If you go this route, BE SURE the BB's are copper-coated lead and not steel. The copper flash WILL wear off quickly and the resultant ferric oxide mess will alarm youI used BB's.
Get about 1oz of BB's per 10lb of tire. Most tires are about 120lb or so, so figure about 12-16oz of BB's. Much cheaper than Dynabeads.

Or, just use lead shot (which, BTW, also will eventually turn into a mass of corrosion)
Even though it's hard work, rotate them often if you put a lot of road miles on them. The worst enemy of these big tires is uneven wear.tires are going to be near 3500 by the time I'm done and don't wann to ruin them
I run my 14.5R20's at about 50-55psi, but they're rated up to 80psi.Since the topic came up though, what is a good PSI to run? In my 33" Goodyear MTR's on my Tacoma, I push 55 or so (max load PSI is 60 or 65), and the wear is perfect! But, if I hit rough patches on the road, I dribble like a basketball!
That is how I figured out my optimum pressure. I took a big piece of chalk - the kind kids draw on the sidewalk with - and 'painted' a strip across the tire. I started at max pressure and adjusted down until the contact pattern looked good. Unloaded, my 416 DoKa seems to like 35-40 PSI rear and around 50 psi in front. This is with Conti MPT-80's with the lowest ply rating (I think they're 8 ply).I adjust pressure until I see reasonable road contact across the tread.
