What is the bolt pattern on a 1998 Chevy Cavalier?
The 1998 Chevrolet Cavalier uses a 4x100 bolt pattern: four lug holes on a 100 mm circle.
This article explains what that means for wheel fitment, how to verify the bolt pattern on your car, and practical tips for buying replacement wheels or adapters.
Bolt pattern specifics
Understanding the 4x100 bolt pattern helps you determine which wheels will fit and what adapters may be needed.
Key details include the lug count, the bolt circle diameter in millimeters, and typical seat types used by the wheel nuts.
- Number of lug holes: 4
- Bolt circle diameter: 100 mm (often described as 4x100)
- Common lug nut seat type: 60-degree conical seat
- Center bore: typically requires a hub-centric fit for proper centering (verify your vehicle’s hub bore before purchasing wheels)
When shopping for wheels, matching the 4x100 pattern is the primary requirement; other factors like center bore and offset influence fit and handling.
Compatibility and common considerations
While many wheels from GM compact cars share the 4x100 pattern, not all will fit without adjustments. The Cavalier's suspension and brake components may affect wheel clearance.
- Wheels from other models with 4x100 bolt pattern may fit, but verify center bore, offset, and brake clearance.
- Aftermarket adapters exist, but they can change offset and handling; use caution and professional installation if needed.
- Offset and backspacing impact fitment; typical offset for Cavaliers varies by wheel design, so check spec sheets.
Always confirm the exact specs for your trim and wheel choice before purchasing to avoid clearance or alignment issues.
How to verify bolt pattern on your Cavalier
There are several practical ways to confirm the bolt pattern if you’re unsure.
- Check the vehicle’s door jamb sticker or the owner's manual for wheel specifications (look for 4x100 or 100 mm).
- Measure the bolt circle diameter: with a ruler or calipers, measure across the wheel from the center of one lug hole to the center of the opposite lug hole. For a 4-lug pattern, this should be 100 mm (about 3.94 inches).
- Ask a professional or refer to a trusted parts catalog for your exact year and trim to ensure compatibility.
Accurate verification helps prevent the purchase of wheels that won’t fit or will require modification.
Summary
In short, the 1998 Chevy Cavalier uses a 4x100 bolt pattern. When replacing wheels, ensure the pattern matches, and pay attention to center bore and offset to achieve proper fit, clearance, and alignment. If in doubt, consult a wheel specialist or your dealer.
