I think most of the stuff is fine where it is, the main thing I'd do is shorten the workbench a bit down to 5 or 6ft. and then build shelves. the main problem that I had with a large workbench was id work in a small section of it, and the rest would be junk. The best way to gain space would be to install metal or wood shelving units, and stack stuff vertically. So for tires, build a tire rack that is held on by the wall (if youre allowed to drill into walls and such). Keep all of your welding stuff in one area, and spare parts in another. I found using the black 27gal storage bins from Lowes/HD work well. Also, label/organize stuff. Much easier to have dedicated bins or spots than throwing everything everywhere. And last but not least, try to clean up after every project. Finished replacing a headgasket and have tools laying around? clean/put all your tools back into your respective spot, then move on to the next project. A clean and organized shop is an efficient shop. best of luck 👍
