What tire air pressure should be held in my YM2000? I have liquid in rears. Just air in front. The front tire say's not to exceed 35lbs while seating bead, but it looks low at that.

TNbob,

I have a 1700 with liquid filled tires. If I remember correctly; I had 30 - 35 PSI in rears. You will have to take the weight off of the rear tires to air up (at least I had to); hard to displace the area of the water with air pressure while the tire is on the ground. Make sure your valve stem is in the 12 o'clock position.

Careful!

For 4 ply rear tires the YM195/YM240 manual says 23 psi MAXIMUM for an 8.3 x 24, 18 psi max for 9.5 or 11.2 x 24, and 14 psi max for 13.6 x 16. I suggest look up your tire sizes in Firestone or Goodyear's online charts.

I think on any tractor you want to air down until you begin to see some sidewall bulge. I am running oversize 12.4 x 24 rears, ballasted with water to about 11:00 position. On mine running 7 to 9 psi the bulge is unnoticeable until I raise an implement, then very slight.

Ditto.. 35 psi sounds like max booting pressure.

I havn't seen to many rear ag tires that want more than 20 psi in them.

As for airing up off the ground?.. I've never had to jack up a tire to air it... wet or not.

Don't mean to give false info. Just relaying what I encountered while filling my rear tires (tubes in rears). When I filled the rears and let it down off of the jack; the sidewall bulge was more than I was comfortable with and would get some "tire roll" if I was driving on the side of a hill. I did not have that before I filled the rears.

I tried to air them up while still on the ground, but my wimpy air compressor would not air them up to where they needed to be. I figured there was not enough air pressure to "push" the water down and fill the void so I jacked it back up enough to take the weight off and fill with air. When I did this and dropped it back down; it looked correct and I did not get that "tire roll". I could be wrong about the air pressure, but I was going off of memory and I have slept since then /forums/images/graemlins/smirk.gif. My tires were filled to the 11:00 position (tubes in rears, no markings on tire saying what max psi should be) and have not had a problem. Sorry for the misinformation.

hey guys,
i have a couple of questions about filling the tires (again!). a) how do you know you've filled them to the 11o'clock position? b) would filling the tires help with preventing the rears from digging into the soil, or the opposite? It's been so dry here that my 1601 is just ripping up the grass and everything it drives over.. That's nice thin MA soil for me!! /forums/images/graemlins/blush.gif TIA, -art

Filling tires ads weight.. that generally adds traction. i'd look to see WORSE ripped up soil as the tire becomes more agressive.

put your valve stem at 11 oclock.. periodically check it.. when you disconnect the hose and water runs out.. you are higher than 11 oclock. when water stops running out.. you are at 11 oclock..

thanks, soundguy. it's so simple it's like a complex problem!! /forums/images/graemlins/blush.gif
I guess I'm not going to fill my tires, at least not for now...

is there ever an occassion to just partially fill the tires? Is that dangerous?

I recently had mine filled and had the same thought--fill only 1/3 0r 1/2 full and this would give a lower center of gravity to the tractor for hillsides and still give some additional traction.
The man from Co-Op who is over the gagage told me I should fill and not try the 1/2 fill idea. So I did and it certainly stops the wheel spin with a box blade in loose gravel and discing in the fields.
I wish I had tried the 1/2 fill then could have had more added more if desired.

Hey guys thanks for the info. Yes soundguy, that is the pressure warning on the sidewall about seating the bead. If I put in less pressure than 35 they look low. I was getting sidewall stress cracks at the lugs in the rears so I checked them and had 0 pressure, I put in 20 in the rears and they look right now.
