He asked what was from the factory, not options for a cheaper tire

I don't understand the hatred towards runflats.
I'm sure GM's engineers took into account weight, handling characteristics, horsepower and a ton of other things into consideration when they decided runflats were the tire of choice.

I get that was 15-20 years but as of today, most, if not all BMW's come with the same runflats from the factory. I'll take the extra cost associated with getting home/to a service shop over trying to flat-deck it or hope that when I pull out my compressor the aux power still works.

What they fail to tell you is that if you drive any miles at all on a deflated runflat you will more than likely have to replace the tire. The structural integrity is gone. And since tires usually need to be replaced in pairs a simple puncture can result in the purchase of 2 new tires. This happened to my neighbor and his BMW when he ran over a nail. It was a very costly nail.
GM went with the runflat because there is no room for a spare and it's a great way to sell more tires.

I don't hate them...and if someone runs them that's cool...but, they should be aware that they are a rougher ride and are noisy as they age because they are a tougher rubber and a stiffer sidewall....with the TPMS you can monitor the pressure frequently or the TPMS will give you a heads up if you have an issue...normally a nail or some other puncture type leak can be aired up and you can continue on to a shop that can repair...blowout is a whole different deal, but that would be true for a run flat also...if the op wants to put run flats on his car... It's his car and he should do what makes him happy...I just wanted to make him aware...although he might not need it...that there are IMHO better options

Appreciate the education. If I still have the car when the next set are due, it's lookin' like I'll be saving some money.

Thanks

Humm, not my experience with my run flats. I had them replaced this year because the inside tread was cracking. They were 7 years old. I replaced them with NITTO INVO. I did not notice a difference in the ride or the tire noise between the two tire types. It was the price difference that made me buy the non run flats. Although I did by a small compressor for those times that a nail is in the tire.

I think the tire brand can make a BIG difference...see a lot of the pilot sport run flat reviews that are very positive I have done sooooo much sound deadening that shouldn't be an issue for me but, I sure like a nice smooth ride... Road condition makes a huge difference also...we have some of the crappiest roads in the country....

It's nice to finally hear cost was the major issue.

I might be wrong (I'm sure someone will point it out) but sidewall stiffness would not create more noise.

However it is true that basically driving even at low speeds for a short distances itch little to no air will toast the tire.

You could have saved us all the gloom and doom about the run flats if you would told us that earlier. Funny how far that got with a simple question.

I believe someone had questioned you on your personal experiences with these tires. Run, run as fast and far away as possible because you will devote maybe 5-10 minutes of unretrievable time trying to explain to him his beliefs aren't necessarily correct.

Not what I said. I went from run flats (7 year old GY's) to new non run flats (NITTO INVO) and did not notice any noticeable difference in ride or noise. I could not understand the complaints on the run flats since I felt they were not any different than my DD running Coopers.
