Tires Bumping low speed "Tire Balance needed"

[beach cart]

I have a 2007 TXT 6" lift kit with 22" x10" Duro scorchers. Tires bump at very low speed just taking off. I have waited to post this doing test drives. I checked joints, bearings, all tight and adjusted and front alignment. Do I need to have them balanced, seems balancing not needed by many threads. Will changing front to back both sides help. Any input would be appreciated.

check air presure maybe to mush or not enogh some times you just get a bad tire

The recommended pressure is 25 max, what is the right pressure in your opinion for road travel, even at 27-30.

Have the beads broken and turn the tire on the rim 180° and air it up again. Sometimes both the tire and the rim have a little runout and doing this may help to true it up.

Is it all the time or just when you start the day with the cart? There is such a thing a "flat spotting". More common in bias ply tires but radials can do it too. Usually just getting the tires warmed up takes care of the issue.

It is worse befor the tires warm up, but duro atv's are bias tires I guess. I can't see where balancing would help, but i'd sure like some feedback from some of you that have experience with the ride of a lifted cart. I don't expect it to ride smooth like a car, just learning what is realistic.

I just looked them up. That's a pretty heavy lug on that tire. I don't mean to insult, I assume they are mounted in the right direction? Are you driving on pavement,hardpack, sand what kind of surface?
How old are these tires? Is it possible they are "cupping"? The more I look at that tread design, the more I'm thinking: At low speed, that tread would seem to bump. After you get moving, the tire is going to stretch or lift a bit. That will mean less of the side wall and more of the center is the contact patch. Could it be this is what you're experiencing?

I am riding on payment only, I looked at the direction and it is right, I tried a test the other day to see how much of the tread sits and its less when first going, after driving for awhile I watched the cart up and down the street and the tread does widen out some. Your idea makes great since, but will bothering with balancing help.

sorry about the dumb payment instead of "pavement"

I'm going to assume these are fairly new tires. From that perspctive, I would say no, don't bother with the balance. I think with more use the new tires will, "shave", the edges of the lugs and reduce the bumping you hear and feel. In other words, it's the sharp edge that is causing the issue. Once it has rounded off a bit, it should disappear.
