Opinions wanted: '75 Duster with 18" Boss 338 wheels 4.5"backspace

The car is a 340 four speed Duster with an A body 8 3/4 pushing 3.91 gears. Pump gas motor. Front and rear heavy bumpers have been replaced with fiberglass. Weld-in frame connectors.
All, looking to purchase 18" X 8" wide Boss 338 5 black spoke, chrome lip wheels (old school type) for the Duster. Rolled the rear fender lips in. Same size tire front and rear. Looking to go with maybe a 225 26" tall tire. Front end has 1.03" torsion bars, poly bushings, F & R. Anyone done this with this size wheel/tire combo? Any clearance issues?
Tire brand selections? This car will only be driven 2000 miles/year. Want sticky tires, not 60,000 mile ones. I want to purchase and install, with no worries about turning, rubbing etc.
Thank You in advance
