L3400 front tire problems

[Oldpath05]

I'm L3400 site jumping, and tires will be on my agenda sooner before later, my front AG tires starting going flat the first summer I had my tractor, when I began moving dirt, down they'd go, I reseated them several times and would not hold air for long, then cold weather came with snow, and that was the last time they went flat, took both of them off the rim, clean them up, and put tubes in them. That was in 07, since then went flat twice, once with a nail, and once when I hit a rock just right and broke the valve stem.
Now with 600hrs. my tire tread is getting down and the rear tire are weather cracking, not sure what the brand they are, but seams to me they shouldn't be weather cracking yet. The tire size are 11.2-24, rear and 7-16 front AG, I wonder if I can get a wider tire on the same front rim with out changing the diameter?, a wider tire wouldn't sink in the ground so easy.

I think the next size up is 8.5x16, You would have to go to 14.9x24 on the rear to match the ratio...
I have a set mounted on rims ... BUT you are too far away.

What was the difference in air pressure on the tire sidewalls compared to what kubota said to run when a loader was equipped?

I don't want to go up a tire size on the back, I think I'm stuck with 7-16 on front, unless the R-4s are the same diameter, but then I would have to buy different rims, and if they are a little bigger in circumference, I would then have to but R-4s for the back, but I want to keep AG's on back, I think they get better traction in mud. I just wish 7-16 AG's had a wider tire to chose from, that would be an 8-16 wouldn't it?
