I thought they were 335 too but they look like 20's not 19's...

Well, I will admit that there is a possibility I'm wrong, and if so, it will be neither the first nor the last time that happens! However, those sure look like 20" wheels to me, and I do think they have the darker inside - it's just hard to tell in that lighting. Try enlarging the pic and see what you think...

If you look at the tire width - its easy to see they are 20's.

Take a look at the X5 in these pictures:

It has the 335 wheels. I think that confirms that the X5 in this thread has 336.
