M Sport OEM Run-Flat Tires - what did your X1 come with?
There seem to be just two OEM tires that are delivered on M Sports in the US. I've read that the Pirelli Cinturato P7 Run Flat are a bit more inspiring than the low rolling resistance Goodyear Efficient Grip RunOnFlat. Now that A/S tires are an option, any reports on what tire is being provided?
Please comment on your impressions of the OEM tires. http://www.tirerack.com/tires/tests/...y.jsp?ttid=158 |
The Goodyears haven't impressed me at all, but then I didn't expect much since I don't like runflats. I almost didn't buy the car because of the tires. Come springtime, I might not even mount them when the winters come off. I'll probably store them to put back on at trade-in, and go with a conventional/non-rft performance tire.

Any M Sport owners wish to chime in?

19" Pirelli Cinturato P7 Run Flat

18" Pirelli Cinturato P7

18" good years... I think they're fine

After reading the F30 forums, consensus seems to rate the RFTs in this order:
1. Bridgestone Potenza S001 RFT 2. Pirelli Cinturato P7 Run Flat 3. Goodyear Efficient Grip RunOnFlat I wouldn't be surprised if BMW has seen the err of their ways (like with the paddle shift fiasco) and have stopped putting Goodyear's on M Sports, making the Pirellis the default M Sport summer tire. Perhaps we'll even see the Bridgestones soon since they are offered on F30 M Sports. Hopefully, Tire Rack performs another road test that includes the newer Bridgestone and Goodyear. I have a feeling that Michelin is still king of the hill. |
Z4Dennis, did you get A/S tires with your M-Sport. What tires were they? Are the wheels still staggered?

Hi Guys, new to the forum. My 2011 X1 M Sport came with 18 inch Pirelli's but 225/45 for front and 255/40 for rear (from memory, but definitely different profile). They grip fine for summer tyres in summer conditions but aree noisy. Mine is a UK 2.0 130 kw disel engine and the engine noise could not drown out the road noise on motorways (your US freeways).
Now I am hunting high and low for run-on-flats winter tyres with 68db or less noise on 225/50 17 inch to experiment. Found only one in UK websites Dumlop Winter SP3 run on flats but dealers seem only to stock this one non-run-flat. Boo. Any UK forum members have ideas ? |
Mine came with Goodyears and couldn't be more displeased. They'll be off within a month in favor of Michelin Pilot Sport A/S on some kind of 5-spoke rims. Maybe these...

I have my 2013 M Sport now, ordered at the end of November.
I ended up with the All-Season tires option (which supposedly wasn't a choice yet): 18" Pirelli Cinturato P7 All-Season Run Flat (different tire than the Summer Pirelli Cinturato P7 Run Flat). The wheels are non-staggered, so 225/45 all around (just like on the F30 M-Sport all-seasons). This likely means I don't have the increased top speed limiter (not a big deal as I should never be driving this baby hauler that fast). Ride is very comfortable (especially for run-flats), but grip is a lacking a bit compared to the performance summer tires I'm used to. The square setup should reduce understeer vs the staggered. I plan to remove the run-flats once they wear. I'd like get a bit more rubber and fit 235/45s. Plan is to fit Michelin Pilot Super Sports (best tire I have ever owned...transformed my E90 335i) and keep a donut in the boot. http://www.bimmerfest.com/forums/sho...d.php?t=667528 http://www.bavauto.com/assets/imglib500/spare.jpg |
....not sure if I will rotate the tires or not. I just want to get to the Pilot Super Sports ASAP. :cool:

I was so unsatisfied with the P7 All-Seasons that I headed back to the dealer Monday. They corrected the problem and replaced the wheels and tires with the proper staggered wheels and Summer P7s. Oh, what a difference...night and day!
The confidence in cornering I had when test driving has returned. I've also noticed an improvement in braking (as suspected). Understeer has not been a problem. I don't plan to test the handling limits any more extremely than I have so far, so understeer is no longer a concern of mine. I am happy enough with the Summer P7s that I will not get rid of the runflats. I also don't want to give up cargo space for the donut. In my opinion, it is better to run Summer tires and get a separate set of winter tires if your climate dictates it. The all-seasons are a compromise in every sense of the word. |

A Goodyear for P7 swap might have worked before you drove your car off of the lot only if they had an M Sport sitting on the lot with P7s. I believe BMW has abandoned the Goodyears and the Pirellis are standard now. |

In these cold temps, the X1 reported low pressure indicators on all four tires.
Since I wanted to inflate them as close to max pressure for better crisper handling and mileage, I finally got down to read the details: Pirelli P-Zero 225/40 R19 89W Max Pressure 51 (I set mine to 45psi front and 48psi rear) Treadwear 225, Traction AA, Temp A This is an M Sport X1 picked up on ED. These perform great on dry pavement, but horribly in my first snow the other day. I skidded 70-feet past my driveway!! I felt like I had skis on versus tires. I need some good snows for this car - any recommendations? |
I think while your ease of steering increases, your grip will decrease with high air pressure. I've never set any tires that high. Lower PSI will give your more grip. Take a look at the recommended pressures on your door panel and adjust from there.
I've never driven in snow but I am a believer that Michelin makes the best tires these days. |

Our X1 35i had the staggered wheels with the 18" Goodyear Efficient Grip RunOnFlat tires. They are 'summer grand touring tires' so I didnt expect much from them in the snow. But we got whacked with a snow storm and a lot of ice a few days ago and it handled it it pretty well. Better than I thought it would, I really didnt want summer tires or the staggered wheels, didnt say anything about summer tires or the 'free' optional wheels on the window sticker so I just assumed there were all season.
They are a bit noisy on rough pavement, overall the ride is OK though and I'm not going to run out and replace them for a while. I havent found any all season run flats in the 225/255 18" size tire so the Goodyear run flats are staying for a while I guess, unless I run across a set of standard wheel/tires. |

Cinturato Run Flats... Getting my car today!!!!!!!!!!!!!!!!!!

Wife's new 2013 X1 3.5 M-sport came with the Pirelli 18s but how can i tell whether they are summer performance or A/S. (Eyesight is not so good, so need to know what to look for.) Drove it in the freezing rain this morning and they were rock solid, but I was not doing any too crazy.
