A dual-drill, or multi-fit, wheel has two overlapping sets of lug holes machined into one mounting face, so a single rim bolts to two different bolt patterns. On our Rhino Predator, a title reading 139.7+127X10H means the wheel is drilled for both 5x139.7 mm and 5x127 mm patterns — ten holes in all. You mount it using only the five that match your vehicle.
What “139.7+127X10H” on our Rhino Predator actually means
The string is three pieces of information packed together:
- 139.7 — the first bolt circle: five lugs on a 139.7 mm circle (5x139.7).
- +127 — the wheel is also drilled for a second circle: five lugs on a 127 mm circle (5x127). The plus sign is what makes it dual-drill.
- X10H — ten holes total in the mounting face, because two five-lug patterns are machined into one wheel.
Bolt patterns get written in both metric and inch, which is why the same wheel can look like it has two names. Here is how the numbers on the Rhino Predator line convert, with the vehicle families each pattern is commonly found on. Treat the fitment column as a starting point and confirm against your own vehicle — year and trim change bolt patterns more often than people expect.
The safest way to confirm which pattern your vehicle uses is not to trust a generic car list — those are riddled with year and trim exceptions — but to measure your own hub. Count the studs, then measure the spacing using the method in our bolt pattern measuring guide, or read it off your existing wheel or owner's manual. Our truck and SUV bolt pattern guide explains the common truck patterns in more detail.
Our Rhino Predator ships as a dual-drill in three combinations — 139.7+127, 139.7+135, and 139.7+150 — plus a single-pattern 8x165.1 for eight-lug trucks. So the 5x139.7 circle is the common thread, and the second number tells you which additional family the same rim covers.
How to confirm your truck matches one of the two patterns
A dual-drill wheel fits your vehicle only if one full pattern lines up — not one that is close. Two ways to be sure:
- Look it up. Your factory bolt pattern is in the owner’s manual, on many tire-shop lookups, or stamped in build data by make, model, year and trim.
- Measure it. On a five-lug hub you measure from the center of one stud to the center of the stud two positions away (the “skip one” method), then match it to the chart. The measuring steps in our bolt-pattern measuring guide work the same on a truck hub as on a trailer hub. If you are cross-shopping trucks, our pickup bolt-pattern guide lists the common factory patterns by make.
Bolt pattern is only half of fitment. The number that follows it — offset — decides how far the wheel sits in or out. The Predator runs an aggressive negative offset, and the specifics differ by size:
| Predator size | Offset | Center bore | Dual-drill options | Sold as |
|---|---|---|---|---|
| 20x10 | -12 mm | 87.1–125 mm* | 139.7+127, 139.7+150, 8x165.1 | Set of 4 or 5 |
| 22x12 | -44 mm | 87.1–125 mm* | 139.7+127, 139.7+135, 139.7+150, 8x165.1 | Set of 4 or 5 |
*Center bore varies by pattern: 87.1 mm on the …/127 wheels, 110.3 mm on the …/150, and 125 mm on the 8x165.1. A -44 mm offset pushes the wheel well outward and needs fender and suspension clearance; before you commit, read our offset and backspacing guide to see how those millimeters change stance and clearance. Multi-pattern drilling is not only a truck-wheel trick — trailer wheels come in several patterns too (5x4.5, 6x5.5, 8x6.5), and the same rule applies; you can browse those in our trailer wheels collection.
Which holes to use when you mount — and how to torque
This is the part that matters for safety. On a dual-drill wheel the two bolt circles sit close together, so the holes look crowded. The rule is simple: use only the five holes of the single pattern that matches your vehicle, and never split lug nuts across both circles. The correct set is the one where all five studs pass through cleanly and the wheel sits flat against the hub with the lug seats centered.
- Match the lug seat. Aftermarket wheels like these typically use conical (tapered) lug seats. Confirm the seat type and use lug nuts made for the wheel, not just whatever came off your factory rims.
- Torque in a star pattern to your vehicle’s specified value, then re-check torque after roughly the first 10, 25, and 50 miles — new wheels settle and lugs can lose clamp load. We don’t publish a one-size torque number because it varies by vehicle; our lug-nut torque guide covers how to find and apply the right figure.
- Watch the center bore. To clear more than one hub, dual-drill wheels use a large center bore (the Predator runs 87.1–125 mm depending on pattern) and center on the lugs rather than the hub. If your hub is smaller than the bore and you feel vibration at speed, hub-centric rings sized to your hub help the wheel run true.
- Check the load rating. Confirm the load rating stamped on the wheel meets or exceeds your axle’s rating before you drive on it.
The trade-offs of a dual-drill wheel
Two patterns in one rim buys flexibility, with a few honest caveats.
- Wider fitment. One wheel covers two vehicle families, so it is easier to source and easier to resell — and if you switch trucks within the covered patterns, the wheels may carry over. It also means our Orlando warehouse can cover GM/Ram, Jeep, and Toyota buyers from one Predator line, which usually ships to the Southeast in 1–3 days with free shipping.
- More holes, closer together. Machining two circles leaves less material between some holes. Reputable dual-drills are engineered and rated for it, which is exactly why picking the correct five holes and torquing to spec is not optional.
- Lug-centric mounting. The large center bore means you may want hub-centric rings for a vibration-free ride, where a single-pattern hub-centric wheel might not need them.
- Not automatically “universal.” A dual-drill only fits the patterns actually drilled into it. That is why the title spells them out — a 139.7+127 wheel does nothing for a 6x135 Ford.
FAQ
Can I use some holes from each bolt pattern if my studs don’t quite line up?
No. Use only the five holes of the single pattern that matches your vehicle. Mixing holes across the two circles means the lug nuts won’t seat squarely, which can let them loosen. If neither pattern matches, the wheel is not right for your vehicle.
What does the “X10H” at the end of 139.7+127X10H mean?
It’s the total hole count in the mounting face — ten holes, because two five-lug patterns (5x139.7 and 5x127) are drilled into the same wheel. You still only use five holes at a time.
Do dual-drill wheels need hub-centric rings?
Often, yes. To clear more than one hub, dual-drill wheels use a large center bore (our Predator runs 87.1–125 mm depending on pattern) and center on the lugs. If your hub is smaller than the bore and you notice vibration, hub-centric rings sized to your hub help center the wheel.
