Changing all 4 tyres at same time - jacking advice

[hiker]

Hi there - am about to replace all tyres at once and a quick chat with my local tyre place indicated that for air suspension vehicles, they recommend raise to off road height and remove the fuse before driving the car into the workshop. They want to raise the car on a hoist with all wheels lifted, thus steamlining the change process. Has anybody been through this process and can share their experience or words of caution etc?
Thanks in advance.

You just drive it in as normal, put the four pads under the chassis at the lift points and lift. All wheels will drop to full droop, remove wheels, change tyres.

There’s no need to treat it differently if all four are done together.

It’s different if you’re removing a single wheel on a jack.

P38 (with full EAS still), drive in, lift and change tyres as per any other car. The only thing I got them to do different was cycle through all different heights and drive it around the block prior to doing the wheel alignment.

[DiscoJeffster]

Yes good point. Once you lower it down, the suspension will complain it’s not in normal ride height. Re-select normal ride height and it will settle back to normal height.

And ask your wheel alignment person to put the suspension in Tight Tolerance Mode (TTM). If they look at you with a blank expression go elsewhere. If you were in Melbourne I'd recommend Edgars Tyrepower, Notting Hill -- they know about TTM and their alignment improved the handling of my D4.

No one mentioned a wheel alignment!!! If we’re talking wheel alignment as well as tyre fitting then yes, as Scott says, you need to use TTM and take it to somewhere that knows LR vehicles.

Too many cowboy tyre fitters out there, i put on my spare set and drop the wheels off so no rattle gun and no jacking off the EAS compressor.
For a single wheel at a time, not even a blink at jacking one at a time.

Never heard of this request.
Drive in as normal.

Make sure they hoist off chassis, not air compressor/ air tank.

Load of rubbish from the tyre place. Just drive in, hoist up and replace. No issues. If they don't know, take your business elsewhere. EAS will simply droop as the car is lifted, all you need to do is reconfirm your height once back in the car. Only if you are doing a WA as well, then you need to set thr car into ttm as others have said. If you leave it in off road height, thr slignment will be worse than when you drove in. Again, if they don't want to know....

Not quite….

The fuse part is rubbish - may just be the company don’t want moving things!

However, the correct practice to lift the vehicle is to place it in Offroad height. It reduces potential errors when it’s dropped.

As for offroad height vs wheel alignment - in the OPs post this is purely for a 2 post hoist lift to do tyres and is actually the correct way to do it (less the fuse).

Agree 100% that the vehicle should be at stock height and TTM for wheel alignment.

And I have no issue with them wanting to remove the fuse either. They are responsible for managing safety - not the car owner - and if they have had experience with the suspension adjusting when working on the car then good on them for being extra cautious. Even if it can’t adjust the height with all 4 wheels hanging free or it is unlikely to cause a problem, all they are doing is isolating a potential energy source that could cause movement of the suspension.
