Can Air Suspension be used w 1 or 2 inflated 3 ton liftbag to change wheel?

SIMPLEX Lifting Bag,3.1 Ton,9x9 - 46C533|B3A - Grainger


After putting the parking break on, can the air suspension be raised to max, then insert one or two inflated 3T lift-bag under one of the lift points, then lowering air suspension down on to inflated lift-bag to change the wheel or flat tire if u happen to have a spare wheel/tire with u on a long trip, to reduce wait time for a ranger?

I think the tire will still be in contact with the ground, so it won't work.

I don't think there is enough capacity at the top end - it's not like the old Citroen suspension which could do this party trick

Be an interesting experiment though

The lift-bag could have a solid spacer added underneath to take up the space. The lift-bag will be inflated 100%. Note the one I listed was just to show what I was thinking of that would be none bulky to store in the frunk and low weight. To test this one could stack wood to take up the space after raising the air suspension to max.

I believe that the system will strive to maintain contact with the ground on all 4 tires regardless of the suspension setting.

Ouch - those aren’t cheap

That is what Jack mode is for. To prevent the suspension from self leveling.

Seems like the method the OP describes would prevent the use of jack mode until the final step, which would allow self leveling to keep functioning while you were lowering the suspension on the bags.

I don't understand.

The point of a lift bag is to 'lift'. You take a deflated bag, inflate it and lift something.

The problem is that you have a small area for lifting under normal circumstances, so can't possibly see how this would work.

Use a shop jack already.

Shop Jack does not travel well with a spare tire

u could use the tire air pump to inflate the liftbag. I was trying to let the car do the lifting work then insert the liftbag already inflated.
