The 1978 Cadillac Eldorado Base, Biarritz, and Cabriolet models roll on a 5x120.65 bolt pattern with 15x6 stock wheels. ThreePiece.us carries premium fitment options from trusted brands like American Racing, US Mag 1PC, and Performance Replicas, all verified to bolt directly onto your Eldorado without modification.

Upgrade possibilities range from 15-inch to 17-inch diameters across multiple widths, giving you flexibility to match your style. Every wheel ships free to the lower 48 states, and our specialists ensure perfect fitment before your order leaves our facility.

1978 Cadillac Eldorado Wheel Fitment Guide — What Works & What to Avoid

Your 1978 Cadillac Eldorado rolls on a 5x120.65 bolt pattern with 15x6 wheels at a 38mm offset from the factory. You can step up to 15x6.5, 15x7, 15x7.5, or 15x8 while staying with fifteen-inch diameter, or move to 16 or 17-inch options in compatible widths. Since your Eldorado isn't staggered, front and rear fitment remains consistent across all square setups.

Keep in mind that only the 5x120.65 bolt pattern will secure to your hubs. Your 70.3mm center bore requires hub-centric rings on any wheel with a larger bore—this prevents vibration and keeps everything centered. Avoid excessive width or aggressive offsets that push the wheel face too far outward, as the Eldorado's suspension and fenders have limits you'll want to respect.

Every wheel we list for your Eldorado bolts on and ships free to the lower 48 states. American Racing, Vision, Ridler, and US Mag 1PC are just some of the quality brands we stock that fit your classic Cadillac perfectly.
