I repeat: a 275/80R22.5 and a 295/75R22.5 are the same size. They can be used side by side on the same duals. This is not a theory. This is extensive personal experience: I put over 70,000 miles on a truck (Ford F-650) that had one 275/80R22.5 and one 295/75R22.5 (two Michelin, one Goodyear, one Bridgestone) on each rear dual. There are probably half a dozen tractors and twice that maany trailers at work with 275/80's and 295/75's on the same pair of duals.

This has already been explained to you why you are incorrect.

The math supports Jaraxle:
275mm x 80% = 220.00mm
294mm x 75% = 221.25mm
------
difference 1.25mm (~5/1000 of an inch)

Forget the math...70,000+ miles of road time supports Jarlaxle. A 295/75R22.5 and a 275/80R22.5 are the same size. Period, end of story.

They are not the same size, they are close to the same size.

Yet again from the top: a 275/80R22.5 and a 295/75R22.5 are the same size. They can be used side by side on the same duals. This is not a theory.
