WAIT.
You are going to have 2 tires the same outside dia, one random tire at another outside dia and yet another random tire at some point at again, another random dia?
BRO didnt we go over this already?
go do some math, find out how many RPM’s even 3/32’s of an inch difference will make in each gear at XX speed.
not only will your center dif hate life, but the front &/or rear will too!
Sell them to a RWD guy and get 4 NEW tires. If you cant afford $800 on 4 tires, you cant afford twice that for a diff replacement.

Ernie, once you get a full set you should sell them. You might even make a little money. Winter is right around the corner. Put the money toward snow tires.
