why wider tires on rear of x5?

You guys are lucky, out here in cyprus the most exciting ride would be wehn you squash the odd snake or avoid the odd sheep that has deserted the flock, apart from that it is pretty cool come to thinkof it, got the highest number of cars per head of popluation in europe and not a very densley populated place so you can push the car nicely...and enjoy it....ok so fat tires at the back look better is the conclusion plus more traction due to larger surface area in contact with road...cool
