White letter problem with bf goodrich tires

The white lettering on my new bf goodrich ta tires are dull on my back tires and the front are white except on the outer edges they are dark and will not come off.The bf goodrich rep at the good guys show said the oils in the rubber was bleeding through and to let the dealer i bought them from know.I did and i do not think they are going to do anything.Any one have this problem and what did you do
