What is the properly way to DIY change tires?
I've been jacking up each corner one at a time and just changing the tire. Obviously, this is not the textbook safe way, so what is…?
I assume jackstands are needed but what is the procedure exactly? I can't figure out the logistics as the jack is taking up where the jackstand goes, unless one needs 2 jacks to do it right? |

I assume you mean change a wheel (e.g between winter & summer sets), as most owners probably wouldn’t change a tire/tyre at home?
I just do one corner at a time on a hydraulic 2 tonne jack and a 18v cordless impact wrench. |

There are jack points in the center front and rear - only way to get jackstands in place. I get front jackstands in first, then the rear. Reverse order to get the car back on the ground.

So for a wheel change, where I'm not getting under the car, I'm not too worried about safety. I will do what is convenient. If I'm rotating front to back on same side, I just jack one side up at a time (pick a corner) and swap the wheels. If swapping left/right, I do the center point and lift the entire front or rear, and swap the wheels. I try to do wheel rotations/changes when I do some other work which involves putting the car on jackstands, but if all I'm doing is swapping wheels, I don't use jackstands.
Yes, there should be a jack point in the center of the car, both front and rear. No need for a service manual, you can locate your center jack points by looking and using some common sense. I'll let someone more knowledgeable about Z's chime in, since I've never looked under an E89. But I'll describe what's under the E86. The front jack point is a round "puck" pretty deep under the nose, near the oil pan drain bolt. The rear jackpoint is the location where the 2 cross-members join (but NOT the differential cooler!). It's not nearly as deep in as the front. |

I got mine from Costco for $1000 shipped. I agree, if you don't do any maintenance and only the occasional wheel change, then it wouldn't be worth it. Many people here do there own maintenance, that's why it's mentioned. I maintain 5 vehicles at my house, so for me it was more than worth it

I jack up the rear until I can get a jack stand under the front. Then jack up the front from the center jack point put a second jack stand on the other side front, then jack up the back from the center jack point and put jack stands on the rear jack points. I'm real close to pulling the trigger on the quick jack.

I've fought with floor jacks/jack stands/shuffle routine for over 4 decades. Sure it works, it's pretty safe if done properly, but just time consuming and just kinda a pain in the ass, especially if you want to go up pretty high, then you need to go up in stages.
The quickjacks are just that, quick, all the hydraulic hoses use quick connects like an air hose, without loosing any fluid. Within a few minutes, you can set them up and have the vehicle in the air and locked and another few minutes to put the vehicle down and disconnect everything. With 5 vehicles to maintain, they save me a ton of time and I no longer despise jacking up my vehicles. I hang them on the wall mostly out of the way taking up little space. |

In the rare occasion you wanted to use the truck adapters, you could first lift with the rubber blocks, then use normal jack stands under the suspension points, set the vehicle on them, lower the quickjacks, put the truck adapters on, then lift again. So far, I haven't had the need to do that, though if doing a clutch, the additional height with the truck adapters would come in handy. To use the taller rubber blocks, on a lower vehicle, I use 4 short ramps I made from scrap 2x12s (stacked 2 high, laid flat) for all 4 tires. That gives me an extra 3" before placing the quickjacks. I also use the ramps for oil changes without using the quickjacks since they're quicker, 3 inches is enough to get to the drain plug and get a drain pan underneath. Work safe, work smart |

OP originally asked about the "properly" (safe) way to swap wheels and tires which evolved into a long discussion about QuickJacks and ramps.
Obviously, the safest way is to put the car up on four jacks or use QuickJacks (or any other kind of lift). I have QuickJacks and can't recommend them highly enough. I also have ramps but they are pretty much useless for the purpose of swapping wheels. Good for oil changes though! However, to just swap wheels and tires, here's how my wife and I do it at the track with our M4 and M3. Since you are not going to be under the car, you don't have as much of a risk if the jack fails. However, you can use one of the wheels you are removing as a safeguard.
IMHO, this is the fastest and most convenient way to swap wheels and tires with a minimum of risk. We've been doing it this way at the track for 10 years. I use the QuickJack to swap brake pads at home before and after track sessions. I can get the car up in the air, swap the pads on all four brakes, and let the car down in about an hour if I hurry, 1.5 hours if I take my time.

Pungo (and others) - I would store my quickjacks away like your photo. I am not convinced it wouldn't take 10-15 minutes from everything stored away/disconnected to car up and ready to rock. It takes me about 20 to do it with floor jacks and stands. So this is why I haven't bothered with Quick Jacks. If it's truly 5 minutes, or FOR SURE less than 10, I could be convinced, but I can see it being 15 or so to get them in position, line up with the jack points, connect everything up, raise to touch, re-check contact points, adjust and try again, etc. Any additional insight would be appreciated!
