Wheel Center Cap Compatibility Guide by Bolt Pattern
Share
"Will this center cap fit my wheel?" It's the most common question we get — and the answer almost always comes down to two things: your wheel's center bore diameter and, in some cases, your bolt pattern. This guide explains how bolt pattern relates to center cap fitment and how to find a compatible cap for the most popular configurations.
Does Bolt Pattern Directly Affect Center Cap Size?
Not always — but there's a strong correlation. Bolt pattern determines the spacing of your lug holes, which in turn influences how large the center bore needs to be. Larger bolt patterns (common on trucks and SUVs) typically have larger center bores, which require larger caps.
Here's a quick reference:
| Bolt Pattern | Common Vehicles | Typical Center Bore |
|---|---|---|
| 5x4.5 (5x114.3) | Honda, Toyota, Ford Mustang | 60mm–67mm |
| 5x5 (5x127) | Jeep Wrangler, Chevy Tahoe | 71mm–78mm |
| 6x5.5 (6x139.7) | Chevy/GMC trucks, Toyota Tundra | 78mm–108mm |
| 6x135 | Ford F-150 (2004+), Expedition | 87mm–108mm |
| 8x6.5 (8x165.1) | Ram 2500/3500, GM HD trucks | 116mm–125mm |
Brand-Specific Fitment Notes
Fuel Off-Road
Fuel wheels use a proprietary cap system. Most Fuel caps are not interchangeable across wheel lines — always match by the specific Fuel part number. Browse Fuel Off-Road caps and filter by your wheel model.
American Racing
American Racing has produced wheels since 1956, and cap fitment varies significantly across generations. Older AR wheels (pre-2000) often use a different bore size than current production. Check the part number stamped on your existing cap or wheel barrel. Browse American Racing caps.
Vision, Ion, Mayhem
These brands share some parent-company tooling, so caps occasionally cross-fit between lines — but always verify by part number before ordering.
How to Confirm Compatibility Before You Order
- Find your existing cap's part number — stamped on the back or inside the cap
- Measure your center bore — inner diameter of the wheel's center hole
- Note your bolt pattern — found in your vehicle owner's manual or door jamb sticker
- Search by part number on The Center Cap Store for an exact match
- Check the product listing for listed compatible bolt patterns and bore sizes
