I know someone who put 275 on the back, but it's snug and rubs. And that's using a R6. The R7 is much wider. I don't see how it's possible to make it fit without major issues.

Does my earlier answer not count? 
Evan answered this too. Call Buckley, CCW, Jongbloed, or Accumoto. Those wheels work. Some work on your wallet more than others.
R6 275 (15" and 17") fit all day long with the above wheel brands. But I too have heard that the R7 275 might be problematic. You might play it safe with a 245 until you know for sure how much room you have.

Agreed. It sounds ridiculous in a good way. The shifts are lightning fast too.
Astroman: It counts but since R6 are off the table, R7's should be the topic of discussion now 
I gave up and ordered a set of 245-15 R7 rears this morning. The R7 in 275 was just too big and I ruined the tires as there wasn't enough room for clearance. The shoulders on the R7 are massive in comparison to the R6. Even monkeying with it, I don't see how could get the 275 R7 under stock fenders, since the R6 in a 275 rubs some.

Does anyone have an actual measurement of the width of the R7 in 275 vs. the R6? I see that the data sheet published by Tire Rack shows the tires to have identical section widths (10.8 inches), but we all know that the published data is not always accurate.

Is Hoosier still making a 245-40-15 in the R7?

Just checked and the 245/40/15 (83W-$251) has the same rolling dia. as the 275/35/15 (82W $289) so gearing will be unaffected. I bet that mounted on the 9" rear wheel you will see about 10mm difference from a 275/35/15 R6 laying right next to it.. AND save some $$. Run 225 in front, 245 in rear, plenty of grip.
