Contact Mike Maier inc.
Mike was running I believe 18x9 or 18x10 square with a 265 quite sometime ago on old blue when it had torque thrust M wheels. with that size tire be prepared to modify the wheel lips at the very least.
after looking at it again it may have also had his small flare front fenders.

Mike is easy to talk to and he is willing to share.
