#1138 of 3108 You Saved me big time.....
Jul 15, 2007 (4:09 pm)
My wife has had 3 3X series and I was contemplating a new 328xi acquisition from BMW Peabody MA.
When I saw the car didn't have a spare, and they claimed Run Time Spare was the new technolgy I got nervous and curious and did my research on the Web.
Thank you all I found you, and your comments, obviously I will not be pursuing my purchase towards the 328xi. Had I not found this Web page I would have go on and make the same decision you all did.
I am in high tech sales myself I think the RTS is ahead of its time and the infrastructure to support it its not there yet, this car is for my wife and I just can't feel comfortable without a spare.
I believe BMW gambled that the 3 series is/was so popular that they took a gamble on this technology.
Thanks again to all, you sure saved me a lot af aggravation.... good luck on your tire/dealer engagements...

Ummm, please tell us, what did your Web research tell you about a "Run Time Spare"?
FWIW, I've been a fan and driver of BMWs for years and I have yet to hear of this new technology that you speak of. I'd love to know before I make the same mistake of buying a 328i.

On paper RTS looks and sounds great...but the reality is different from what you can read from the people on this page who actually have lived thru somne of the issues and experiences of BMW 3 RTS.
Let me see if I ca summarize what I read:
-Sound problems with the tires.
-low life cycle just 15K or less miles,
-no repair buy a new one if damaged,
-few places can replace such tires
-special machines and training are necessary , if stuck in the middle of nowwhere you can't find such tires.
-Problems in dealing with tire manufacturers abd BMW dealers.
-EXPENSIVE proposition in replacing the tires.
Maybe I missed my readings but all these factors make me say bye bye to BMW until they solve these problems.
In my mind from what I read about RTS is NOT worth at all on the benefits against the risks/expenses.
My wife has had 3 3 series and me 3 7 series
but this RTS technology is just too much to swallow I just don't see the risk/reward equation.
I would never feel comfortable in taking a trip even from Boston to New York thinking what would happen if something goes wrong on I84. Imagine if you are in Texas going from Houston to El Paso and the light saying you have 50 miles of life at 50MPH is on....
I will never subscribe to that, I think again BMW gambled on a technology ahead of its time, RTS and that technology need the US infrastructure to be ready for it (garages, inventory, know how) and today is not there, however I believe 10 years from now everything will be in place.
On the other hand like us you say 90% of the time you are in a Metropolitan area like Boston area, but why even gamble with that 10% when you decide to go to a remote lake location and should something happen go thru the horror stories you will find on this Web page, without even considering the noise and performace issues.
In my own opinion, that is a risk I am not willing to take.
Good luck in your decision, and thanks again for your feedback.

Ummm, okay, now I need to give you some more feedback.
1) There is no such a thing as RTS, period, full stop, the end.
2) What BMW is using on all 3-Series cars and most (but not all) 5-Series cars is a technology called Run Flat Tires (RFTs for short).
3) Some of the folks who have opted for a Sport Package version of the cars have complained of a harsher ride but seemingly not all.
4) There is zero evidence to suggest that the summer performance RFTs that come on SP equipped cars have a shorter lifespan than the similarly sized and endowed GFTs of previous generation BMWs.
5) The folks who have non-SP equipped cars seem to have universally complained about many aspects of the original Bridgestone All-Season RFTs, that said, Continental RFTs seem to be much better received and the jury is still out on the allegedly revised All-Season Bridgestones.
6) By all accounts, the All-Season Continental RFTs are good for an easy 30,000 to 40,000 miles, far beyond the 15,000 miles you state.
7) There is no special training required to mount an RFT on a BMW rim as compared to the training required to mount a GFT on the same rim. Said another way, any place capable of mounting a tire on a BMW rim can mount an RFT on the same rim and NO special machines or training are required.
8) Contrary to what you may have heard, RFTs can be repaired in the same manner as GFTs, assuming of course you don't drive too far on the tire with the low pressure.
9) I make the trip between Boston and New York many times per year and I agree with you that I wouldn't want to make that run with only four RFTs between me and a tire problem. That said, if I was to opt for a 3-Series BMW I'd immediately change the tires out for a set of four conventional GFTs and then buy a can of "Spare Tire in a Can" or other flat tire repair aerosol. Should a flat tire occur, I'd use the can and then have the tire either fixed or replaced.
10) Instead of a 3-Series you might want to consider a 5-Series, that car was designed before BMW started using RFTs and still sports a spare tire well and even a spare tire from the factory.
As a suggestion, before you decide what risks you are willing to take, you might want to make sure your facts are correct first.

