2007 Dodge Ram 1500 Bolt Pattern: The Exact Numbers
If you're replacing wheels, upgrading brakes, or planning an electric-vehicle conversion on a 2007 Dodge Ram 1500, getting the bolt pattern right is non-negotiable. Here is the definitive fitment data for this third-generation (2002–2008) half-ton truck.
| Specification | Value |
|---|---|
| Bolt Pattern (metric) | 5 × 139.7 mm |
| Bolt Pattern (imperial) | 5 × 5.5 inches |
| Lug Count | 5 lugs |
| Lug Nut Thread Size | 1/2"-20 UNF (right-hand thread) |
| Lug Nut Torque Spec | 130 lb-ft (176 N·m) |
| Center Bore | 77.8 mm (3.06") |
| Recommended Offset Range | +15 mm to +25 mm (OEM wheels) |
| OEM Wheel Diameter | 17" (standard), 20" (optional) |
| OEM Tire Size (common) | 265/70R17 or 275/60R20 |
The 5×139.7 mm (also written as 5×5.5") bolt pattern means five lug holes arranged on a circle with a 139.7 mm diameter. This is the same pattern Dodge used across Ram 1500 model years from 1994 through 2018, and it is shared with several other vehicles, including older Ford F-150 models (pre-2004), some Jeep Grand Cherokee years, and certain Toyota Land Cruiser variants.
Understanding the 5×139.7 mm (5×5.5") Pattern
Bolt patterns are expressed as number of lugs × bolt circle diameter. The bolt circle diameter (BCD) is measured from the center of one lug hole to the far side of the circle passing through all lug centers. For a 5-lug pattern, you measure from the back of one lug hole to the center of the lug hole directly across from it.
Common Confusion: 5×139.7 vs. 5×140
Some aftermarket listings round 139.7 mm up to 140 mm. In practice, a 5×140 wheel will not seat properly on a 5×139.7 hub — the 0.3 mm difference per lug creates binding or vibration. Always match the exact specification. Hub-centric rings can solve center bore mismatches (e.g., fitting a 73.1 mm bore wheel onto the Ram's 77.8 mm hub), but they cannot correct a bolt circle mismatch.
Vehicles Sharing the 5×139.7 Bolt Pattern
- 1994–2018 Dodge Ram 1500 (all trims)
- 1997–2003 Ford F-150 (heritage body)
- 1999–2004 Ford F-150 (certain years)
- 1980–1997 Ford F-150 / Bronco
- Jeep Grand Cherokee WJ/WK (1999–2010)
- Toyota Land Cruiser 80/100 Series (certain years)
- Suzuki Samurai / Vitara (some years)
This cross-compatibility opens up wheel sourcing options, but always verify offset, center bore, and load rating independently — bolt pattern alone does not guarantee fitment.
Lug Nut Specs and Torque Requirements
The 2007 Ram 1500 uses 1/2"-20 UNF lug nuts with a recommended torque of 130 lb-ft. This is critical for safe operation and becomes even more important if you're adding the weight of an EV conversion.
| Configuration | Torque (lb-ft) | Torque (N·m) | Notes |
|---|---|---|---|
| Steel wheels (OEM) | 130 | 176 | Re-torque after 50 miles |
| Alloy wheels (OEM) | 130 | 176 | Use conical-seat lug nuts |
| Aftermarket wheels | 100–130 | 135–176 | Follow wheel manufacturer spec |
| EV conversion (loaded) | 130 | 176 | Re-check every 5,000 mi |
Lug nut seat type: The OEM wheels use a 60-degree conical (acorn) seat. If you install aftermarket wheels with a flat (mag) seat or ball (spherical) seat, you must use matching lug nuts. Mismatched seats cause uneven clamping force and potential wheel separation.
Center Bore and Hub-Centric Fitment
The 2007 Ram 1500 has a 77.8 mm center bore. This is the hole in the center of the wheel that fits over the hub. A proper hub-centric fit means the hub — not the lug nuts — centers the wheel, reducing vibration at speed.
