I have 4500 miles on my 2008 335xi coupe, with the Conti RFT tires...i keep 28psi in front & 30 in rear for a smoother ride...so far, so good, albeit as we all know, you feel the bumps, but at 75mph on a free-way, its smoother than my 2005 545...
i have noticed a bit of air leakage, perhaps 1-2 pounds over a couple of week period...the BMW shop forman says its not unusual, just fill them up and check once a week...
i think its nonsense about replacing one tire & damage to the x-drive is "nuts"!!!

Thanks for the feedback.
I am glad you have the same feeling about the xDrive. I was thinking it is impossible to be affected by a 1/8th or 1/4th inch difference.
I'll continue to refill that tire for now.

I don't think it is normal for a tire to lose 1 or 2 pounds of air pressure every couple weeks. If indeed it is the case, you need to get the tire checked out, probably not by the BMW dealer service you went to. Make sure you check the tire pressures in the morning before the car was driven to get the correct reading.
As to the replacement of one tire leading to possible damage to the axle, it is true if you already have 10,000 miles on both tires. Check with Mike Miller of Tech Talk at Roundel. He will tell you so.
As an owner of a BMW, you may want to join the CCA. The BMW membership magazine, Roundel, is well worth many times of the membership fee, not to mention the rebate you'll receive when you consider the purchase/lease of another new BMW in the future.

I also have the Conti RFT's on my 2007 328xi. I have yet to replace them and have about 19K (orig tires, car purchased 1/1/07). I've definetly hit some hard potholes, but overall, mostly highway miles. Personally, although the taxes are outrageous, central NY takes great care of the roads, so I think thats part of the reason the tire wear/ride has been decent. My only complaint is that there is noise on some road surfaces, but after reading some of these posts, I feel pretty lucky/happy w/ the tires I have.
BTW, tires are: Conti Pro Contact SSR - 225/45R 17 - o I also wanted to add - I have never checked tire pressure or rotated the tires.

I just bought new Conti's for this 330xi I lease. I rotated the last set front to back, same side every 5-6K miles and never had noise. Wear was extremely even with this approach. Great tire, IMHO.
#1931 of 3108 Spare Tire and Rim
Jul 04, 2008 (1:49 pm)
Occasionally folks have mentioned they purchased a spare donut tire with a rim and a jack. If I chose to do this where would be the best place to do so?

i bought a full size spare and an extra wheel. I know it takes up a hell of lot of space but with the drop down rear seat in the 335xi it's tolerable. I had a jack left over from my last bmw and it fits nicely in the (inadequate) well. I got the wheel from my bmw dealer ($286) and the tire from tire rack $145. had it put together at my local tire guy ($30). I bungy cord it in the trunk and so far everything fits nicely (luggage for a 2000 mile trip for 2 as well).
#1933 of 3108 BMW 2006 330i RFT problem Mileage 18K
Jul 05, 2008 (9:10 am)
I have major problem with my tires, this is the second set of tires I purchased, a total 8 tires $2500. just brought another one today, 328.00 from Tire Rack. I keep getting side wall damage , Bridgestone Potenza runflat tires are horrible. I also declined the tire insurance, which I now regret, I drive safely avoid potholes and it doesn't matter, still get side wall (bubble) damage, does anyone know if I can replace these RFT with
regular tires, the car does not have a spare. There is a sensor that tell you when the tire pressure is low, will this work if I remove the RFT, any help is appreciated..
#1934 of 3108 bridgestone run flats
Jul 05, 2008 (11:29 am)
bridgestone/firestone same company. dump the run flats and buy a good set of regular tires. save one for a spare in case of flat and be happy.
caio for now

the 335i is my second car with RFT. My first is my 99 vette which I still have.
First--only lose air as the temp changes and by that I mean when we go from summer to winter type temp changes.
Second--each mfg RFT handles differently, rides differently etc. ie--I found the Firestones to be better than OE Goodyears on ride, handling and quiet.
Finally--I have driven cross country several times--got a sidewall bubble from a pothole on the interstate in New Mexico, it happens.
and I got a flat late nite in Joplin Mo--what happened as I finished an all day run i added air as I was headed north te next day and expected cooler temps-in doing so--on on etire the air hose locked to the vale and broke the valve--the FRT allowed my to drive the 5 miles to the hotel and a local goodyear dealer put in a regular valve so I could continue the trip. That was probably 7-8 years ago so now more dealers have the equipment and knowledge to work with RFT's. But all you need is to be caught 1 time without a spare or not have the right air and sealent and you are in a heap of trouble!
