Will 1990 Dodge 4WD Wheels Fit a 1990 Geo Tracker? The Definitive Answer
The short answer is: probably not, and it's crucial to understand why. While both vehicles were manufactured around the same time, their wheel specifications are likely significantly different, making direct interchangeability unlikely. Let's delve into the specifics to understand what determines wheel compatibility and why a simple "yes" or "no" isn't sufficient.
What Determines Wheel Compatibility?
Several factors influence whether wheels from one vehicle will fit another:
-
Bolt Pattern (PCD): This refers to the number of lug nuts and the diameter of the circle they form. A mismatch here is a major incompatibility; the wheels simply won't bolt onto the hubs. 1990 Dodge trucks had numerous models with varying bolt patterns, whereas Geo Trackers generally have a specific pattern. You must know the exact bolt pattern for both your Geo Tracker and the Dodge 4WD wheels in question.
-
Wheel Offset: This measures the distance between the wheel's mounting surface and its centerline. Incorrect offset can cause rubbing against the suspension, brakes, or body, leading to damage or even accidents. Even if the bolt patterns match, an incorrect offset will prevent a proper fit.
-
Wheel Diameter and Width: While not a direct bolt-on issue, incompatible diameter and width can create clearance problems, causing rubbing against various components. A larger diameter might not clear the brakes or suspension, while an overly wide wheel may rub against the fenders or body.
-
Center Bore: This is the diameter of the hole in the center of the wheel that fits over the hub. An incorrect center bore will mean the wheel won't fit snugly onto the hub, leading to potential safety issues.
Why a Direct Swap is Highly Unlikely
Dodge trucks and Geo Trackers, even from the same year, are vastly different vehicles in terms of size, weight, and intended use. A full-size Dodge 4WD truck is significantly larger and heavier than the compact Geo Tracker. This difference directly impacts the design and specifications of their wheels. The Dodge wheels are likely designed for much heavier loads and will often have a different bolt pattern, offset, and center bore than a Geo Tracker.
How to Determine Compatibility
To determine if specific 1990 Dodge 4WD wheels will fit your 1990 Geo Tracker, you must find the following specifications for both the Dodge wheels and your Geo Tracker's hubs:
- Bolt Pattern (PCD): Example: 5x114.3 (five lug nuts on a circle with a 114.3mm diameter)
- Wheel Offset: Usually expressed as a positive or negative number in millimeters (e.g., +35mm, -5mm)
- Center Bore: Expressed in millimeters (e.g., 73mm)
- Wheel Diameter and Width: Example: 15x7 (15-inch diameter, 7-inch width)
You can typically find this information on the wheels themselves (often stamped), in the vehicle's owner's manual, or through online resources that specialize in automotive specifications. Comparing these specifications is the only reliable way to determine compatibility.
Alternatives to Using Dodge Wheels
If you're looking for new wheels for your Geo Tracker, focusing your search on wheels specifically designed for that model or similar compact SUVs will ensure a safe and proper fit. Many aftermarket wheel retailers allow you to filter your search by vehicle year and model, making the process considerably easier and safer.
In short, attempting to fit 1990 Dodge 4WD wheels onto a 1990 Geo Tracker without verifying the exact specifications is highly risky and strongly discouraged. Prioritizing safety and compatibility is crucial when selecting wheels for your vehicle.
