I put them on the CEO's ML500 a few months ago. They are great tires, no complaints.

can you get them at Costco and how much were they.

I have been told they are now available at Costco. When I first got them, they were custom order and many tire shops didn't even know they existed.

Excellent writeup! We ought to take these truly outstanding reviews and put in separate area for reference. Information like this isn't available in the car magazines or automotive websites.

Maybe i should add it to the e70 comprehensive review post. Hmmm. How can i include it without hi-jacking my own thread???

Great review. I just put these tires on my wifes x5. We live in the Fort Campbell KY area and get a mix of everything. It sounds like these are going to be the perfect fit for our wx conditions.
Thanks again for your detailed review.

Excellent review X5Boston.
Hope you get some commissions from Tirerack with all the orders going through for the Latitudes' at this time! ;)

In your opinion, how do you think the Latitudes will fair on an occasional ski trip? I live in Arizona and drive to Colorado a couple times - i would love to take the X5, but the tires holding up are a big concern (it is not really worth investing in a set of 18" for the occasional trip).

I agree with everything that BostonX5 said. I put Michelin Lattitudes on my 4.4i Sport last Fall. A few weeks ago we had 4" of snow in Nashville (a lot for this area) and I went out driving to test them out. They performed very well on unplowed roads where the Diamaris would have made me very nervous. I also find them to be very good in the rain. Very surefooted at 80 mph in a heavy downpour this morning. The only drawback to these is that you lose a bit of handling and steering feel compared to the Diamaris. They feel a bit heavier on the car. That was expected, going from a summer performance tire to an all-season. However, I think that the Lattitude is a better match for the X5 which is supposed to be an SAV and not a sports car. Also according to the treadwear rating, they should last twice as long.

I wouldn't put too much faith in those tire ratings. I got about 32k miles out of my last set of Bridgestone Turanza, which had a rating of 140. My current set of Pirelli Scorpion Zero Asym, which has a rating of 420 doesn't look like it will get me past 25k miles.

These are excellent tires. Costco was out of them when I was looking to purchase them two months ago. But got it off TireRack for $207 each for the 255/55HR18s. The treadwear on my old Energy MXV4+ were 400 and lasted 50k miles. With the 440 treadwear I'm hoping they actually do last longer.
