I use the ATV for everything from moving the tow dolly to pulling cars to playing in the snow. The steer tires are shot so I ordered up a new pair. I have tried everything but the chainsaw to get the old ones dismounted. May try that next unless ye GRM world has suggestions.
This seems like the right place for this...
Shotgun?
cutoff wheel. split rim, throw away, install 2 piece rims.
thats what i did with mine after fighting for them for hours with tire irons.
Remove valve core, jack up on wheel on truck, set atv tire on its side under truck wheel, lower truck onto atv tire?
Are you trying to break the bead? I use an old crank bumper jack. A ratchet one will work too. There are hand small wheel bead breakers you can buy. 4 tire irons and some help will get the tire off the rim
I had one set of very old tires that wouldn't come off of split rims. I had to burn them off. I do have a chainsaw set up to cut tires.
I made a ghetto bead breaker out of a length of 4x4 with a bolted on wedge, also made of 4x4 on the bottom. Stick one end under a truck, the wheel/tire under the wedge, push down, pop.
Then lube it up w/ KY jelly (seriously, I demounted and mounted scores of motorcycle and kart tires w/ KY)and lever it off. One of the tiny handful of genuinely good Harbor Fright tools are their huge-ass tire levers. Big tire levers are like big hammers; used correctly they do the job in one economical motion and are in reality ~less~ likely to damage things than flailing at the wheel w/ small ones.
