7 years ago when I finished putting my car together I put a set of BF Goodrich Radial TAs on the car, I kept these on the car until last year when I replaced them with another set of TAs, during the time I had the original set on the car the white lettering on the tires remained white and looking great.
Since I have put the new set on the car I have had issues with the white letters turning yellow, I have not changed anything besides the tires, car is garaged and covered, washed/waxed and detailed regularly but the white lettering on the tires yellows after a few weeks.
Has anyone else had this issue?
Same problem. I think someone on this forum stated that the issue is the newer tires have white letters on a black sidewall, whereas older tires had a white sidewall with the non-lettered areas covered with a thin layer of black rubber.
It’s a bigger problem than you know. The early car owners who use all white rubber tires have the same problem with new all white tires. The tires turn brown or orange or gray in a year or less. The vendors thought it might be something with the tubes but then tires with the recommended tube inside turned colors too.
I don’t know the answer other than tires that used to be made in the USA are now being made overseas and the results are not too impressive.
Same problem here. I bought a new set of BFG TA’s this summer, and I’ve had to bleach-white and scrub them multiple times. Seems like they just turn brown while sitting in the garage.
A google search of why do my tires turn brown will give you the anwser.
Where are they made now.
I have 3 sets of T/A’s in 4 sizes. The newest are a set of 4 215/60-15s on my 71. They don’t turn Yellow as fast as the others. The set on Ginger are fronts 2235/60-15s and rear 255/60-15’ The 235s turn Yellow faster the 255s. The last set that are still on the Convertible I sold, but should be back by Spring are the same on the fronts, have always been a pain and one it looks like the Black didn’t get all cut off and always has had dark areas. The rears turn Yellow fairly fast.
I have a set of Cooper Discovers on my pickup, They don’t turn yellow hardly at all. It is usually just a gray dirty color that comes off easily. I rarely use a tire dressing on them though.
I kind of thought the Yellowing had to do with the Tire dressing I use and road dirt. But I have changed brands and need a new supply at the moment.
Info FWIW.
I read about this and so decided to go with Cooper Cobra Radial T/A’s. They have been on for several months and no problems yet - other than a shimmy that turned out to be two bent styled steel wheels.
I had that issue with T/As 20+ years ago, it turned out to be regular use of detailing products like armoural dressing.
A stiff bristle brush bought it back to white again.
I use Mother’s Back to Black Tire Renew. It removes the old tire dressing that browns the white letters.
I’ll spray the entire tire first to clean it then with a cotton cloth with some sprayed on it I wipe the white letters separately and they turn their original white. This product is so easy to use. No scrubbing required. Just spray and wipe. I now avoid tire dressings entirely and just use this to occasionally clean my Radial T/A’s.
