I am using no spacers for E65 wheels, and it fits perfectly. I think if your fenders are like sedans, there will be a problem in the back with spacers (i had my fenders rolled when using 295/30 tires, wich is about the same as using 275/30 and 10mm spacers). But since youre going to use so low tires, it might not, needs to be tested... About 275 low profile on 10" wheel is a different story, i think it will look too stretched, i am using a lilltle higher and 285 tire, and i think the 295 would be the right one for this width wheel and profile (but then the ET should be a little higher:-P).

Pic ftom the rear tire (its the default 10" ET24 E65 wheel without a spacer and a 285/35/19 tire):

 

Hi,

The problem with the Touring's are that it is really tight on the inside (the air suspension takes a lot more space than on the E60). This is the main reason I need spacers.
I'm running 275/30's on the rear - wider would no work out due to the cramped space.

I like the stretched look....
