Swapping out Run Flats?

[X5_Rob]

My front OEM's are needing replacing.. The rears must have already been replaced as they look pretty good.. Car has 21k miles... Both are the OEM Bridgestone Dueller Run FLats... I want to get off the run flats and into standard tires...

My plan is to replace the fronts with standars first and then the rears when they go... I believe the rears have 50% tread on them and good for another 10k-15k miles..

Any issues with running front standard tires with OEM run flats in the rear?

I did this to my C5 no issues.. I couldn't stand those run flats - crazy loud and bumpy....

well.... I guess this will take some getting used to... the lack of "action" on the X6 forums... just not enough of these cars on the road or owners on these forums i guess... I have an X5 e53 and that forum has a lot of posts and replies to every topic imaginable..

After doing some googling regarding different tires decided to get off of the run flats and onto standard tires again.. pulled the trigger on the Nitto Motivo's 275/315's...

I did this to my Corvette convertible which was way too loud with the OEM run flats and made a world of difference to the interior volume.. quite frankly never noticed a difference at all in the driveability.. Hopefully the same holds true for the Motivo's on my X..

If the tread pattern is same on all 4 and you are not driving on track or high speed on ramps you should be ok.
I guess you bought all 4 already.

I went ahead and just replaced all 4.. my goal was to get the cars loud road sound tamed down might as well get all 4 RFs off.. I'm having them mounted on Tuesday..

Only just spotted this, but in the UK a lot of both E70 & E71 owners are ditching RFT for normal tyres on the 20" wheels because of the improved ride comfort. The only requirement owners are advised to meet is to tell our insurer because as the cars aren't offered in our market without RFT, changing counts as a 'mod' and needs to be notified so as to avoid the insurers walking away in the event of an incident.

BMW GB also refuse to warranty the transmission if there are issues, as the tyres are now non-standard.

I can't see any engineering reasons why you would not be fine with a pair of each, as long as you have something to cover you in the event of a flat.

Yes I dumped the rft's. Now the ride is MUCH smoother! I also put 19" instead of 20" and there is almost no difference in the look but now, NO Kerb damage and the car is much softer. When I press sport button the ride is hard and the car still steers pretty good. Just drove to Germany on autobahn doing 260 kmh

I ran over something on the interstate at 70mph in an empty construction zone (concrete barriers on each side of single lane). I was able to drive the rest of the way to my destination before finding a remedy. Had I been running on non-RFT, I could have blown out, hit the concrete and/or made lots of friends by bringing interstate travel to a halt (because there was no shoulder). Run-flats are expensive, stupid expensive, compared to non-RFT. And yes, they produce more noise and are not as soft. But...at the end of the day, for the experience I had, and the peace of mind knowing I'll most likely NOT swerve, over-correct, flip or crash if I run over something again, I'll gladly pay the price (of cost & noise). I'd also feel a little silly sitting on the side of the road with a flat non-RFT and no spare.
