I run a extra 2-3 pounds in the front of my BX. If I don't I notice the side walls flex more when doing loader work. I also have Green Slime in them never had any problems.
Yeah agree with running a good bit on front if you got a loader on it,and even on back if you got an extra big load there.
I'm talking no loader and nothing heavier than a tiller on back in low range on dirt.
This was also just brought up in johndeere forum by somebody else,good link,that pretty much reassured me as to pressure. Gives tire sizes etc and min/max depending on load I'm assuming,their min was 20 for my rear tire size,max 31. For front it was 12-49 psi. Wouldn't think loaded tires would affect this?
