Before you look at a single wheel design, you need one number: your bolt pattern. Get it wrong and the wheel simply will not go on.
What a bolt pattern means
A bolt pattern such as 6x139.7 has two parts: the number of lug studs (6) and the diameter of the circle they sit on, in millimetres (139.7). You will also see it in inches — 6x139.7 is the same as 6x5.5.
How to find yours
- Check your owner's manual or the specs for your exact year, make and model.
- Count the lug nuts, then measure centre-to-centre across the circle (easy on even numbers: measure straight across between opposite studs).
- Or call us with the year, make and model and we will tell you.
Common patterns for the trucks we see most
| Truck | Bolt pattern |
|---|---|
| Ford F-150 (2004 onward) | 6x135 |
| Chevy Silverado 1500 / GMC Sierra 1500 | 6x139.7 |
| RAM 1500 (2019 onward, new body) | 6x139.7 |
| RAM 1500 (2012–2018) and 1500 Classic | 5x139.7 |
| Toyota Tacoma (2005 onward) | 6x139.7 |
| Toyota Tundra (2007–2021) | 5x150 |
| Toyota Tundra (2022 onward) | 6x139.7 |
| RAM 2500 / 3500 | 8x165.1 |
Bolt pattern is not the whole story. Offset, centre bore and brake clearance matter too — which is why we check the full fitment before a wheel is ordered, and why many aftermarket wheels need hub-centric rings.
