Why Roadside... Now changing inner dually
Yahoo Message Number: 151841
Andy mentions changing the inner dually.  I have roadside assistance but wouldn't dream of calling em for a flat on my Jeep.  I can change the tire much faster myself than waiting for roadside assistance.  But the RVs another matter.  How do people in the group jack up the rig to change a tire?  I have a bottle jack but would be nervous that the axle would slip off the small cradle on the top of the jack.  For an outer dually flat can the inner tire (on blocks) support the rig during the tire change?  For an inner dually or the front tire, how do people jack up the RV?

A 12 ton bottle jack under the axle with at least two wheel blocks can change the inner dually. There is a risk and I tried to make it quick. Now that you mention it maybe I need a jackstand, too. The inside tire cannot support weight with the lug nuts off. A 12 ton jack has a pretty wide grooved pad to fit the axle.

How would I safely jack up to change a tire?  That was part of my reasons for getting a hydraulic leveling system.  My Bigfoot system can easily raise the wheels off the ground if I put a few wood blocks (which I carry) under the pads.  Using the manual control I would drop the pads until they begin to take the load.  Next, block the wheels on the other side.  Now loosen the lug nuts using my big torque wrench.  Raise the wheel into the air.  Remove the lug nuts.  Now the hard part - lifting off the tires and putting on the spare and outer.  Snug up the lug nuts, snug again, then put load on the tire and torque to 140 foot pounds.  Store the bad tire and head for a tire shop.
 So - I can do it safely, but I still have CoachNet, because as Andy said, there is lots that can go wrong beside a tire problem.

I carry a 5 and a 12 ton hydraulic jack, plus a big stack of blocks for cribbing the axle A long 1/2" breaker bar, along with a 48" cheater makes removal of the lug nuts possible. The lug nuts are the most challenging part of changing a tire, IMO Changing a tire, especially a rear, should be practiced at home so you can work out the bugs at your own leisure. Same advice goes for snow chains.

Lifting a rear wheel isn't so hard as you can run the good tire up on ramps or leveling blocks (same method I use for installing snow cables).
Use the two jacks to finish lifting, if needed and to add another layer of support.
The plastic leveling blocks can also be used to crib the axle, for extra security if desired.
Start to loosen the lug nuts with the RV still on the ground and the parking brake on.
Do block the un-lifted wheels.

Sure glad to have had very few flats on the RVs over the last several decades.
If convenient, Coach-Net will do the work for me.  Coach-Net has serve us well in the past.

--- Yes, they are, and what I could easily do back in the day is either a whole lot harder or almost impossible now! In my pioneering days, I could wrestle a 20-gallon plastic garbage can full of water (about 150-160 pounds) out of the back of the pickup; parked on a little backwards slant to lower the rear without dumping the can, "hugged" the can to the rear of the down tailgate, then muscled it by the handles to the ground without much spilling or slopping over.

That was then; this is now. I recognize my limitations. Coach-Net. ;-)
