What is the bolt pattern on a 99 Chevy?
The most common bolt pattern for 1999 Chevrolet vehicles is 5 lug on a 4.75-inch circle (5x120.65 mm). Heavier GM trucks and larger SUVs from that year typically use 6 lug on a 5.5-inch circle (6x139.7 mm).
Bolt pattern varies by model and body style, so it’s essential to verify for your exact vehicle. This guide outlines the typical patterns seen in 1999 Chevrolets and how to confirm yours before buying wheels.
Common bolt patterns for 1999 Chevrolet lineup
The following patterns cover the most common 1999 Chevrolet models. If your model isn’t listed, consult the owner's manual, the factory window sticker, or a wheel database to confirm.
- 5x120.65 mm (5 on 4.75 inches) bolt pattern — used on most passenger cars and many mid-size trucks (examples: Cavalier, Malibu, Camaro, Corvette, S-10).
- 6x139.7 mm (6 on 5.5 inches) bolt pattern — used on full-size GM trucks and large SUVs (examples: Silverado 1500, Suburban, Tahoe).
These patterns cover the bulk of 1999 Chevrolet lineups. Always verify with the exact model and trim, since there can be exceptions for rare specialty vans or commercial models.
Notes on model-specific patterns
Extra context: The 5x120.65 pattern matches many classic Chevy cars and performance models, while the 6x139.7 pattern is standard for the GM truck family’s heavier configurations. Some 1999 vans or special editions may differ, so check the exact spec plate or VIN-based databases for precision.
In short, if you’re shopping for wheels for a 1999 Chevy, start by checking whether your vehicle is a passenger car/mid-size SUV (likely 5x120.65) or a full-size truck/SUV (likely 6x139.7) and verify against the official spec for your exact model.
How to verify the exact bolt pattern for your vehicle
To ensure you buy wheels that fit, confirm the exact bolt pattern for your specific vehicle instead of guessing from the model year alone.
- Check the owner’s manual or the driver-side door jamb placard for wheel specs. Look for "Bolt pattern" or "Lug pattern" details (for example, 5-120.65).
- Count the number of lug holes on your wheel: 5 lugs typically indicate a 5-lug pattern, and 6 lugs indicate a 6-lug pattern.
- Measure the bolt circle diameter. For a 5-lug setup, measure between the centers of opposite lug holes (roughly 120.65 mm for the common Chevy pattern). For a 6-lug setup, measure across the circle (approximately 139.7 mm).
- Use a bolt-pattern gauge tool or an online lookup database to cross-check your measurements against model-year combinations.
- Confirm center bore size and hub compatibility as well, since these affect fit and centering even if the bolt pattern matches.
Once you’ve confirmed, you’ll know which wheels will fit and what offsets or bore sizes you may need to consider.
Summary
In 1999, Chevrolet commonly used two bolt patterns depending on the vehicle class: 5x120.65 mm for most cars and many mid-size trucks, and 6x139.7 mm for full-size trucks and large SUVs. Always verify the exact pattern for your specific model using the owner’s manual, door placard, or trusted wheel databases, and consider related factors like center bore and offset when selecting wheels.