If you source wheels from a vehicle with a smaller center bore (e.g., 73.1 mm from many aftermarket brands), they physically will not mount. Wheels with a larger center bore (e.g., 78.1 mm or 106.1 mm) can be fitted using hub-centric rings — plastic or aluminum spacers that fill the gap between the hub and the wheel bore. These rings cost $15–$40 per set and are essential for vibration-free driving.
Wheel and Tire Fitment for the 2007 Ram 1500
Beyond the bolt pattern, proper wheel fitment depends on offset, backspacing, width, and tire diameter. Here are the parameters that work on this truck:
| Parameter | OEM Range | Aftermarket Safe Range |
|---|---|---|
| Wheel Width | 7"–8" | 7"–10" |
| Offset (ET) | +15 to +25 mm | +0 to +30 mm |
| Backspacing | 4.5"–5.5" | 4"–6" |
| Max Tire Diameter | 31.5" (stock) | 33" (no lift), 35" (2" lift) |
| Wheel Diameter | 17"–20" | 16"–22" |
Offset and Suspension Clearance
Offset determines how far the wheel sits inward or outward relative to the hub mounting surface. The 2007 Ram 1500's front suspension uses an independent short-long-arm (SLA) design with upper and lower control arms. Running too low an offset (e.g., ET-10 or negative offset) pushes the wheel outward, increasing scrub radius and placing additional stress on wheel bearings — a particular concern when adding EV drivetrain weight.
For an EV conversion, aim for the higher end of the offset range (+20 to +30 mm) to keep the wheel centerline close to the bearing centerline. This minimizes the additional bearing load from the heavier vehicle.
EV Conversion Considerations: Bolt Pattern and Beyond
The 2007 Ram 1500 is an increasingly popular platform for electric conversions. Its body-on-frame construction, generous engine bay, and 5×139.7 bolt pattern make it a practical donor vehicle. Here's what EV builders need to know about wheels and fitment in this context.
Weight Increase and Load Rating
A typical Ram 1500 EV conversion adds 600–1,200 lbs over the stock curb weight of approximately 5,100 lbs (regular cab, 4×2). This puts the converted vehicle at 5,700–6,300 lbs or more. Every wheel has a load rating stamped on the back — for a stock Ram 1500, OEM wheels are rated at approximately 2,300 lbs per corner. After an EV conversion, you need wheels rated for at least 1,575 lbs per corner (6,300 ÷ 4), but ideally higher to provide a safety margin for dynamic loads (cornering, braking, potholes).
Look for wheels with a minimum load rating of 2,500 lbs per corner. Many aftermarket 5×139.7 wheels designed for trucks and SUVs meet or exceed this. Avoid passenger-car wheels, which may be rated for only 1,300–1,500 lbs per corner.
Tire Selection for Heavier EV Loads
Heavier vehicles need tires with higher load indexes and stiffer sidewalls. For a converted Ram 1500 EV:
- Load Index: Minimum 115 (2,679 lbs per tire); 121 (3,307 lbs) preferred
- Speed Rating: S (112 mph) minimum; H (130 mph) preferred for highway margins
- Tire Type: LT (Light Truck) metric tires are designed for higher loads and are recommended over P-metric (passenger) tires
- EV-Specific Tires: Brands like Michelin (e·Primacy), Hankook (iON), and Continental (EcoContact 6 EV) offer tires optimized for EV weight and instant torque characteristics, with reinforced sidewalls and low rolling resistance
Regenerative Braking and Wheel Stress
EV conversions with strong regenerative braking (0.2–0.4g deceleration) place cyclic torque loads on the wheel-lug interface in the opposite direction from acceleration. Ensure your lug nuts are torqued to spec and re-checked at 500-mile intervals during the initial break-in period. Some builders upgrade to ARP wheel studs (part number 100-77200 for 1/2"-20 thread) for added tensile strength.
How to Measure and Verify Your Bolt Pattern
If you want to confirm the bolt pattern on your specific 2007 Ram 1500 (especially if the hubs have been modified by a previous owner), here's how to measure it:
- Count the lugs. The Ram 1500 has 5 lugs per wheel.
