Thanks - they do look much better than the stock tires, and no rubbing whatsoever with the 275's. I actually had the dealer swap my tires so I can't compare the before/after MPG. But they handle fine and the ride isn't noticably harsh. But then I've had the same tire, albeit in a 16" tire with D load range, on my 98 4Runner for the last 10 years so I may just be used to it.
To me, the ride actually feels very nice, MUCH softer than my 98, but I'm sure it is some degree stiffer than it would be with a C rated tire. A lot depends upon the tire pressure you run in them. But then again, I've consistently got 60-70K miles out of the last three sets of BGF AT's I've owned and have never had any problems with them - they always wear perfectly, and I like that.
