I have Good Year on my Rallye wheels on my Charger to simulate the old Good Year polyglass look. They also brown like BFG's over time. I have Coopers on my Cragar wheels with the RWL inward, my Roached Runner with RWL inward, also have Coopers on my New Yorker with the grandpa white walls out and they have not browned at all over the years. Old school from the 80's BFG's still on project Charger #2 and they never brown.
