Sadly, Linda passed away in 2025, we learned.  I'd be happy to provide advice on your project, as I am just in the process of resecuring my bath/shower after removing it for a complete interior remodel.  Share what you're up to, goals, your capability, etc and there are others here who can also help.

linda come back, i'm about to take out my bathroom/shower and need you to stop me!!!

I just thought the tire size was a typo, after your comment I looked closer. Do you know how many tires pop up on Google when you search 215/60/15.5.
