Is that a gut feel or is there testing you know about? I'm not criticizing as I think you are probably right, but I have been trying to find hard evidence that is the case - Andy Hollis did some testing in GRM that showed that going from a pinched tire to a wider in spec wheel on the same tire added significant grip, but that doesn't help us specifically in this case where you can't change wheel width. What I am looking for is data that shows how a pinched tire compares to a nominal width tire on the same wheel, and whether that will offset the amount of grip lost by losing 20mm off the rear tire with both options being "in spec" on the rear wheel.
