I personally wouldn’t go much below 12psi on the rear and definitely wouldn’t go below 18 psi on the front particularly if you have a loader on. If you are carrying a weight on the back of the tractor, I would run 16-18 psi in the rear’s. If you go too low, there is a danger of the rim spinning inside the tire and the liquid leaking out. On our AG tractors when farming, we ran 18psi in the rears all the time.
Pop a bead with rim guard in the tire? That's a gamble I would not want to take...
Another risk of running to low with Rimgard is the wheel slipping inside the rim.
I'm running RimGuard in the rears of my L2500. Installed sticker rear tires last fall (Galaxy Earth Pro).
Also running inner tubes.
Right after I installed the RG and when I aired up the rear tires for the first time, I found that just 3 PSI was enough to take all of the 'belly' out of the sidewall. The tire beads had been seated previously before installing RG. That was a year ago. Since then, I've plowed snow off the driveway once last April and graded the driveway twice this summer. All with a 7-foot LandPride rear blade. I have noticed no issues with tire slippage on the rim.
There is a lot of slope in my 1500-foot unpaved driveway - 4% to 6%. I have been amazed at the traction this tractor now has (with RG)! It will pull a bladeful of asphalt millings uphill (in 4WD) with no slippage of the wheels/tires at all. With snow, there is no need for tire chains. I usually run in second gear at 2000-2500 RPM when I'm blading...
YMMV.
I am prompted by this thread to put a mark on the rim/sidewall so that I can monitor slippage at the bead.
Thanks,

PS, Tractor has the LB400 loader on it. Before I installed RG, without the blade attached, the tractor would hardly move in 2WD. Probably not much more than 250 lbs of ground pressure at the rear tires in that configuration.

In my experience, no marks were needed to know when the tire on my B7500 slipped. The tractor stopped moving and the tire puked most of the windshield washer fluid ballast on the ground
Hi chim, Do you remember what tire pressure you were running? Obviously not enough.In my experience, no marks were needed to know when the tire on my B7500 slipped. The tractor stopped moving and the tire puked most of the windshield washer fluid ballast on the ground
FEL will be on the tractor always with a grapple in the future. will also be using a disc and a bush hog. I do have a ballast box as well. I also have a B2601 with unloaded tires and have been running 8 psi in the rears for 5 years with no problems but I figured that would be to low for the larger loaded tires of a GL6060.
From the responses it sounds like I should be safe running 18 in the rears and 22 in front.
Thanks again, everyone.
That was 20 years ago and I'm not sure what pressure was in the B7500's tires. As you stated it obviously wasn't enough. It happened in Jersey Shore PA one Saturday while helping #2 Son extend a parking lot at an apartment building.
EDITED - was #2 Son (only have 3 boys
)Attachments

I didn’t change my tire pressures at all after filling with windshield washer fluid.
No troubles, no doubts, no unexpected mess from a bead coming off.
