What happened?

I was washing my truck earlier and when everything was said and done, I moved to the tires. I did my usual routine of rinsing, spraying and rinsing again and when the tires dried, they had a weird color or ring around them. I do not scrub the tires rough or anything and no cleaner seems to remove it. Does anyone know or have a good guess as to what happened to the tires?

I used Bleach-White tire cleaner for the tires and once, a long time ago, I used Meguiars Endurance tire wet. If I remember correctly, I noticed a slight discoloration a while ago after driving through a rain storm but it wasn't too bad. The tire wet seemed to have a weird behavior around the part though and voila, look what happened now months later. I have used both these products hundreds of times before on numerous vehicles and tires and never had a problem. Is that little ring around the lettering dried out somehow? Is there anything I can do to remedy it? Thank you so much for any help given. I wasn't sure what to search for this.

From everything I've heard the way they get the white lettering is to add up layers of white rubber on sideways then a final layer of black to cover up the areas where white is not wanted (the area around the letters). My best guess would be to say that the tires are starting to show age and the black layers is wearing thin allowing the white layers to peak through. As you can see the areas where the black would have been the thinnest (area shadowing the letters) is more of a white color than the whole sidewall which also looks like it is a light grey color. With more time that layer of black will keep disappearing and show off a great white wall tire.

Interesting. The only thing is that the tires are only 4 months old so dont know about age being a factor. I will say that I went back out to clean them one more time this time leaving the cleaner on for a oittle bit longer and that seemed to do the trick. Theres still a slight ring there but nobody would notice it. I guess I ran over some really nasty stuff and it just built up. I dont know if I believe that fully myself but thats all I have to work off of. I do appreciate the reply though. I never knew that about white lettering on tires.

Yeah we'll see how this goes in the future. Like I said, something still doesnt seem right but itll do. My tires dont stay clean for very long anyways Pretty embarassing problem if you ask me but thats how it goes sometimes.
