#3132 of 3282 Re: X3 2004 Creaking Noise & Mix Tires problems [mohannad] by roadburner Aug 12, 2008 (10:42 am)
Replying to: mohannad (Aug 12, 2008 3:20 am) the first problem is the creaking noise which comes from all the doors (or windows) when ever i drive over a non smooth road   BMW of North America has released a couple of service bulletins on the topic. If your local dealer cannot obtain the bulletin you might try lubricating the door seals and window channels with a rubber compatible product such as Vinylex.   the second problem which caused the dealer to get me a new gear box thinking the problem resides there but it wasn't from the gearbox.   The problem is that BMW's all wheel drive system is designed to work with four identical tires. Mixing tires of different diameters can cause the problem you describe. Run the same size tire on all four wheels.   last problem, my windows used to go down and up by pressing the key once, after i took it for maintenance check, i lost this feature, and the dealer guys are saying i don't have that feature ....so any clue how can i get this feature back.   The one touch feature can be enabled or disabled by the dealer. It sounds like your dealer does not know very much-if anything-about the X3. Is there another dealer in KSA that you could bring the car to?
#3133 of 3282 Catalytic converter & Octane questions by jrynn Aug 13, 2008 (11:23 am)
LEADED gas will wreck your catalytic converter, not typical grades of unleaded gas.   BMW (and other premium manufacturers) use premium fuel so that when they test (and report) engine performance, they can max out horsepower and torque numbers. That they recommend 91 octane is rather silly, as the typical grades sold at US gas stations are 87/89/93.
#3134 of 3282 Octane by califjohn1 Aug 25, 2008 (6:46 am)
In California (and I think most of the West Coast) the highest octane you get is 91.
#3135 of 3282 Octane by jrynn Aug 25, 2008 (11:08 am)
Then you might want to edit the Wikipedia entry on octane which says:   "Octane ratings can vary greatly from region to region. For example, the minimum octane rating available in much of the United States is 87 AKI and the highest is 93."   Exceptions for California (state-wide) and some high-altitude gas stations in other states are noted in the entry. The discussion re California also notes that it's possible to buy 100 octane at some stations and that earlier this decade 92 octane was sold.
#3136 of 3282 Octane by califjohn1 Sep 02, 2008 (7:05 am)
Can't speak to the Wikipedia entry, which may or may not be correct. All I can do is relate from personal experience that never have I seen 100 octane in CA outside of an FBO at airports. There probably are places you can get 100 octane but I seriously doubt they are your local gas station. Have never seen 92 either, but I suppose it might have been sold somewhere in the state. What you WILL see are 87,89, and 91 octane at CA pumps. Replies to this message: szimdahl (Sep 03, 2008 5:43 am)

Replying to: califjohn1 (Sep 02, 2008 7:05 am) In Chicago we see a variety of different grades of gas depending on what station you are at. BP, Shell, and Mobil all have 93 Octane Premium, while some stations like Speedway and Thornton's have 92 Octane Premium. Most other stations only have 91 Octane Premium. I also drove to St. Louis this past weekend and stopped at a Thornton's gas station that had 87, 90, and 92.
#3138 of 3282 Tires for X3 w/sport pkg and 19-inch wheels by bmwguys Sep 07, 2008 (4:43 am)
We're south of Chicago, and just bought an X3 with the sport package and 19-inch wheel upgrade (pick it up next week). The 19-inch wheels come with 3-season performance tires rather than all-season tires.   Our dealer recommended buying a set of tires/rims for winter. Anyone know of appropriate all-season tires that will fit the BMW 19-inch rims? If possible, we'd love to avoid swapping tires/wheels every winter and spring.   Sizes are: 235/45R-19 front and 255/40R-19 rear   Thoughts?

Replying to: bmwguys (Sep 07, 2008 4:43 am) If you buy the stock size 17" tires for the X3 (235/55-17?.. something like that), you will probably save enough money over the 19" tires to buy a set of wheels to go along with them.. Plus, I bet 19" winter tires are hard to come by, especially in staggered sizes.. It will be much easier to swap a set of tires/wheels, than to change tires on the current wheels.. Either way, you have to tote 4 tires to the dealer, but with dedicated tire/wheel combinations you don't have to mount/remount each time (and at additional cost).   Also.. I wouldn't exactly call your current 19" tires, "three season".. Well, I guess that depends where you live... but, once it gets below 40F, those summer performance tires will get hard and slick, even if the weather is dry..   I'd look for a used set of factory 17" wheels. Check eBay. Should be $500-$600, at most. Then buy 17" winter tires to go on them.   I've noticed a lot of BMW corporate owned X3s hitting the dealer lots with the 19" wheel/summer tire upgrade.. Those are great, if you are on a 1-year lease... Not so great, once you have to replace those monster tires..   Good luck kyfdx visiting host Replies to this message: bodble2 (Sep 09, 2008 5:53 pm) cdnpinhead (Sep 09, 2008 6:00 pm)

If possible, we'd love to avoid swapping tires/wheels every winter and spring.   I second your dealer and kyfdx. It takes me 45 minutes to swap all four corners over to my winter wheels and tires. And 19" tires-even "all seasons" will not handle the nasty stuff as well as 17" winter tires will.

Replying to: kyfdx (Sep 07, 2008 2:09 pm) "...you have to tote 4 tires to the dealer,..."   The BMW dealers around here will store a set of tires for you at their dealership full-time.... for an annual rent of around $300. No chump change, but to save the hassle of storing 4 tires in a crowded garage (and risk getting them stolen), and lug 4 dirty tires across town twice a year....
