Tires tire pressure

[mit]

hey u all,
i am trying to find the tire pressure for the front tires for my mitsubishi d 1850 fd tractor.i checked it and it has 15 psi.ipumped it up to 20 psi i cannot find the markings on the tires the walls are old and a little cracked.at 15 psi the tires looks soft (bulges at the bottom).any help would be appreciated.

Is it 4wd, or 2wd, and does it have a fel on it. On a 2wd tractor, 30 lbs will make it steer better on hard surfaces, but you will get better steering in soft, just tilled earth with about 20 lbs in it. On 4wd tractors, you want about 20 lbs for soft conditions , too, but if you go too soft, the tires can slip on the rim. Loader tractors need higher pressures to keep them on the rim with increased loads. Hope this helps somewhat.
