The typical run-flat is designed with extra-rigid sidewalls to enable the tire to still be driveable without air. As a consequence, I've read that the tires do not offer as much shock-absorption, and can produce a harsh ride. Additionally, the tires are relatively heavy, undesirably increasing unsprung weight. Replacement in the event of a flat can be problematic (since one never has a flat at a convenient place, like in front of the dealer.)
 
If you haven't noticed, I'd suggest you continue to enjoy your 545, but to be honest, I think a limited service spare might be the way to go these days. Both my E34 and E39 have full-service spares that have seen very "limited service".
 
Here's a link to an Edmunds discussion of pro's and cons:

In addition to reading the article that sdg380 linked for you, you might want to read some 3-Series owners' real-life experiences: BMW 3-Series Run Flat Tires. At least a couple of regular posters have replaced their RFTs with regular tires (which we've nicknamed Go Flats, i.e. GFTs).

I still have my RFT in my car with 25K miles, and a I also have a spare tire that I bought from Tire-rack in my garage. I usually toss the spare tire in the car when I embark on long road trips.
I have had two punctures with my RFT and have been able to get them repaired. The key is not letting the tire pressure fall below 18 psi at which point you will start loading the side wall.
The RFT in both cases allowed me to drive home safely and change the punctured tire.
 
I have to admit that due to stiff side-wall, you get a harsher ride, however I have also noticed maintaining 2-3psi above the recommended tire pressure improves the ride quality. Increasing the pressure a little bit reduces the load stress on the side wall when you take those little bumps or pot holes.
 
I intend on getting the 535i, and I will without a second thought opt for RFT because of the safety factor.
 
Just thought I should share my experience.

More info re rear side airbags in the 5 series: I contacted BMW of North America about this and they said that a child properly restrained in a car seat would be okay, but many children fall asleep or lean against the door and would be in danger.
 
Here is the text of the follow-up e-mail:
 
Thank you for contacting BMW of North America, LLC regarding the rear-side airbags in the vehicle. We appreciate your inquiry.
 
Passengers are safer with rear-seat side impact airbags than without them. Children must be properly positioned and restrained to ensure their safety and avoid possible injury from airbag deployment. Please see your Owner's Manual and the in-vehicle safety tips card to ensure proper positioning and restraint.
 
For vehicles equipped with side airbags, all occupants should be properly restrained - children in appropriate child restraint systems: larger children and adults using the safety belt - and sitting upright. Never let an occupant's head rest on, or near any side airbag. If this warning is not heeded, the inflating side airbag could cause a serious or fatal injury.
 
We believe the safest place for children in an automobile is in the rear seat. However, a child sitting in the rear seat and not properly restrained in a child seat appropriate for their size and age may place his or her head on or near the side airbag. For example, a child, even though belted, may fall asleep with his or her head against the side airbag or may lean out of the child seat in the direction of the door. It may be difficult for a driver to ensure belted children in the rear seat will remain properly positioned at all times and not place their heads on or near the side airbag. Therefore, we recommend that you deactivate the rear-seat side airbags if you plan to transport children not properly restrained in approved child seats or in the rear seat of your BMW.
 
BMW of North America, LLC will provide rear-seat side impact airbag deactivation free of charge. If you are interested in deactivation, please contact the service team at your authorized BMW center.
 
You may read more about airbags by accessing the National Highway Traffic Safety Administration's (NHTSA) website www.nhtsa.dot.gov, or you may call them at 800-424-9393.
 
If you have any further questions, please respond to this e-mail or contact the Customer Relations and Services Department at 1-800-831-1117, Monday through Friday from 9:00 A.M. to 9:00 P.M., Eastern Standard Time. Again, thank you for contacting BMW.

Thinking about purchasing a BMW 5 Series by mstlc

I currently drive a '04 ML-350 and have been researching the '08 BMW 5-Series. I've test driven the 5-Series on 3 seperate occassions but can't decide if I should or will be comfortable going from a SUV to a sedan. I went to a dealership yesterday and got what I think is a good price quote on ordering a 535i pretty much fully loaded....xxx above invoice.
 Does anyone have any comments/suggestions?

What we used to call the "station wagon" in the U.S. A very competent variant of the 5-Series if you need the stowage space and want the performance of a sedan!

I'm driving the ML because it sits high and I"m petite; storage and space isn't really an issue. Several people I have told me that I'm not going to like driving the sedan after driving the SUV.

Well, you said you drove the 5-series on 3 occasions. Were you comfortable driving it or not? That's your answer.
