2putt,
I'd seriously surprised if there were any interference problems with that little of size change in tires. With such a small amount of increase in any of the dimensions, I'd bet my house you're gonna no issues at all. A while ago, as in this time last year, I was in need or new tires. I had the junk Michelin 255 80R 22.5 XRV tires and they were cracked and shot. So, I wasn't about to make the same mistake the previous owner did and, I started shopping around and looking at what else I could use.
Well, long story short, I came up with some 265 75 22.5 Yokohama RY-103 tires and, like your comparisons, the size difference in any and all dimensions, was minute. I've had them on for almost a year now and, couldn't be happier. Not one single bit of clearance interference anywhere, at any time.
