You will never get all of the air out. Just start with breaking the seal between the tire and wheel, roughly 0psi without pressure on the tire....
Ha, that's cheap and alot of work.
Easy way is
-support car so wheels are off the ground.
- remove valve cores and wait awhile.
- insert valve core and fill with nitrogen.
The legit way is similar only a machine puts the tires under vacuum and fills with nitro. Takes forever unless using step 2 from the cheap way.
