You could use a simple client-side JS OCR library, like GOCR.js[0]. It may only work on good photos of relatively new tires with clearly printed text, and that's not always what bicycle tires look like when you're looking to replace it, so not sure how useful it'd be.

I tried to to use GOCR packaged with Ubuntu on playlists, expecting it to work well since it's computer output. But it turned out not working so well. I also tried scaling the text but that didn't fix it.

Interesting approach, thank you. Sure, old tires might be hard to scan, but definitely worth to think about.
