Using jacks to change tires

I talked to a local truck tire center about changing my tires and during the conversation he stated that he would be using the hydraulic jacks on the RV. To lift the tires off the ground in order to change them. Is it ok to use hydraulic jacks to change tires or will it hurt the RV. I have a 40 ft 06 Holiday Rambler

Find a different tire shop, fast!!!!! No way should the chassis jack system be used to lift the MH to change tires. Any time that I had tires work done, the shop always used their jacks to lift the MH.
Others may disagree but.......

Along the side of the highway in the rain maybe...only if manufacturer has indicated okay.

Had our front wheel well off the ground once and nothing grunted a bit...

But a tire shop should have proper jacks and ALWAYS lift by supporting the axle to avoid stressing suspension parts.

Them hinting at that indicates either stupid or lazy or both and more.

Place that did ours did not have a protection ring to protect the rims from scratches...we did not know of such a thing but owner came out and was very sorry about that and for delays as they had to go buy one to do the job.

Bottom line is they should know correct process and you should insist on proper and safe...locate another vendor

No way would I let them ever do that, what if they damage your leveling system? If they don't have the right tools I can wait.

Nope! Everything I've ever read, whether it's the jack manual or manufactures manual, say not to use the jacks to lift the coach off the ground. And if you do, to put jack stands under it.

My manual says not to do it.
The tire shop that replaced my tires used their own floor jacks. They did have an issue getting the jack under the front and asked if I could lift the front frame enough - maybe six inches - for their jack to fit under the frame. That wasn't anymore than what my jacks do all the time so I accommodated them.

I have had some serious arguments with shops about using MY equipment when I am paying them to use THEIR equipment. I ended up just telling them they don't work, don't use them, and pulled the fuse. HWH jacks (at least my last 2 rvs) are actually mounted in swivels and the RV will shift if something is wrong.

I didn't like the idea either I think the shop is just trying to get the job done as quick as they could but the weird thing is it is a semi truck shop so really its just laziness

Man I wouldn't do it. I can't imagine the twisting stress on the coach if they lifted just one corner off the ground at a time.

I have used my jacks like this many times. It's not a big deal.

That's better than having a tire shop put their jack on the lower control arm (Freightliner Independent Front Suspension chassis) and jack on that. The control arm bent and I had to have it replaced. I didn't notice it until months later, so I could not prove they did it. But it HAD to be the tire shop. I had to bear the $1,700+ cost to replace it and re-align the front end. If I had simply lifted the front end with my own jacks, I would not have had this problem. Live and learn...

If you set up in an RV park on a site that's not level, you may end up with the front wheels off the ground when you level up. There is no difference between doing that and just lifting the wheels off the ground on level ground to change a tire.

I recently had to have some work done on my exhaust system. I lifted the right side of the coach to give the exhaust tech plenty of room to work at the right rear. The right rear tire was about an inch off the ground. The right front was still touching the ground, but had very little weight on it. Worked perfectly.

You cannot lift just one corner, which would indeed cause all kinds of damage due to the twisting forces on the chassis. The jacking systems are designed to run two jacks at a time to lift the front, back or a side of the coach evenly.

When you run the jacks to the end they are not very stable as too much piston rod is out and has too much leverage, the thing to do is put about 6-8 inches of blocking under the jack to keep the ram from fully extending and you then gain jack stability, lift only until the tire is just clear. I have done this with no problem.

Having worked for many years as a Heavy Duty Wrecker operator and with many tire shops, if they handle Semi Trucks and Commercial vehicles, they understand and know more about your Motorhome suspension and the right and wrong way to use jacks then you as the owner do.

On the other hand, if the tire shop is an Auto type business, then yes I would be concerned about how they plan to,lift the vehicle.

While Semi Tractor/Trailer and Commercial Trucks usually don't have leveling jacks, their suspension is just as if not more complicated. To the point that lifting the frame may lift the vehicle off the spring brackets without chaining then in place.
