BFG makes the AT in a 31.5" 265/65x18 that might fit in your X5 fenders. If not, try looking at Tire rack for sizes like 265/60x18 or 285/60x18 depending on your x5 rim width. I think the x5 is smallish oem tire though, maybe 29" but if so, that's the same as a Discovery 3 oem which is 255/55x19 or 255/60x18. You might try the Nokian website to see what sizes the WRG2 suv comes in. They have some that will fit the x5 just fine and it's a great all year, even in snow, tire.
