Loaded the tires on the S470D Buck today.

9.5 x 18 Ag tread. Took just under 14 gallons each tire. Used Propylene Glycol (RV antifreeze) and water 50-50. Got the antifreeze at WalMart on clearance a few weeks ago for $3.50/gal. Read somewhere about using a 2 gal tank sprayer for pressure, and that's what I ended up using. I already had the adapter/bleeder valve from Tractor Supply. I took the wand & hose off my tank sprayer, and installed the supply hose temporarily removed from a garden hose reel. I needed to use a small piece of that clear poly hose as a bushing between the hose and the nipple, and tightened it to the nipple on the tank sprayer with a hose clamp. Got each tire off the ground with my floor jack, rotated the tire till the valve was at 12 o'clock, and removed the insides from the valve stem, let all the air escape, then screwed on the adapter. It's good to leave it all loose until it's all in position, with the bleeder button on top. Then, I just poured in 2 gal of anti freeze, pumped it up, let it run in, then let the excess air escape from the tire by unscrewing the pump from the tank. This created some syphoning action which helped. I really didn't need the bleeder valve on the adapter with this set up. Just had the seat flipped forward, and the spray tank sitting on the tool box. While the tires filled, I tinkered on other stuff in the work shop. One wheel has a tube; the other does not, so the one with the larger valve stem hole filled much quicker. I did not stay right on it and hurry, so it took about 5 hrs. If you stayed on it, it would take about 2-3 hrs. Good project for a rainy day, but the rain has kept me from trying it out yet. I calculate it added about 115 lbs (13.75 gal x 8.35 lbs) per wheel, which should lower the center of gravity and add traction.

That was a good "rainy day" project.

The rear lug tires on my Buck have finally rotted out to the point where I have to replace them. I can't seem to find anyone who has the same size and I don't want to get into the same situtation I have on the fronts where I bought replacements that don't really fit (dealer assured me they would be fine) and go flat between uses. Any idea where direct replacements might be found?
