Topic: Jack for changing flats?

Posted By: jpratt2 on 04/03/17 12:19am

Hi all: New to this wonderful RV world. Just bought a '98 Bigfoot Garage model (29') on a Ford E-Super Duty chassis with dualies.

What do you all use for a jack to change tires? Bottle jack? Floor jack? Forget the jack and call the nearest truck tire guy?

Seems the sheer size and weight of this beast would make self -changing a risky adventure.

Welcome to the forum.
Buy a Roadside Assistance policy. The most popular are Good Sam and Coach-Net.
They will send someone to change the tire for you.

Also, check your RV insurance policy, maybe you are covered.

To answer your question a bottle jack would be easier/smaller to carry. But a floor jack would probably be easier to use. Your call. [emoticon]

And, check the age of your tires. RV tires usually age out before they wear out. Most replace the tires at 6-9 years.
Monitor your tire pressure, that's important.

Don't hesitate to ask questions on the forum. Someone will have the answer.

Enjoy your travels.

Haven't had to use it, but I plan on using truck jack if I'm in a hurry, otherwise call my roadside service co.

12-ton hydraulic jack with the double-extending piston. Allows jack to be short and get under the axle when the tire's flat, yet extend enough to clear room to change the flat. I carry that plus a short jack stand for extra support, a truck-sized 4-way wrench AND one for the nuts on the wheel simulators.

I'd hope for professional help. Or somebody to help me. Finally, change it myself and I've done it before. I'd just hate to have a service truck roll up and find he'd lost the right socket, had too tall a jack, etc.

A whole Class C doesn't weigh near 12 tons. But, much less than a 12 jack is too hard to pump in the awkward location on the axle to change a rear tire.

This guy. About $20 more than a single-acting 12-ton and very much worth it.

Bottle jack and scissors jack. If it's the outer tire on the rear, I use my leveling blocks under the inner tire.

Good luck!

I use (well, I hope not to use) a hydraulic bottle jack; I believe mine is an 8 ton version. I also have an E-SuperDuty chassis. For the lug nuts, I just use a socket and a 24" breaker bar, which is plenty of leverage to undo any that are even reasonably close to the correct torque of 140 ft-lbs.

With this year and chassis make certain you have and use wheel chocks before jacking up one of the back wheels. The parking brake is on the driveshaft, so when one end of the back axle is raised off the ground there is no braking action on any of the wheels from the parking brake. (The differential will allow the wheel on the ground to turn one direction and the wheel in the air the other direction.) Wheel chocks should, of course, be used whenever you jack up any vehicle, but are rather more urgently needed in this case.

In general, though, I'm not sure the weight makes it vastly more risky than changing the tire on a car. In either case, if it comes down on any part of your anatomy, you're going to have a very, very bad day.

Use a bottle jack, but you might need two. One shorter (say a 4 ton) to make sure you can get under the axle, and a 2nd stronger (12 ton) that is usually taller. At least that is what I had to use to change my sisters tires this last year.

Just make sure that you check whatever you get to make sure it works before you need it.

And in regard to those that are proponents of roadside assistance, I would be cautious. Great service if you are in town. But there are times when it takes forever for them to get to you. My sister had 3 tread separations last year (which can be a whole other subject). Twice she called roadside assistance, and had to wait over 3 hours each time. I am not sure why you would be willing to wait that long when changing a flat should be a 15 minute ordeal.

Even if you are not physically able to do it yourself, if you have the equipment, a good samaritan will possibly help you out if you have the equipment to change it.

I like a low profile one that I can get in a tight spot. MY Class C is fairly close to the ground One like this one fits the bill

I use a low profile 30 ton bottle jack. Overkill and works perfectly.


Posted By: Camping Woody on 04/03/17 09:09am

I carry an 8 ton hydraulic jack and a large 4-way lug wrench with me. However, as a related question, does everyone carry a spare tire?

