KenB,
First off: if you have a FEL, you MUST fill your tires. My 3510 has the same frame and loader as the 4110, and it was VERY tippy without loaded tires. I don't have a backhoe on it, but did have a heavy 3ph 66" tiller on back for counterweight.
My 3510 was delivered recently without anything in the rear tires. Of course, I didn't think to ask the dealer to do it.
I filled mine with windshield washer fluid, 27 gal each, got it onsale at local automotive place (.88/gal). This was cheaper than 55 gal barrel- I called 2 different places for quotes.
They were R4's and are a little smaller than the 4110, I think...
EXTREMELY EASY to do. My 3510 R4s had a threaded valve that could be removed instead of the valve gut. This gives a much larger hole for deflating. When deflating, I stood on edge of tire and bounced a few times (did I mention we took the tire off and laid it down flat with the valve up first /forums/images/graemlins/grin.gif).
The bead broke with this minimal effort. I leaned with my knee on the edge of the tire, two of us poured a gallon each at the same time until 27 gals in the tire.
To reinflate, we reinserted the valve and valvegut, used a high volume nozzle, and wrapped a ratcheting tiedown around the tire and tightened it. Also wrapped a small piece of garden hose around rim and used some "tire goop" (looks like grease) that my grandfather had.
Once the tire sealed against the rim, filled until bead seated, then adjusted air pressure to spec.
About 20 mins per tire, max. including dismount and remounting using air tools.
Good luck.
