Kinda hard to say, it could be a lot of things.

First things to check could be:

- Wheel/Tire balancing
- Wheel Alignment

If you have a trusted mechanic, have him check it out. I say trusted because, if not, all of a sudden you might have other things needing repair too! :D

Good luck! :thumbup:

Absolutely. Send them to me before your X is ruined. I'll send you my stock sized wheels and tires in return.

Just trying to help.

good try carlgo and weasel...and dang funny too! the right front was out of balance by an ounce...

Thats about 30 grams. So yeah, that would cause a lil shimmy. So now you're back to riding smooth :D

We replaced the front tires this morning, with 265/50/20 and kept the rears with 295/45/20. All the tires fit the rims well, and all tires have wheel well clearance.

The overall diameter on both sizes are now identical at 30.6" and the revs per mile are also identical at 679. I could not figure out your formula for determining the rolling diameter, but do know according to the revs per mile and the overall diameter they will mathematically get the same rolling diameter, for each size.

Here is the specs for the Yokohama Parada Spec-X:

I hope my "crisis" is avoided and I can get on enjoying the X5 ride...:D

Hi I am sorry to message out the blue but I have the x5 and want this setup and just wanted to see if you remember if you had any issues with the transfer case or gearbox thanks
