Just a quick one here: My tires seem to be getting a brown band mid-sidewall; looks almost like it's getting dry. They're fairly new and I don't think there's any cracking, but I've never seen this before.
Thoughts? I don't want to take it to a tire place and be told I need tires (like they tend to say) unless that's truly the case.
The brown color is caused by anti-oxidants and anti-ozonants put in the tire to keep them from cracking. They are designed to come to the surface of the sidewall and protect the rubber from O2 and O3. Based on different conditions, this becomes more noticeable in some conditions / tires than others. Go ahead and wash off with soap and water first before trying the tire cleaners.