- Measure the bolt circle diameter. For a 5-lug pattern, measure from the back (outer edge) of one lug hole to the center of the lug hole that is furthest from it (not directly opposite, since 5 is an odd number). This distance is the bolt circle diameter.
- Verify the measurement. You should get approximately 139.7 mm (5.5 inches). If you measure 127 mm (5"), you may have a different hub or adapter installed.
- Check the center bore. Measure the diameter of the hub pilot hole. Stock is 77.8 mm.
- Use a bolt pattern gauge. Available for $15–$30 from auto parts stores, these plastic templates slide over the lugs and instantly identify the pattern.
If your measurement doesn't match 5×139.7 mm, check whether wheel adapters or spacers are installed between the hub and the wheel. Some previous owners install adapters to run wheels from other vehicles (e.g., 6-lug to 5-lug adapters, or 5×139.7 to 5×127 adapters for Jeep Wrangler wheels).
Where to Source Compatible Wheels
The 5×139.7 bolt pattern is common enough that you have many sourcing options:
- OEM Mopar wheels: Available through Dodge dealers or used from salvage yards. 17" and 20" options exist. Typical used cost: $75–$200 per wheel.
- Aftermarket brands: Method Race Wheels, Fuel Off-Road, American Racing, and Pro Comp all offer 5×139.7 options. New cost: $180–$450 per wheel.
- Cross-platform take-offs: Wheels from 1997–2003 Ford F-150s or 1999–2010 Jeep Grand Cherokees with the same bolt pattern can fit, provided offset and center bore are compatible.
- EV-rated specialty wheels: Companies like Konig and TSW offer flow-formed wheels in 5×139.7 that are lighter than cast alternatives — beneficial for EV range since unsprung weight directly impacts efficiency.
Frequently Asked Questions
What is the bolt pattern for a 2007 Dodge Ram 1500?
The bolt pattern is 5×139.7 mm, also expressed as 5×5.5 inches. This means 5 lug holes on a 139.7 mm bolt circle diameter. The center bore is 77.8 mm, and lug nuts are 1/2"-20 UNF torqued to 130 lb-ft.
Will 5×5 wheels fit a 2007 Ram 1500?
No. A 5×5 pattern (5×127 mm) is 12.7 mm smaller in bolt circle diameter than the Ram's 5×139.7 mm. They will not bolt on without adapters, and adapters introduce additional failure points and change offset. Avoid this setup, especially for an EV conversion carrying extra weight.
Can I use Ford F-150 wheels on my 2007 Ram 1500?
Wheels from 1980–2003 Ford F-150s with the 5×139.7 (5×5.5") bolt pattern will physically bolt on. However, you must verify center bore compatibility (Ford's hub bore is 87.1 mm on many years, which is larger than the Ram's 77.8 mm hub — hub-centric rings would be needed in reverse, which is not possible; the wheel would sit lug-centric). Ford wheels from 2004+ F-150s switched to a 6×135 mm pattern and will not fit.
What size wheels fit a 2007 Dodge Ram 1500?
The OEM wheel sizes are 17" (standard) and 20" (optional, typically on Laramie or Sport trims). Aftermarket wheels from 16" to 22" can fit, provided they have the correct 5×139.7 bolt pattern, appropriate offset (+0 to +30 mm), and sufficient center bore (≥77.8 mm or use hub-centric rings for larger bores).
Is the bolt pattern the same for 2WD and 4WD 2007 Ram 1500 models?
Yes. Both 2WD and 4WD 2007 Ram 1500 models use the same 5×139.7 mm bolt pattern. The difference between 2WD and 4WD is in the front hub assembly (4WD has a drive flange), but the lug pattern and center bore remain identical.
How much does it cost to replace all four wheels on a 2007 Ram 1500?
Used OEM wheels run $300–$800 for a set of four. New aftermarket wheels range from $720–$1,800 for a set. For an EV conversion, budget $1,000–$2,000 for a set of load-rated, hub-centric aftermarket wheels — don't compromise on wheel quality when carrying battery weight.
