1968 Plymouth GTX Base Wheel Fitment Guide — What Works & What to Avoid
The 1968 Plymouth GTX Base runs a 4x114.3 bolt pattern with a 66.1mm hub-centric bore. Your stock setup is a 14x4.5 wheel at a 12mm offset. You can upgrade to wider 14-inch options up through 14x7, or step up to 15-inch wheels in 15x6.5 or 15x7 fitments. Since this car isn't staggered, you're free to use matching sizes front and rear for a cohesive look.
The 4x114.3 bolt pattern is the only pattern that fits this classic—there's no flexibility there. Make sure any wheel you choose has a center bore of 66.1mm, or use hub-centric rings if the bore runs larger. Avoid wheels with offsets significantly more aggressive than stock, as the narrow chassis and suspension geometry on this era of muscle car can lead to rubbing against the fenders or suspension components.
Every wheel listed here is confirmed to fit your GTX Base and ships free to the lower 48 states. We keep Work Wheels, Enkei, SSR Wheels, and Rotiform in stock, all ready to bolt straight on.
