Are you asking a bolt pattern question?
Or a tire size question?
The tires will be about an inch shorter
overall. About a 5% difference in diameter, speedometer reading, etc.
Astro I think you forgot the 55 series would be upped to a 16"
So they will be basically the same O.D and circ.
I also looked at a set of Avid Ascend and the reported Diameter diff for actual tire was only 0.1" shorter than current.
And that within the tire wear range - so not noticeable.
Does the OP know if they have a 5 lug pattern and what the bolt circle is?
And TPMS tech may be a concern.
