Expert Buying Guide for 2019 Ram 1500 Quad Cab
For your 2019 Ram 1500 Quad Cab, the 77.8mm center bore is critical: aftermarket wheels often have a larger bore, requiring hub-centric rings to prevent vibration and ensure proper load transfer. The offset is sensitive—stick to the 19mm range to avoid rubbing or suspension interference. Always verify lug nut thread pitch (14x1.5) and seat type (cone or ball); using incorrect nuts can cause wheel loosening. Wheels from 2019–2024 Ram 1500 Quad Cabs are direct fit, but avoid 2018 models (5x139.7).
