Bonjour Pedro

Yes the rims are still legal....... handle them with respect and they will outlive you.

Standard size tires should be 900x16 and should have tractor thread bars that are mounted in direction of travel..... known as "Directional threads".

The only copies currently available are sold by Wallace Wade of Texas and come only in 10:50x16.... they will fit...look awful good and a bunch of us have been using them.....current price is $242 US plus custom plus shipping.

A good alternative is the standard US bar thread still manufactured by repro companies....usually 8 plys 900x16 and can be imported from the US at about $200 each. You will need new flaps and new tubes as well.

If you current tires still hold air and you can roll the truck around while working on it.....don't rush to buy new tires..... do you dirty work with the old tires...... oil..grease...paint will get on them and it might as well be the old ones that are getting dirtied.

Besides....... I would strongly suggest you will need to remove the wheels off the truck....... deflate the tire..... and undo the 8 big nuts that holds the rims together. You may decide that spending hours breaking your back is not worth the money and take your rims to a rural tractor shop and have them remove the tires from the rim. From my experience you will have 40 to 60 years of rust welding the bead of the tire onto the rim and only a professional with hydraulic tools can do it fast and safe. Then take the rims home.... you will need to scrap the inside or even use a air powered needle gun to remove the dried up rubber beads stuck to the rim........ and consider sandblasing them all around before painting them...... a good high gloss oil based paint ( at least two coats) on the inside will greatly assist installing new tires.

Look for deep rust pits on the inside of the rims....... suspend the rim halves from a rope and hit them with a hammer..... if they ring like a bell they are not cracked. Make sure all your nuts and studs are good and clean up the threads.

Now you are ready to install the new tires.

Don't rush....do it once do it well.

You might want to do a search on MLU for tire related previous discussion.

You are on the right track by asking questions.
