Thanks everyone who answered my question about the yellowing/browning of the white lettering on BF Goodrich TA Radials. I checked out some of the other threads on this and seems there IS an issue with these tires . I picked up a quart of acetone from Home Depot about $7 and a half bucks . THIS REALLY cleaned them up big time ! The white lettering looks new ! I used a cotton cloth soaked with acetone and rubbed vigorously took just seconds . Be sure to use gloves with this . This is an awesome site. Thanks .
