I know the original post is from years ago, but I noticed something interesting when researching tires on tirerack. The pilot MXM4 that many X3's come with don't rate very highly as a total roll up. However, if you drill down my car manufacturer to BMW, most of the reviews are in the 8-9 range.

I was planning on switching tires when mine wore out, but I just recently had 2 punctures and since I have the tire coverage from the dealer, I got 2 brand new MXM4's as replacements at no cost. Guess there goes a new tire model for me.

I hope you went ahead and replaced all four at the same time. New tires mixed with very worn tires on an X3 can cause problems with the XDrive due to the difference in circumference.

Isn't that only the case if both fronts or both rears don't match each other? Even the optional staggered 19" option from BMW has different diameters between the front and rear.

No, the optional 19" staggered tires have the same OD front and back. More than 0.2" OD variation will wreak havoc with any full time AWD system (not a BMW unique issue). You have to replace all 4 tires as a set.

Staggered tires on a AWD vehicle is just plain silly.

Just another credit to the Michelin A/S. Today the east coast is obviously being hammered by Hurrican Irene.

As an engineer for Sirius/XM I am considered "Essential Personnel" and must be at work under any conditions.

While driving down 95 this evening under pouring rain I didn't lose traction once. Hit lots of deep trenches of rain and had to avoid a couple of dopy drivers doing 40 in the passing lane.

The tires were checked to 34 PSI all around the day before today.

Nice testament to both the tires and the vehicle. Under both heavy snow (3 feet in two days) and heavy rain (6-9 inches) the Michelin A/S performed very well. At no time did I feel the vehicle was out of control due to weather.

just a thought.

I REALLY like the Pirellis but cant bring myself to spend that much on them, I have to replace my tires probably in the next 10k miles, but will probably be going with Falken Ziex-912 or Dunlop SP sport 9000 or maybe even ExtremeContact DWS all those tires are about 70-90 cheaper per tire than the STR's

I bought the Pirelli Scorpions last year for my X3. They are the BMW-recommended tires (star on the sidewall). They are available at Tire Rack and at Discount Tire for less than the price at the BMW dealer. My tires are stamped "Made in Germany", even though they are Pirellis.

They are definitely not a bargain, but the quality is excellent. Although, I suppose anything is cheap compared to the run-flat tires on my E90.

yeah those are the same ones I had, I had to replace one 2 months ago when I chunked a sidewall and had sticker shock! I paid more for that Scorpion that I did for the 33x13x18 inch AT tire I put on my Titan that I got rid of! I think I got my Scorpion for 225 installed.

I replaced my oem pirelli's with yoko avid envigor last year. They handle great and are extremely quite. Priced at less than $120 tire. The only draw back is the handling in the snow

The Michelin A/S sport were $167 each with a $70 rebate when I bought last year. The rebate basically covered the tire removal, disposal, and spin balancing.

IMO they are just that little n'th degree better than the Scorpions (which I had) in handling, ride comfort, all weather types (including treking through a logging road 6 inches deep in mud) and also about $10 cheaper.

I am not familiar with the other brands mentioned and the Scorpions are a great tire but all the little pluses with the Michelin added up.

BTW the 4 Michelins I replaced were essentially the cost of my Wife's 2 conti A/S run flats.

One of many reasons I think RFT are pushed as a cost savings to the MFG and not really that benefical to the consumer.

I'm reading the thread and noticed the push for the Primacy MXV4's. My current stock rims are 18" and all I see listed are the 235/60R18's for the Michelin Primacy's. Looks that I also have direct TPMS as I see metal valve stems. I'm at 42K with the original stock tires and need to replace them. So can I install the Michelin 235/60R's on my wheels or should I be looking at an exact replacement (235/50 R18) and what would you guys recommend. Looking more for longer tread life than performance (60K).

Hey everyone. I'd also like to know if it's recommended to stay with the original tires or it's safe to replace them with a different type. My mechanic stated that the X-Drive can get messed up because the OEM tires were made specifically for the car, but I have a hard time believing him. Also, is it common for the rear tires to wear much faster than the front tires? Thanks.

I swear the dealers are pushing this hard. I believe they are concerned about driveability issues with the transfer case.

If you use the same tires all around, it is easy. Pick a tire with good reviews on here and move forward.

If you have staggered, I would recommend a bit of research on alternative tires to be sure the front and rears are very similar to the stock tire diameter differential. e.g. the stock Dunlop SP 01 tires are listed as:

235 fronts: 27.3 in diameter, 761 revs/mile
255 rears: 27 in diameter, 765 revs/mile

Less than 1% difference (0.52%) Apparently the transfer case has a major problem when the tire rotations are not as similar.

My dealer put on Michelin Pilot Sports on my 2006 X3 and I have had many issues with driveability. The rotations/mile differ by 0.91% vs. the Dunlops 0.52%. However, these were recommended by BMW and the dealer installed them.

I have a 2007, non-sport and I just replaced the stock Primacy HX's with a set of Primacy MXV4s. Super quite and comfortable and a great all around tire. The sidewalls seem a little softer than I'd like, but I bought them because I wanted an all season tire with excellent wet grip, low noise and high treadwear (60k tire). Plus, I got the $70 rebate deal and they are Made in USA. I'm happy with them.

Thanks for the quick reply. One other quick question. I noticed the sticker on my door says the rear tires should be inflated with more pressure than the front. I'd like to know what you guys recommend running on your tires, OEM or not. Equal pressure or follow the BMW guidelines?

I follow recommended pressures. My dealer always puts them at 40 though.

I have Michelin Primacy AS. Great tires, stick well, very quiet, 60k warranty!

Rotate unless you have staggered sizes.

My sticker has the same pressure all around...but I have 235/255 staggered.

It's in the Owner's Manual too - much easier to look at than on the door sticker.

Especially as there are quite a few combos you have to decipher.

The 18" staggered setup is the only one that has equal (32) psi for a max. load of 4 people.
For a 5 person load, or 4 with luggage it's 35 and 38.

All the other tire options, including 19" staggered, have a 3 psi difference front to back for 4 in the vehicle, and a 6 psi difference if you have 5 people or 4 + luggage.

Given that there is quite a difference in psi for a load of 4 people versus 5,
you might wonder if with no passengers at all, you should run less psi than quoted for the max. load of 4 people.

I guess the short answer is, no. Same psi whether it's just you, or when you have 3 heavy friends aboard.

No, I have the standard 17" wheels and that's 32 psi for all 4 tires (unless I'm going > 100 mph with 4 people + luggage, which hasn't happened yet).

Yes, I forgot that recommended tire pressures almost certainly got revised for the 2007-on models.

Sure -- but that staggered fitment in 18 or 19 inches includes wide, lower profile tires in the back that have the same diameter/rolling circumference as the front tires.

Ever since my usual gas stations stopped having free air, I bought my own compressor for something like $45. Now my pressure is always right. I can check the tires when they are cold, unlike before when some short distance driving was done. Even a bean counter would agree that the compressor will pay for itself in possibly 6-7 years. If you have a 3 car family, it will pay for itself sooner.
I did the same thing. Even if it would not pay for itself, I would still do it. So good to check when they are actually COLD!

People keep mentioning Pirelli Scorpion, but my X3 came with Pirelli P Zero Nero. Is that because it came with the cold-weather option or that's what some previous owner put on?