Jul 15, 2007 (6:53 pm)
Thanks for your feedback and for correcting me on the RTF nomenclature, but you forgot to address several key issues.
-BIG price differential of the RTF tires vs normal tires.
-Change tires to take a trip to NYC? are you for real... this is a 3 series for my wife and I have to change tires before a simple trip.
-Buy a can of Spare tire in a can before taking a trip or other tire repair areosol...no way
On paper the benefits of RTF are not worth it, you also conveniently didn't address the noise and performace problems stated on this Web page.
In any case I have made my mind not to pursue the 328ix so hopefully you will make the best decision for yourself assuming you are a real buyer.

There is a LOT of racket about RFT on the Internet. None of it good either. It's not a product I would personally enjoy defending at this point, given what I've seen. Of course, I do agree that there is both good and mis-information on the subject, but then, welcome to the Internet!
At best, it seems like this is a technology one has to "nurse" or "accomodate", which is, if you think about it, the very thing RFTs were supposed to avoid. THey are supposed to eliminate worry and hassle, not cause it.

"-BIG price differential of the RTF tires vs normal tire."
For a 328xi tires in the size of 205/55 R16 are recommended. In that size, conventional All-Season GFTs run between about $90 and $110, the Continental ContiProContact SSR RFTs cost $111. Hmmm, BIG price difference?
"-Change tires to take a trip to NYC? are you for real... this is a 3 series for my wife and I have to change tires before a simple trip."
I think you missed my point. What I was suggesting was chucking the RFTs alltogether and replacing them with GFTs for the duration of owning the car. Then when you sell it, or at lease end, put the RFTs back on.
"-Buy a can of Spare tire in a can before taking a trip or other tire repair areosol...no way"
Why not? That is standard issue on many high end cars these days (can you say Porsche?). The cans work well and are a hell of a lot easier to use than changing a tire. Your wife might actually appreciate this alternative.
"On paper the benefits of RTF are not worth it, you also conveniently didn't address the noise and performace problems stated on this Web page."
Sure I did. Virtually every complaint I've seen regarding the noise has been related to the early Bridgestone All-Season RFTs. I have yet to see any such complaints about the Continental RFTs and the jury is still out on the revised Bridgestones. Regarding the performance, by most accounts these tires perform pretty well, not quite as good as GFTs mind you, but not horrible bad either.
"...assuming you are a real buyer."
Nah, I'm just some twelve year old snot nose kid who doesn't have a clue about real cars.

Ok I know RFT = Run Flat Tire so does GFT = Go Flat Tire?
Seriously tho, what does it stand for?
I'd ditch the horrible RFT's and put on regular tires and buy 5 rims but what do you do for a spare and where the heck will you be able to keep it in a 1 or 3 series?
I know you can use a can but in general the cans can only fix certain things if you lose a sidewall you're walking.
Also what do you do if the tires in th front are a different size than the back?
I like the idea of the 135i but hate RFT's.

Can you back up this statement?
"8) Contrary to what you may have heard, RFTs can be repaired in the same manner as GFTs, assuming of course you don't drive too far on the tire with the low pressure.
BMW and Bridgestone clearly state the opposite position
..I had a nail in one of the replacement RFTs after 4500 miles., the orignals were from the defective batch, still had to pay $350 to the dealer as they had more that 10k miles.
When I found out I was going to have to buy yet another tire due to the nail, I hit the roof. However ,I was luckly as the dealer scored the hell out of the rim replacing the tire..got the dealer to pay for it and they have to repair the damage to the rim.
I want non-RFT tire and BMW should be forced to provide the spare,rim and jacks for all of us who got ripped off by their stupid experiment starting with the 06 models

Yes, GFT is Go Flat Tire. You might read back in this discussion to see how some members approach the no-spare issue when replacing the RFTs. Shipo addresses this just a couple of posts ago, and others have discussed it over time. The search feature would help you pinpoint the posts.
