Tire Browning

[dubbadog]

I have just started using Mequires Endurance on my tire's last year and just lately have noticed some parts of the tire turning brown. I did'nt think that this product did that. Any suggestions for other product's I could try that did not have this browning effect would be appreciated. ( I prefer a wipe on ,not a spray )

It is not Endurance causing that, it is the tires. Do a search on the web for tires and blooming. The sidewalls are designed to do that when they heat up. The brown stuff is anti-oxidizing chemicals that protect the sidewalls from UV. Some tires do it more than others. What usually agrivates the browning is using a harsh chemical to clean the tires with.

There is a good post on blooming by Mike Phillips at the link below.

I don't think it was from the tire dressing. Did you let it set before driving?

I have never used the Endurance dressing. Is it hi-gloss? Because they will usually attract more dirt.

The browning effect is from dirt getting into the pores of the tire. A high alkaline cleaner will do the trick. I use dilluted simple green, some others are APC from meguiar's, or Eimann Fabrik Hi-Intensity cleaner.

While speaking to engineers from Michelin, Goodyear, Bridgestone and a few chemical companies that manufacture dressings and cleaners for popular consumer/pro lines, most told me that tire browning occurs for one of a few reasons:

1) The silicone reacts with moisture and turns brown
2) The additives in the tire migrate to the surface of the sidewall and react with moisture and turn brown

They indicated that in very humid climates, it's not uncommon for a dressing to brown just from the humidity in the air... I thought that was pretty interesting.

The amount of "gloss in a dressing" usually has little to do with dirt attraction - I've seen some really matte products attract their fair share of dirt/dust. But, as we all know, everyone's results may (and usually do) vary.

rj is 100% accurate about the cleaner exaggerating the browning effect - some strong cleaners can force the tire additives to the surface, and the reaction is evidenced by the brown foam that forms on the tires when wet.