My new MH does not have one coming with it and there is no provision for mounting it under chassis. We don't like how the bumper mount would look, so we aren't going that route.

I can jack it up, but without a spare, why bother?

Very leery of doing this. Larger vehicles have a Stud with a Lug over it that tightens onto the INNER wheel. It's usually tightened with a Square Socket. Then the Outer wheel goes over that Lug then a large Nut secures the outer.

On the Ford Class C's, and I believe most other light trucks, both wheels slip over the studs then a Nut secures both wheels at once. Leaving the truck standing on one wheel, no nuts holding it, risky.

Probably won't come down, at least on level ground, but if it does, it's very likely to damage the studs and maybe the hub and wheel. I wouldn't do it.

The 4th post down (from j-d) is the one to get, as it goes both LOW to get under an axle or spring mount and HIGH to get the tires off the ground on a soft jacking surface.

We've carried that very one in our Class C for years. The "12 ton" spec is not the important part of it ... it's the minimum and maximum heights that it's ram extends that is important.

Road Side Emergency Insurance (Coach Net)-Cell Phone-No Spare. Pretty standard for a heavy Class A. Replace them all after 10 years no matter how good they look.

I took a bottle jack that I had and added a remote hand pump. I didn't like laying under our mh while jacking up the rear axel. And it's much easier to operate that pump while kneeling next to it rather than laying under the mh operating the bottle jack.

When I first saw the post, I was going to reply. Same as you, both wheels are sandwiched together on the same studs, with the same lugnuts. Take the lugnuts off, and BOTH wheels are now loose on the studs. The way my Sprinter axle is set up the hub centric wheels have just enough hub to seat on and not an extra bit. Would be an extremely dangerous thing to do what Pastorbill is suggesting.

I notice from reading pastorbilv's profile that he may to be towing an RV with an F350 dually pickup.

Jacking up the rear of a dually pickup tow vehicle to fix either an inner or outer tire in one of it's dual sets is a whole different, and easier, and less dangerous proposition (even if you leave the TT or 5'er hitched up) than trying the same on a rear corner of a Class C (or Class A) motorhome . There's way less weight on the duallies of a towing pickup than there is on the duallies of a motorhome.

It can be very difficult to loosen lug nuts unless you have a lug wrench plus pipe extension to break them loose. Using a bottle jack on soft dirt/gravel to lift an RV enough can be dangerous. Best to wait for an emergency road service unless you are well equipped and know how to change tires safely. Tell road service about whether you have or don't have a spare wheel/tire. Carrying a spare loose in your RV "trunk" can be dangerous and inconvenient. Have tires checked for serious side wall cracking especially after tires are five years old by date codes on tires. If you hear or feel steady thumping, stop and have tires inspected for tread separation. When a tire comes apart, flailing steel belts can seriously damage underside parts of the RV and you might lose control.

I use the 2 stage bottle jack that came with vehicle.
Remember to chock tires across and also diagonally from jacked tire for safety.

What is a 'remote hand pump' Dusty


Posted By: Dusty R on 04/05/17 07:25pm

It's a hand pump with oil reservoir and is connected the the hydraulic jack with a hydraulic hose. Those pumps are used with knock out punches, and other uses. Google hand hydraulic pump. Harbor Fright and Northern Tool are two places.
Some where on the net I learned how/where to drill and tap a jack to add a hi-pressure gauge. You can hook a hose in place of the gauge.

One day 3,000 miles from home in my mother-in-law's driveway, I decided I would rather rotate the tires on the Navion/Sprinter than spend time indoors. The provided jack, in my opinion, was marginal at best for lifting the rear axel. After that, I opted to carry a jack from an F-450 work truck. A fleet service was mandatory for the work truck and employees were not allowed to service the vehicle. After the second time rotating tires on that RV, I started to think about letting someone else wrestle the tires.

Ha. That's funny. The roadside guy probably has one of those jacks in his toolbox.
