Switching RFTs to Normal - Any issues?
I'm planning on replacing the OEM RFTs to normal PS2s or PZeros when they wear out, show bubbles on the side, or one becomes unrepairable for another reason. I have read that people have had issues like electronic warnings and gremlins in the low pressure warning system when switching to normal tires.
Questions: Has anyone done the switch on a new F10? If so, have you had any computer problems attributed to the switch? Apparently BMW claims that the switch to normal tires may have an adverse effect on handling because the car was developed to run on RFTs. Any truth to that? |

I went to conventional tires from RFT on my E92 (same TPMS as F10) with no issues except for improvements noted above. I plan to do the same on my F10.

Why are you willing to exchange your RFT's with normal tires?? Is it because the sound issues and drivability??
If that's the case, then I've seen a couple of reviews on YouTube for the F10/11 that the tires on these cars are very silent even though its new tires they were testing. They also said they handle well. Ofcourse, you can't know for sure until you really try them yourself for several kmiles |

This topic confuses me unless RFT switchers are buying a spare wheel (and tyre) and jack along with finding a secure place to carry same...or are switchers taking a chance with being stranded with a flat..?

Not cheap but BMW does sell a "mobility kit" which contains exactly what uktivo describes. Came standard on my M3 which does not have runflats or a spare...

I see that Kev is in Ireland. Out in in the far reaches here in the colonies, you can literally drive hundreds of miles between towns. Or where I live, in the Southeast, everything shuts down for the Lord's day (Sunday) and you generally can't get a tire fixed, anywhere. So trip planning may be a little different than in the UK or Europe. RFTs are not the panacea that you might wish for (not to end a sentence in a preposition). You should have a bottle of slime and air compressor in your trunk regardless of the tire type. Or a can of fix-a-flat if you prefer. Me, I carry the former and on out of town trips, I have a spare, jack and lug wrench. You can get a kit from Tischer BMW that has everything you need, around $350. Expensive? Yes. How much for two nights in a hotel, ruined vacation and delayed trip? Priceless. And the F10 trunk is so huge you can put a mini spare back there and still have room for luggage. I used to put the spare in my E92, and that was a tiny trunk, but we still made it work. References: Spare tire kit Slime

Even if one did not carry a spare one would just call the tow truck and go to the tire repair shop to take care of it - no "insurance liability issues" to repair a regular tire - or one can even have the tow truck driver repair the tire with a plug and continue the journey immediately thereafter. If the tire is ruined - which is unlikely - the chances of finding a replacement in the size one needs are much greater. BTW, I'm planning on buying a spare and what is needed to install it.

RFT Replacement
I have been driving a 2004 545i for the past 6 years. The OEM RFT tires that came with the car were so noisy that the dealer replaced them with non RFT Michelins on a "good will" basis. I have subsequently changed them with another set of non RFT tires as you have a much larger selection and they are generally less expensive. Both sets of non RFT replacement tires have served me well and I have not had any problems with the tire pressure monitor or noticed any significant change in the handling of the car. I plan to purchase a F10 at some point and my replacement tires will be non RFT.

The kit that I referenced above is not a "space saver" but it is a smaller wheel and tire than OE. Since it is for the E60 it should fit the F10, but one of these days (maybe this weekend?) I'll verify that it actually does fit and clear the brakes.

I switched over to Michelin Sport Pilot A/S and haven't had any problems. Better ride quality + handing in my opinion.
Also I think it's weird that the sport package comes standard with Grand Touring tires and not ultra performance ones. |

Its not weird it reflects that BMW's Priority with this car was the added comfort the Grand Touring tires would provide and were willing to sacrifice performance even in the Msport version to get it.

Does that Slime kit work with the RFT of the F10? Is it that simple to use and is it that effective? How long can you drive with this fix? My wife would be the main driver for the F10 550i and I may buy her this kit since it looks easy to do. My wife is a petite woman so she won't be able to do any tire fixing if there is a flat.

2011 550i received. This is my first BMW and I am glad I chose the F10 to be the starting point.

The TPMS sensor may become inoperative but once cleaned (with water) of the SLiME product it will be fine, or so they claim. Fortunately, I've never had to use it, but I have a kit in the car and one on the motorcycle. Can't patch bike tires. Well, you "can" but you shouldn't. -mjb

As for the sport package cars - I don't see why this won't work for you as well, as long as the wheel fits (and with a spacer it should, as your brakes are the same as mine) with a spacer as noted above. Sure, the car will list to the side and you'll likely need to turn off the DSC, DTC, etc. because of the different rotation speeds, but you'll get home OK. And that's what really matters.

It's soo much easier when you do not have a choice.... Same as on M5.... Wonder why those perfomance beasts are not on RTFs..... Well I tried 200 km\h and above and those RTFs where really not providing a smooth ride, was becoming a bit rough....
