Well, one of my back tires leaked down and a buddy at work said they always over inflate their tractor tires for awhile to thoroughly seat the bead . He said he had 35lbs in his.

I just aired it up according to what the tire had on the sidewall, which was 20lbs.

Opinions?

If the seal to the bead isn't broken, I air up to operating pressures. If the seal has been broken, I will put enough air to seat and then back down to operating pressure.

I always refer to the sidewall rating,because someone spent good time etching that info into the tire mold.

Over-inflating momentarily to get a tire seated after the bead has broken is one thing. That's typically how it's done. Running a higher pressure with hopes of fixing a bad seal is not fixing the problem. How old are the tires? Any rim damage? Maybe the valve stems are just leaky?

The whole tractor is brand new in December (or was it November?) Front tire leaked down, so I had them tube both the fronts. Now one of the backs leaked down.

Unlike a car wheel tractor's don't have the raised lip that the tire bead needs to get over to seal. I'm not sure if adding more air is going to help it seat since the outer flange of the wheel is what stops the bead. Whether you hit it with 20 psi or 50 psi it's still going to stop the tire bead. If you are having issues with the bead leaking then a sealant along the sealing part of the tire may help.

I had one of my front tires get low. I noticed it low and just thought once back up the the house I'll throw some air in it. I never got the chance. I was in 4wd and when turning the wheel slipped just a little and just like that the bead lost it's seat and it went flat. I drove back flat, aired it up, and now check the pressure every so often. Like I said, because the steel wheels don't have that safety lip that car wheels have it takes very little and the bead just slides right off the wheel.

I'd look further. Valve (core, or heaven forbid, Chinese valve stems), possibly flawed rim, or maybe it just sat/run low for awhile allowing crud/rust between bead/rim...
