DOT drag radial for GNX wheel

[hottrawd]

Maybe someone over here can help me out with this.
Any suggestions for a good drag radial that fit the 16 inch gnx wheel without rolling my fender?

The biggest I found was a 255/50. I wish I could find a 275/50.

M&H makes a 275/55/16 drag radial.I'm not sure what backspacing the wheels would need to fit these.
My 255-50-16 M/Ts on GTA front wheels are real close to the frame rails.
