I love the look of these wheels as I put them on my older E39 in 18". However, my question concerns tire sizes for the 20 X 10 wheels on my E70. I know that I could go 275/40/20 Toyos all around. But will 315/35/20 tires fit the 20 X 10 wheels for the rear and let me use a staggered fitment? Most wheel/tire sites, Tire Rack and Buy Wheels Today, show that you need 20 X 10.5 to make it work. But has anybody tried it?

Thanks a bunch in advance!
