF proper. The highways are OK, but if you spend much time in the city - be cautious about going with the 20's.

I am pretty sure that the OD of all the tire offerings is the same...hence an OE 20" will have the same outer diameters at the OE 19"...which would mean only one spare tire is needed, or your spare should work for both.

Check for yourself- go to tirerack and look up both TIRES and see what the spec is for OD.

Of course, TREAD is a different story, but with a spare you are going no more that 40 miles at 40MPH, right?

Yep in SF and in CA in general, road quality can vary greatly. There are a lot of stretches that are quite poor.

I had a dealer comment yesterday that he would be very careful about putting non run flats on an X5, because the X5 and its suspension was designed for hard side walls not soft. He thought that it would make the care feel mushy. Granted this is just his opinion, but he is probably the most technically sound dealer of about 5-10 that I have talked to in the last 3 months.

I am curious what opinions are on this here. I had been pretty set on putting non-run flats on regardless of the size, but now I am thinking about it a bit. I think ARD has said the that he Michelin latitude run flats are actually pretty good.

I changed to non-RFT's the ride softened a bit after the Michelin's that came stock, but I got the spare tire intentionally so I could ditch RFT's. I will say that I anticipate AD to be a better option with non-RFT's than stock suspension. Stock suspension didn't seem to wallow, but not as harsh, and not quite as "planted" as the RFT's (I think the "planted" feeling was a byproduct of the harshness though. 20's and AD are perfect, but I think non-RFT's will still be in my future. Had a 335i with RFT's, my m3 doesn't, and the m3 suspension actually feels less harsh over rough roads. Same with the X5 and RFT's being extremely harsh over rough roads - drove a LOT in OK, some of the worst roads in America, and AD made me instantly thankful.

I have the 20"'s on my X5 and just switched to the non-RFT continental extreme contacts. Greatest improvement in drive I've ever seen. Would recommend them highly.

So, I am guessing they are smoother? Any drop-off in handling?

also, there are no staggered 20 inch RFT all season that i know of. If there were, it would save me 2 hours at Direct Tire. I personally use the Dunlops in the warmer months and Perelli Scorpion Ice and Snows in the winter months on the same rim.
