1981 Isuzu I-Mark Wheel Fitment Guide — What Works & What to Avoid
Your 1981 Isuzu I-Mark uses a 4x100 bolt pattern shared across Base and DLX trims. The stock wheel measures 13x5 with a 45mm offset. You can upgrade to larger sizes including 13x5.5, 13x6, 14x5.5, 14x6, 15x6.5, 15x7, 16x6.5, 16x7, or 17x7, all maintaining the same bolt pattern and allowing you to customize your look without special adapters.
The 4x100 bolt pattern is the only specification that fits your I-Mark; any wheel with a different bolt pattern will not mount. Your hub measures 56.6mm in diameter, so use hub-centric rings if your wheel's center bore exceeds that size to ensure proper centering. Aggressive offsets or very wide wheels risk contact with fenders and suspension components, so moderate fitment choices work best on this classic compact.
Every wheel we list for your I-Mark bolts on correctly and ships free throughout the lower 48 states. Vors, Heritage Wheel, Work Wheels, Motegi Racing, MST Wheels, Petrol, Enkei, and Shift all have sizes in stock ready to transform your ride.
