Bfg tires letters turn brown

-
There use to be a product for whitewalls from Westleys, looks like it is now owned by Black Magic. It was mentioned above. That's what I use on white letters. If your car sits outside in the sun, let me suggest some wheel covers, like they use on RVs and trailers.

Mine will discolor in the garage over a week's time.
 
Yeah if there is a defect guess nothing will get them white. I just bought two BF's for my car. Not mounted yet, think I'm going to sell them and go with Cobra's. I've used them before and found them to be a good tire for as little miles that I put on. I like the old school look white letters with steelies, selling my slots.
 
For those using products like Westley's Bleche White, I found out the hard way that it can remove rallye wheel paint.

I still use it on my white wall tires, but I spray it on a rag & use it to scrub instead spraying the whole tire now.
 
Like many of us motor heads have over the years accumulated a vast assortment of “snake oils”, only to find the product short in its promises. If the product is costly or caustic it is not sold to the general public for our use. So really we get a watered down version to do our bidding with usually not so good results. If Domino's can have over 150,000 nation wide Hot Spots way can't they make a decent white wheel cleaner.
No all sidewalls/ lettering are created equal, certain tire manufacturers uses a releasing agent on their tire molds, like butter on a hot frying pan. That agent they use lifts up from the white causing to eventually turn a shade of brown..much like burnt butter......not all the cleaning will help this problem and recurrence will be for sure.
One of the reason why I don't do white, I like white, can't see spending more time on the white walls cleaning then the car. But the bike I own has them, and making them bright white is a priority in my daily misadventures. So after a cascade of chemicals, brushes, pads, and snake oils I tried and as horrific as it may sound...a low cut polishing compound. What I use is from ZEP Aviation #F38001, and I am sure there are other compounds that will work.
Try a small area first using PAPER towels and if works for ya, great......

Yep, I've bought about that many products and none have worked. :BangHead::BangHead::BangHead:
 
the only thing that seemed to get the brown off my white letters was a random orbit sander with a 120grit disk. Cleans them up pretty good, but they still turn brown again after a while.

Any opinoins on red line tires on ss crager on a 71 duster.

1971 is too new for redlines IMO, the last year for factory-offered redlines was 1970 and even by then they were out of style. Of course, that was then and this is now. It's your car, do what you like. :thumbsup:
 
Thanks for your opinoin sir. I was kinda think,n the same thing.i probably keep cleaning my white letters keeps me out of trouble
 
I would buy a better quality set of tires like Cooper or Mastercraft Avenger G/T’s..., last time I checked they were still made in the USA too. I used to work for a tire company for 15 years and never was impressed by BFG, most people just pay for the brand name.
 
I bought a set of 4 BFG's at the same time.

The two 215/70/14's have bright white raised letters that hardly ever need cleaning and never have gone brown.

The two 245/60/14's have letters that within two weeks go dark brown. It's really weird.

I've tried just about every product out there and have found that simple brake cleaner on a rag works best to get the brown off and is the cheapest method.

Thanks, I'll have to try that.
 
This thread made me go back to my chemistry roots and figure out WHY the white letters are turning brown.

It turns out that the reason why is because of an antiozonant compound that they put in the rubber to protect it called N-Isopropyl-N′-phenyl-1,4-phenylenediamine known as IPPD.

IPPD reacts with ozone faster that the rubber does and therefore protects the rubber. However, IPPD also turns brown when it oxidizes.

The comments about brake cleaner working made me go look at the solubility of IPPD. It is practically insoluble in water and slightly reactive with chlorine. However, it it highly soluble in Acetone.

To confirm the hypothesis that the IPPD oxidized residue is the culprit, I took some acetone and an old tooth brush and scrubbed the “A” on my T/A tires for 15 secs and then wiped it off.

Hypothesis confirmed.

This explains why brake cleaner seems to work also since it contains solvents similar to acetone.

Now everyone should easily be able to clean their white letters with just some acetone and mild scrubbing. I know I will!

Years ago always used carb cleaner and tooth brush.
But each time your removing white pigment
