First mopar

Congrats and welcome! Got my Dart 10 months ago after 42 years without a Mopar. My 3.55 8 1/4 SG rear provides great launch, but highway travel is kinda revvy. What size rear tires are those? There's a lot of good advice on this site. Rest assured, you landed on the best site and you landed a great car! Again, Welcome to FABO!
