real world tire pressure

[O~o\-HT]

I have been trying different tire pressures on my 2210D. <B><s></s>29 psi<e></e></B> seems excellent in the front and probably creates less stress on the drive train than lower pressure.
I found <B><s></s>12 psi<e></e></B> in the rear gives my best traction with a slight bulge under load.
I am running a 5' vtek bucket up front and either a 5' box scraper or 4' bush hog in back.
My concern is the front to rear tire diameter ratio. Am I wearing down my drive train with these psi's, or is 12 psi in the rear ok?

The 195/340 operation manual gives 12psi as minimum inflation for rear tires. I think you are good with 12psi.
