I originated this topic. After posting, I contacted Coker Tire again (where I bought the original set) and they again offered to replace them under a defect warranty. The first time, they also paid the cost to have them removed and remounted. This time they did not reimburse me for that. The third set cleaned up nicely and maintained good brightness for a period. I have noticed none of the browning of the first two sets. However, IMHO they do not clean up as bright as other RWL tires I have had over the years. I will keep this set and kudos to Coker for working to make this right.

FYI, I also put a set of Michelin RWL tires on my truck last year. They do not seem to clean up as bright as RWL tires from years past, either. I believe the manufacturing process has changed and the quality of the material used for the RWL is not of the same caliber. Just my thoughts.....
