I am surprised that someone hasn't come up with a sealant for the white letters so the dirt just rinses off.
In theory, there is no difference between theory and practice. In practice, there is.

Seems to me it's related to heat in the tires: the lettering on my slicks would be browner nearer the "tread" than it was near the rims. I'd wipe off the "Goodyear" lettering with lacquer thinner - hey, I'd advertise for them if they were free... ![laugh2 laugh2](/ubbthreads/images/graemlins/custom/laugh2.gif) In any case, I'm not much of a white-letter guy anyway; I think cars look visually cleaner/less "busy", so to speak, without lettered tires. But for something like a '70 F60 restored car, you're kind of stuck with the letters.

Know why they do it https://autofella.com/how-to-clean-car-tires/
The main culprit is an organic compound that goes by the name of anti-ozonant. Anti-ozonant is added to rubber and plastic materials to prevent oxidation, fading, cracking, and premature degradation.
Anti-ozonant is constantly drawn to the surface to constantly protect the material from oxidation caused by repeated and constant exposure to UV damage, high temperatures, dirt, and mud.
You can think of it this way: anti-ozonant is like applying sunscreen lotion on your skin when you’re out all day on the beach. Without sunscreen, you will burn to a crisp in less than 2 hours.
Anti-ozonant will serve to protect and prolong the life of the tire. Without it, you will need to constantly buy new tires as UV damage and heat will significantly shorten the lifespan of the rubber compounds in your tire.
But there’s a catch. When the anti-ozonant is exposed to air and moisture as it is drawn to the surface of the tire, it oxidizes and leaves a brownish residue. This is the main cause of tire blooming.
Tire blooming can also be partly blamed for lubricant-type chemicals that are applied in the manufacturing process, particularly in the inside of the tire mold. Think of it as a non-stick coating that allows the tires to release smoothly from the tire mold.
This non-stick coating will chemically bond with the tire in such a way that it holds a lot of anti-ozonant on the surface of the tire. You know what that means, right? As more of the anti-ozonant is drawn to the surface of the tire, then more of it will oxidize and cause those ugly brown stains on the tire sidewall.

this reminds me of the time in the early 70's when i bought all the wide white wall tires from the local tire shop. these were tires they had for many years and couldn't sell. by then, most of the blue stuff that was supposed to protect the white wall until mounted and washed off had disappeared from moving around over the years. although somewhat dirty, the white was, well, still white. after a little cleaning, these things looked great. since this was way before the interwebs, i advertised them in hemmings, and made a good buck, selling all of them pretty quickly. ![beer beer](/ubbthreads/images/graemlins/custom/beer.gif)

I started using Bleechy White in the early 60's, when it had Sodium Metasilicate in it as the active ingredient. That stuff would take your breath away, but it sure got whitewalls white. Todays product is a mere shadow of what it used to be.

As far as today's white letter tires turning brown & crappy rubber compounds, I put a set of OWL Firestones (NOT the vintage tires, but current SUV tires) on my wife's Grand Cherokee, & a year later the OWL's are still nice bright white letters. So not all of today's rubber compounds are created equal!
