I'm old school & one of the first things I did to my '06 GT was to add white letters to the tires. Used a Paint pen from Autozone. Didn't last long & had to re do every few weeks. Took off after a while. Attached a pic showing the white lettered tires.
Current tire manufactures generally only offer white letter tires for trucks. Not so much for cars anymore.
Lol, I remember doing the exact same thing. My 2011 V6 came with 17" B.F.Goodrich Radial T/A Spec tires in P225/60 R17. Dealer/Ford mounted them with white letters on the inside. Noticed this while changing my oil.
