What bolt pattern is Saturn?
Most Saturn vehicles use a five-lug wheel pattern, with 5x100 mm being the most common across many S-Series and early Ion models. However, bolt patterns vary by model and year, so you should verify your exact vehicle’s pattern before buying wheels or tires.
Understanding bolt patterns
A bolt pattern (also called lug pattern) describes how many lug holes a wheel has and the diameter of the circle that passes through the centers of those holes. For Saturn, the pattern is most often 5 lugs on a 100 mm circle (5x100), but some models and years use different patterns. Always confirm with official documents or measurements for your specific car.
Common patterns tied to Saturn models
Below is a general guide to patterns you may encounter across Saturn’s lineup, with typical groupings by model type.
Compact cars and early models (S-Series, Ion)
Most compact Saturns from the S-Series era and early Ion variants used the 5x100 mm pattern.
- 5x100 mm (5 on 100 mm) – common on S-Series and many early Ion models.
SUVs and larger models (Vue, Outlook, Astra-era variants)
Several Saturn SUVs and crossovers used a larger bolt circle, often 5x114.3 mm, depending on the year and platform sharing.
- 5x114.3 mm (5 on 114.3 mm) – seen on some Saturn SUVs and related crossovers.
Note that there are exceptions, including European-market variants and special editions, so always verify for your exact vehicle and year.
How to verify your Saturn's bolt pattern
Use these steps to determine the correct bolt pattern for your Saturn, ensuring you select compatible wheels and accessories.
- Consult the owner's manual or an official spec sheet for your model and year.
- Check the tire/wheel information sticker on the driver’s door jamb or inside the fuel-filler door for wheel specs.
- Measure the bolt circle directly: locate the centers of two opposite lug holes and measure the distance between them in millimeters. This is the bolt circle diameter (BCD).
- If you’re buying used wheels, confirm the pattern with the seller or compare with the car’s existing wheels.
With the correct bolt pattern identified, you can ensure wheels fit properly and avoid common issues related to hub bore size and offset.
Summary
Saturn did not have a single, universal bolt pattern. The most common pattern across many models is 5x100 mm, but some SUVs and other variants used 5x114.3 mm, and there are exceptions for European-market or special editions. Always verify for your specific year and model by consulting official documentation, the vehicle’s sticker, or a professional when in doubt.
