If you are considering re-centered hummer rims, check your area. once the hummer rims are cut, they are no longer DOT approved. spacers can be used but in my opinion that is worse than a re-center. I actually had a Texas DPS officer make some comments on mine when I had them, he did not ticket me but informed me that if he saw me again he would. I got rid of them for the better hutchinsons. you would be surprised how many officers know what the military rims look like maybe because many are ex military.
The pvc inserts are great, much easier to balance. I have 16 inch aluminum Hutchinson bead locks where I made my own pvc centers using large pvc pipe couplings. They are great, balance well and make my 39 inch tall tires run smooth as silk.
I second the centramatics. they help a lot but wont do it all, you still have to put weights on them and get them as close as you can.
And you may also find difficulty getting someone to work on the hummer takeoffs, the discount tire near me will not touch them. I tried to have them put one on a spare non-beadlock rim and they clamed they could not do it because the tire was not made to go over the bead and required bead locks. I know that is bs but it is what is was told, thus if you do not have spit rims where you can mount them yourself you may find it hard to get someone to mount and balance them. Once I assembled mine I had to go to a truck tire shop to get them balanced.
There are a lot of people that like them. It is a toss up for you.
My biggest red flag that I see in your post is you want to run your family around on these tires. I would not trust them at highway speeds in vehicle loaded with family. They were build for Humvees which run low pressure and slower speeds. Not a civy truck running 75 mph with 45 psi in them.
my two cents. I have had them and will not buy them again unless I am building a non street legal off road rig.
