I'm not even looking/ considering your truck I'm simply looking at the rim itself not even the tire. The larger the offset the more the mounting face changes from the center of the rim. Now specifically on yours it would be -44mm, roughly 1.75inches now that's from center so that plus half your rim 6inches, means your mounting face is about 7.75 inches inset from the front lip of your rim, so back out some for the thickness of your 'spokes' so to speak call them 1.25inch means your rim should be revealing about 6.5inches of 'dish' yours visually looks like about 4 which is closer to the -24. At any rate if this raises a flag to you and you actually paid for the -44 and got the -24's, you could probably get the -44 for the mixup if that's the case which also would give you that extra stance your after. To confirm the size you really have just pull up your wheels manf spec and then go measure to see what offset it matches.
