Hello everybody
I recently got a 2007 550i with sport package. I have a 24 mos lease. Does anybody know how long those tires last before they need to be replaced? I heard 10k miles...is it true?
I'd really appreciate your feedback.
Thanks

How long a tire lasts is based on many factors, not the least of which is driving style. You'd have to be a darn aggressive driver for tires to last only 10,000 miles. As a data point, I replaced my run flats at 17,000 miles because I got a screw in one of the rears, and I couldn't get it repaired because it was down to the wear bars at the very center. If it weren't for the puncture, my guess is I would have gotten at least 20,000 miles on the rears, and more on the fronts (which were pretty far from the wear bars).

I see you live in south Florida, and having lived there years ago, I remember how hard the heat and roads were on tires, so you'd probably reduce my mileage by some factor.

data point:

I have 14xxx mi and at least 10K more to go extrapolating wear.

I'm over 12K with my 2007 550i also with the sport package... Not anticipating needing to replace them anytime soon--they look good! (Not counting the one that had to be replaced due to a freaking pothole! I've lived in California all of my life--I've never seen our infrastructure as bad as it is these days....)

The first 800-or-so miles were Autobahn miles!

A few guys on the E90 Forum have gotten 30,000 on their runflats. That makes them quite economical even considering their high initial cost.

Have 10,400 and based on thread wear, I should be able to get another 10K.

Just changed rear driver side tire today at a cost of $ 372 (installed). Was loosing about 4 lbs air per week and found our that I had a two inch nail. Should be able to get $ 350 from my tire insurance.

Thanks everyone for your feedback. So I guess I'm gonna have to change tires before my lease ends.

I'm not so sure about that my friend. Here's a couple of photos of my RFT's after 7K miles - they look like brand new!!! :thumbup:

I drive a 330i, and I just ordered new set of tires after 27000 miles.
I elected to to go with the regular tires as replacment

At the end of the lease the tires have to have a minimum of 4/32" tread left (new tires are about 10/32"), or they will charge for tires.

All 3 of my BMW's have had similar wear on the rear tires....at the edges. The BMW Service Advisor told me that was normal due to the suspension/handling setup on the cars. Since I had it on all 3 cars, I think he was right. I have always been careful to monitor inflation pressures weekly for optimum handling and tire life.

I now have 10,3xx miles on mine and they look about the same as in my original post. I'd say I'm on track for about 25K miles before my order arrives from tirerack.com!!!

Same here. 2 years/30K miles lease. I have close to 16K miles on my RFT Dunlops and rears are half gone. I refuse to use winter tires so my only choice seems to be wait till they are close to 3/32 in depth and replace RFTs with cheaper non-RFTS. A set of Pirellys can be had for about $600. I will have to put RFTs back before returning the car though.

This may seem like nitpicking, but a runflat tire won't wear faster or slower than an equivalent conventional tire. The only difference compared to a conventional tire is the heavily reinforced sidewall.

Tread compound will determine tire life to a great extent. Higher performance tires have "stickier" tread compounds. In my experience, I've seen the following:

A high performance summer tire on a ZSP car will probably get about 15 to 25k miles, depending on driving style, tire model, etc.

A "medium" performance all season like the Pirelli Scorpions on my X3 will probably last 25-35,000 miles.

A "low" performance tire on an inexpensive family sedan will get closer to 50,000 miles.

Tirerack offers good reviews that include both tests owner's opinions of tread life.

I'm on my second set of Dunlop RFT's....First set was replaced at 11k by the dealer at no cost (they were extraordinarily loud but still had some tread left). I'm up to 16k on the second set and the loud road noise from the tires is back. I've still got a bit of tread left but absolutely cannot stand the noise. Will probably replace them soon, but possibly with another brand.

Pete,
Dealer changed out 3 sets of tires for free because of the horrendous noise they were making with plenty of tread left. First set at 10k, then at 21k, then at 38k. Take it down to the dealer and complain about the noise. There was a bulletin out on the Dunlaps. I finally bought my own set at 60k, but put on Michellin non-run flats- Couldn't stand that noise
