What bolt pattern is a 98 S10?
The 1998 Chevrolet S-10 uses a five-lug wheel pattern on a 4.75-inch bolt circle (5 on 4.75 inches, or 120.65 mm). This guide explains what that means and how to verify wheel fitment when shopping for replacement wheels or tires.
Understanding the bolt pattern
Bolts on a wheel are arranged in a circle around the hub. For the 1998 S-10, there are five lug studs evenly spaced around a circle with a diameter of 4.75 inches. This combination is common among GM compact trucks of that era, helping determine wheel compatibility across models.
Key specs for quick reference:
- Five-lug configuration (5 studs).
- Bolt circle diameter: 4.75 inches (approx. 120.65 mm).
- Hub bore and offset are additional considerations for proper fitment.
In practice, most wheels designed for GM's mid-to-late 1990s compact trucks will share this pattern, but always verify the hub bore size and offset to ensure a proper, safe fit.
Cross-model compatibility
Wheels from other GM models from the same era often share the 5x4.75 pattern, including the S-10 and Sonoma family. Always confirm the exact center bore size and offset for any wheel you plan to mount, and avoid using spacers unless recommended by the vehicle or wheel manufacturer.
How to verify the bolt pattern on your specific truck
To verify wheel compatibility for your 1998 S-10, follow these steps.
- Inspect your current wheels or your owner's manual to confirm the lug pattern (five lugs on a 4.75-inch circle).
- Measure the bolt circle if you are uncertain: measure from the center of one lug hole to the center of the opposite lug hole across the circle; it should be 4.75 inches.
- Check the wheel center bore size and whether the wheel is hub-centric or lug-centric to ensure secure mounting.
- Consider wheel offset and backspacing to ensure adequate clearance with brakes, suspension, and fenders.
- Consult a tire and wheel professional or use manufacturer fitment charts when buying aftermarket wheels or rims.
By following these checks, you can confidently select wheels that fit the 1998 S-10’s bolt pattern without modification.
Summary
The 1998 S-10 uses a 5x4.75-inch bolt pattern (five lugs on a 4.75" circle). When shopping for wheels, verify offset, center bore, and hub compatibility in addition to the bolt pattern to ensure a proper, safe fit.
