The 18×9 +12 offset is a mild, inboard step from most stock 1500 applications, which typically run 17–18-inch wheels with higher positive offsets; this setup will sit slightly more flush without requiring suspension modification on stock ride height. A square 18-inch tire fitment (matching width front and rear) is practical and balanced, though verifying sidewall diameter against your specific trim's speedometer calibration is recommended. No fender rolling or spacers should be necessary, though final clearance depends on your truck's suspension condition and any prior modifications.
