I thought the guides are installed according to what tire you use. If they're set for the 10" wide 24 tire, it'd be too narrow for either of the 25's. The tires they sent you were used on the Bigfoot 6 wheeler. The 25x11.5 was the standard tire for avengers. It is taller and narrower than the 25x12. New avengers should have the new argo tire, not the rawhides they sent you. But they are more $ than the 24's. Or to put it another way, an avenger with the 24's cost significantly less than an avenger with the new 25" argo tire(not the goodyear rawhides). I would think you need tracks made for the 25's(longer). Did they take your 24's back?
