Possible trade: your 04+ 10.5's for my 9.5's?
 

I may go the 315 look all around. Anyone up to trade your rear wheels for my front ones?

That sounds like a dumb idea. Your x5 will ride like crapola. why would you do that?

actually I've heard that matching all 4 tires gives you better handling compared to a staggered setup

We can't be sure the wider wheels will work on the front given the offset, plus the wider tire will require a bit more steering effort and be more prone to hydroplaning than the narrower OE size.......

I don't think you should have offset issue as it has been done on a 4.6is. Check here

I'm just looking for someone who would be interested in switching to less expensive rubber and want to rotate their 275's. If not, I'll just buy a new set wheels, not a problem.

Bump.
