None currently in the gym but I've found my new local source. Unfortunately I am limited on space and the biggest downside of tires is how much space they take up, especially when you are trying to find the right weight. Upside is they are free.

Use this one at the gym when I have no other options. It does it's basic job. If it's the only one available I throw on straps for deadlifts since it has almost no grip.

I used these as a tool for "dorm room" training on several work trips when I didn't have time or transportation to easily make it to a gym. Now I still use some of the bands for stretching and warming up. Biggest issue is if someone isn't paying attention to how they have the bands set it they could rub on sharp edges causing damage.

Very basic but durable rack set up. I'm personally not a fan of the way the barbell holders are set up, being 4 pegs. I also believe these safeties wouldn't hold up to much dropped weight or too many heavy rack pulls.

Enjoy using these at a local gym. They've been around a while and stand up to use, but I can't specify on price/ accuracy.

My custom DIY version of a plyobox has been laying a tractor tire on its side. This has been handy for power stairs training. Great value being free, but takes up a lot of space and not a lot of height options.

They get the job done as bumper plates. The lighter ones could be a little thinner, but they've held up to being used a lot.

Used this a lot on one of the bench set ups I had that included a leg extension/leg curl to be able to load it up with Olympic plates
