that's a good idea to spin them before glueing to see if they have a chance of being right once glued!

if not you might get into foam triming to be sure it is not bunching up if overly compressed. but the new molded foams are a dream. just making sure the tire seats perfect on it's bead can take some trimming too.

if your just bashing around, jumping, and smashing corners ...
tire balancing isn't going to be what saves the most of your worn out parts.

if you have alot of hi speed sections where you see the tire bouncing , then you realy have a problem with the balance.
a little bit of low speed wobble isn't the end of the world if it balances out at higher speeds. but for sure more wear to the truck and tire if not glued well
