RFT or Non-RFT? that is the question..
So I have read a lot on this forum about people getting non-rft tires and either just rolling like that and not worrying about flats or putting a full size or smaller spare tire in the trunk.
I dont want to put a spare tire in the trunk. So RFT is probably best for me, but I would like the more forgiving ride of a non-RFT. According to tire rack there are only 3 tires for me to choose from in a summer oriented RFT tire (I have a set of winter wheels).. RFT Bridgestone Potenza RE050A RFT - $1182 Pirelli P Zero Run Flat - $1196 (after Mail-in-rebate) Dunlop SP Sport 01 DSST RunOnFlat - $1254 (after Mail-in-rebate) Non-RFT BFGoodrich g-Force T/A KDW 2 - $664 this seems ungodly expensive for a set of 4 RFT tires, but what can i do.. anyone have experience with any of these? I want to get at least 25,000 miles out of my tires... I am in NOVA and drive in rain somewhat often (I read a review that Pirelli tire is only ok in the rain) and don't drive incredibly spirited when it is raining. The Bridgestone has poor reviews.. Can you convince me to get non-rft and not have a spare? That would be best for me but I don't have AAA (my BMW warranty runs out June 2013 - so the same for BMW Assist/Roadside Assistance - will the help if I get a flat?). I do take the car on long road-trips every now and then, so the thought of getting a flat and not having a spare or RFT sucks.

You can get the M mobility kit and get non runflats. The M mobility kit includes an electric air pump and puncture seal material. I had an E46 M3 and that is BMWs "spare tire" solution.
I had my M3 for 9 years and never used the kit. |

Take the $600 you're saving, buy the mobility kit mentioned above and buy a $100 AAA membership? If it's a nail, the kit should get you to a tire shop... If it's a blow out, AAA will come and get you.
AAA and BMW Assist use the same towing companies... difference being that BMW will only compensate the tow company if your car ends up at a dealership.

The Best for me... NON run flat, BUT always EXTRA-LOAD (XL)
Actually I have installed in a e81 pack M: Michelin Pilot Sport 3 Extra-Load. PD extra-load la carcasa o estructura del neumático es mas resistente. Reducirás la sensación blanda de montar neumáticos convencionales sin extra-load La suspensión del pack M es bastante enérgica. Sino notarias el neumático blando. |

When my wife ripped the sidewalls of two tires (and ruined two wheels) on a granite curb in my then new E46, I had the car towed (flat bedded) to my house so I could put on another set of wheels. |

I will try to explicate you in english.
Tire has 3 parts. Banda de rodadura. The part what take with tarmac. Flanco.outside and inside side, where is write the numbers. Carcasa o estructura interna. What you can't see. That normally is composed for several layers. Extra-Load is another layer. A reforced layer. This is used en sport cars, as Ferrari, Porsche... you can drive more agressive with more security. What is the diferent between Extra-Load and Run-Flat? Extra-Load is a reforced internal layer. Is something general inside de tire. Run-Flat is a reforced side. It is only reforced de flanks. Layer tire: Last edited by SSunklug; 08-30-2012 at 04:33 PM.. |

Why is necesary a Extra-Load tire?
Simple, Run-Flat is a more rigid-stiff flanks. Pack M suspension y more agressive o rigd-stiff. If you install a conventional tire, an agressive suspension, as pack M or a sport car, will do that the tire finally """squash""" into the tarmac. It is probably that you feel the tire more "weak" or "soft". That in Spain is called: "Flaneo" It's probablye you can understand it with this video. But "Flaneo" happens when you are driving. |

But you don't have to confused with the type of compound (soft, hard, medium, supersoft...).
That you can see it in code: 00W 89Y 91Z .... The letter, more soft o more hard composed: The number, more or less weight. |

FYI (from the ComfortKit instructions):
Use of sealant on damaged tyres linked with a tyre pressure monitoring system may lead to error prompts and incorrect readings by the air-pressure sensor. When replacing such tyres, make sure you observe the vehicle manufacturer’s instructions with regard to the sensor. In case of doubt, you are recommended to replace the sensor.
