Run Flats: The Good, the Bad and Getting a Flat

I have taken many calls from people that dislike their run flat tires.  They often end up switching from them to standard tires. 

These are the main issues people have with them:
  • They cost more
  • Their ride quality is harsher
  • They wear out faster
  • They are louder
My BMW 335i came with the the Bridgestone RE050A run flat tires on my 18" factory wheels.  When I opted for my aftermarket 19" wheels I went with standard tires, the Sumitomo HTR ZIII.  Even though my sidewall height is less, the ride quality has not been affected.  I also noticed that the temporary flat-spotting I had with the run flats is now gone.

To allow myself to sleep better at night, I purchased our ContiComfortKit in case I get a flat.  After over 2 years of use, I have yet to have one.

RFTs are complete crap. They cost 2x as much and last 1/2 as long, thus real cost is 4x. Ride quality is horrific. Replaced with GFTs (regular "go flats) and ride is much better, no road noise, and handling is at least 50% improved.

I replaced the standard Bridgestone run flats on my 2006 BMW 330xi with non-run flat Michelins. The difference is so dramatic it is disconcerting. Silky smooth and quiet. No ridiculous rock hard bottoming out on any mild road bump. It is a dramatically improved vehicle. Now a pleasure when before a disappointment. I have bght Conticomfortkit for the trunk and my BMW protection card and AAA if I ever get a flat. Which ,by the way, I have not had on any of my vehicles for over 200,000 miles. So, I've traded that risk for an awesome ride.

I would like to get a better ride and save money by getting non-run flats on my 2009 335i xdrive. However, my dealer says I can't because the wheels are designed specifically for run flat tires. Any suggestions?

I have a Honda Odyssey touring with run flats and I can't stand them. Is there any evidence that these tires preform worse in weather, esp. snowy conditions? In order for me to change the run flats, I have to change the wheels and then...I have problems with the tire pressure censore working properly. Can you rec'd a wheel & tire combination I might use, if I do change them out?

I am considering replacing my PAX tires are there any wheels and tires now available for my 2007 Odyssey touring?

I'l like to replace Run-Flat tires on my 2004 Toyota Sienna XLE LTD, with non-run flat tires. Do I have to have Run-Flat tires only for this vichicle?
