Replacing Skins on seats- Hog Rings & Pliers- Coupla questions

[CMG]

I got the OEM hog rings from BMW so I should have what I need to do it. Is there a process to getting it on nice and tight? Like do I put on just the corners then work in a x pattern back and forth. I've never used hog rings before so don't know if they are squeezed into one size or if you have to squeeze them to just the appropriate tension

Thanks that's what I was looking for. Got some matching front seats now so time to put on the rear covers and slap em in.

There are different sizes. You want 3/4" automotive grade hog rings.

I've used rings from ace

I've used rings (auto grade -?) that came with my $20 pliers and also used bronze colored hog rings picked up at Ace Hardware with the same pliers. Both worked well.

It's not complicated. I used these hog rings and these pliers.

One pack of hog rings did my entire interior but get two packs just to be safe.

You will figure out which method works for you. Just use your head and think about what will be most secure. That's it.

So if i understand, the hog rings are generic size and it depends how tight you clamp them that determines the size?

Eastwood sells both straight and angled hog ring pliers. They come with about 100 hog rings. $20ish I believe. I bought the straight one to recover one of my front seats.

I did plenty of seats when I worked at Land Rover.

The hog rings are generic.

There really isn't a lot of technique. Just line up the wire embedded in the foam with the wire or hole in the upholstery and clamp the hog ring around them both, clamping them together.

Cutting out all of the old hog rings is the hardest part of the job.

Specifically for redoing the back seat on an e30 m3. but in general I had some questions about the hog ring part. I already know the kinds of hog ring pliers I need. I don't know if they are adjustable or whether you need to get size specific supplies. Just need some specific info on that part of the process.

-Do I need to get a specific size or gauge hog ring to match oem bmw? If so, what size?
-If hog rings are not size specific and they are varied in size is there a special technique to getting it right?
