Default Coker Bias redline color fade

I am sure this has happened before. I have a set of Coker Reline bias tires on my 64 GTO and redlines are now pink and couple are white. I have seen this before.
I was told by Coker tire tech that I need to clean it with simple green and drive the car for about 100 or so miles and redline color will come back. I couldn't believe what I was hearing. I did what I was told and obviously that didn't fix it. These tire are about 2 years old. Has anyone experience this and did Coker Tires warranty it.
Thank you

They should warranty that. But as I have always said, Coker tires are great for driving on and off of a trailer. I have never been a fan.

I agree Sir
I bought it for period correct reasons. I don't like the way the car drives. I did what they asked me to do and I am calling them next week and demand on credit my my purchase towards on maybe getting BFG radials. Originally I had BFGs on it and raised white letters were on the inside. As the tech stated that driving the car the red will reappear magically was not a good solution
Thank you

Let us know the outcome please. It could help others deciding whether to go with Coker or not.

Maybe if you drove it 100 miles in reverse the stripes would turn green??

Sounds like they used red dye instead of red rubber to achieve the red. Now the red dye is fading and going away and you will soon have whitewalls..

I laughed when he told me I need to drive it to get the color back, but he was serious. I've a mechanic since 1977 and couldn't believe what I was hearing. I am going to call Coker Tire this week and send him new photos. I will post the outcome
Thank you

100% agree with you there. The set of reproduction Firestones I put on my Chevelle were not even all the same diameter, difference from one tire to another was almost an inch in diameter. Played hell with my posi when I had those two different sizes on either side of the rear. Coker did nothing to help me with the issues. My only solution to get some use out of the tires was to find two that were the closest in diameter and put those two on the rear.

These issues are why I bought Diamond Back tires for my several muscle cars. Red lines and WSW. Never had a problem and you get a modern tire that's on thousands if not millions of cars.

By the way, BFG has had a "browning" problem with their white letters. The Corvette site posted the BFG customer satisfaction bulletin. Customers will need to wet sand the white to get the brown out. I tried it. It works but needs to be repeated from time to time, like several times during the summer. Not a big deal when you are washing the car.

What steered me away from Diamond Back is that they are a "remolded" tire. Remolded tires can run hotter... and they don't look right.. I would be worried about the remolded part delaminating. I have never had a set... I dunno...

I have not had this problem with Diamondback redline radials. Even after 20 years, the red color was still vibrant on 2 sets. Those are long gone. One set lost chunks on the inner sidewall. The other went on a car that is only driven very seldomly for short distances (not me, different owner)
i'm now on my 4th 5th and 6th set of diamondbacks. The beauty of it, is that you can choose your favorite tire, or just use the one they have in stock.

Never heard the term "remolded" in reference to Diamond Backs. But I have had many sets over the years. Never overheated, never turned pink or whitewalls brown. That's my experience.

Sounds like a job for the paint Fairy to come and take care of, ever tried to get paint off a tire that got on by mistake..

This is disheartening though since they (Coker) are about the only game in town aren’t they?

Count me as another Diamondback fan. Have had multiple sets of redlines and wide whitewalls from them with excellent luck.

I don't need to buy redlines anymore as I went to 17's and still run my poverty caps on black 17" Wheel Vintique rims with the redline painted on....

I have Diamonbacks on my two '64 GTO's. They are BF Goodrich radial redlines.

The ride & handllng is top notch, so much better than bias ply originals. The redlines on one set are bright red as they were when new--10 years ago. The redlines on the other set have gotten dull. I have not found a solution to restoring the brighter red.

I've tried SOS pads, Mop n' Glo, and other suggestions I've heard.

ANy ideas on a solution?

Default Sharpie

Way back in the day, 1980’s we would use a 3/8’’ Red Sharpie and just go around the Red line one time and the fade was gone.
