Been running BFG T/As for decades and never had the white letters change colors. On the upside, killer wet traction for about the first 10,000 miles. On the downside, never got more than about 45,000 miles on a set.

Because of that last issue I decided to try a couple sets of Dunlop GT Qualifiers. Very similar tread pattern, advertised as 60,000 mile tread life, a few bucks cheaper and many reviews say they're just as good as the BFGs. My experience, with two different cars, is that they straight up suck in the rain.
