Question about tubes for 395/85R20s with stock rims. - Steel Soldiers::Military Vehicles Supersite

Alright, I've been reading some other posts about mounting 395/85R20s on stock deuce rims, and I'm a not sure which tubes I need. I've seen people saying they used stock 9-20 tubes with these tires, 11-20s, 12.5-20, and 13-20s. What do I need? It seems like the ideal setup would be the 13-20s, but if I can save some cash using smaller tubes, I'd like to. The M35 only gets driven a couple times a month, rarely more than 50 miles a day, and normally less than about 2,500 lbs of cargo. If the only real advantage to larger tubes is increased load carrying ability then it doesn't really matter to me. I just need to be able to go down the road at 55 mph without losing a tire.

Also, my brother and I are fairly mechanically competent, and we'd like to try to mount the tires ourselves. Do we actually need specialty tools or will prybars and hammers get the job done? The local Ag tire place said it'd probably cost about $350 in labor to mount 7 tires.

Thanks

You will be able to do them yourself with hand tools. The CORRECT tube to use is a 13/14r20 tube, make sure it is a radial rated tube. They are not cheap.

I got mine from here:

If you mount them your self be extra safe when you inflate them they can KILL you!!!

I can get 11-20 tubes from a 5 ton for free (assuming I buy 14-R20s for my 5 ton), because I already have the combat rims for that. So I'll have 11 11-20 tubes sitting around. Couldn't I just use those? Does anyone who did use smaller tubes (9.00-20, 11-20, 12-20) have any problems? Prone to getting flats, poor handling, something like that.
