Time for new tire and I need advice on what others have used in the past.
 

I need to change my four tires but I don't know what to change them to.
Currently they're the OEM Michelin Energy tires size 255/55R18.

Any advice on what tires are good or bad? TireRack.com has the oem for about $800 and no name tires for about $450.

Appreciate any help you can give.

I was pretty happy with my Michelin MXV4 (Energy). Have they worked well for you? If so, get the same again. They are well suited to the X5.

If I had needed to replace mine, I would have gone with the same. I have had the same tires on other BMW vehicles, and have been happy with them there as well.

check craigslist for used oem tires. they are generally in good shape and cheap!

I was bored, so I perused TR site, looking at tires in your size; interestingly, the oe Micheys get so-so reviews, though I thought they were pretty good on my orig 18" wheels.

From a glance, disregarding the non-rated/lower "rated" tires, I suppose I would look at, in no particular order:
Kuhmo Road Venture, Kuhmo Solus, GY Fortera, General Grabber, Michey Latitude,(but pricey), Yoko Geolander, Yoko Avid Envigor, and a couple others.

Picks simply from scanning the review "ratings", and price.

The TR link I used, (yes, I plugged in our car, but wheel size is the same as yours.) I knocked off all winter tires, tires speed rated above "V", some brands I have never hear of, etc., and whittled that link list down to about ~25 tires.
