If you've landed here searching for the 2016 Ford Explorer bolt pattern, you likely fall into one of two camps: you need replacement wheels for your current Explorer, or you're scoping out this three-row SUV as a candidate for an electric vehicle conversion. Either way, you need precise measurements, not forum guesswork.
At AutoEdgeView, we typically review production EVs. But the custom EV conversion space is growing fast, and the 2012–2019 Ford Explorer (fifth generation, U502 platform) is one of the most popular donor vehicles thanks to its spacious chassis, strong aftermarket support, and readily available used examples. Before we get into EV conversion feasibility, let's nail down the hard wheel specifications.
2016 Ford Explorer Bolt Pattern: Exact Specifications
The 2016 Ford Explorer uses a 5-lug bolt pattern measuring 5x114.3mm (also expressed as 5x4.5 inches). This is one of the most common bolt patterns in the Ford ecosystem, shared with the Ford Edge, Ford Flex, Lincoln MKT, and many older Ford sedans.
| Specification | Value |
|---|---|
| Bolt Pattern (PCD) | 5x114.3mm (5x4.5") |
| Center Bore | 70.5mm |
| Thread Size (Lug Nut) | M14 x 1.5 |
| Stock Wheel Sizes | 18", 20" (trim dependent) |
| Stock Tire Sizes | 245/60R18, 255/50R20 |
| Offset Range (Stock) | +38mm to +44mm |
| Lug Nut Torque Spec | 150 lb-ft (203 Nm) |
The 70.5mm center bore is critical. If you're fitting aftermarket wheels with a larger bore, you'll need hub-centric rings to prevent vibration at highway speeds. Never rely on lug-centric mounting for a vehicle this heavy — the Explorer's curb weight ranges from 4,345 to 4,720 lbs depending on drivetrain.
Why the Bolt Pattern Matters for EV Conversions
When converting a gas-powered Explorer to electric, the bolt pattern dictates your wheel and hub motor options — and this is where the project gets interesting.
Hub Motor Compatibility
Aftermarket hub motors (like those from NetGain or QS Motor) must match the 5x114.3mm PCD. Many popular hub motors are drilled for 4-lug or 5x120mm patterns, meaning you may need custom adapters or machine work. Budget $400–$800 per adapter set if your chosen motor doesn't natively support 5x114.3.
Weight and Load Rating
An EV conversion adds significant weight. A typical Explorer EV swap adds 600–1,000 lbs of battery mass, pushing gross vehicle weight past 5,500 lbs. Your wheels must carry a load rating of at least 1,400 lbs per corner. Many lightweight aftermarket wheels designed for sedans won't meet this threshold. Stick to wheels rated for trucks, SUVs, or specifically for EV applications.
Regenerative Braking Considerations
EV conversions with strong regen (one-pedal driving setups) place different stress patterns on wheel bearings and hubs. The repeated torque pulses from regen braking — especially with hub motors — accelerate bearing wear. Plan for bearing inspection every 15,000 miles post-conversion.
The 2016 Explorer as an EV Conversion Donor: What You're Working With
Before committing to a conversion, understand what the donor vehicle brings to the table. The 2016 Explorer came with three powertrain options:
- 3.5L V6 (base): 290 hp, 255 lb-ft — most common, lightest front end
- 2.0L EcoBoost I4: 240 hp, 270 lb-ft — lighter, simpler engine bay
- 3.5L EcoBoost V6 (Sport): 365 hp, 350 lb-ft — heavier, more complex, AWD standard
For conversion purposes, the base 3.5L V6 with FWD is the preferred donor. It's the lightest variant (~4,345 lbs), has the simplest engine bay layout, and the removed engine/transmission weight (roughly 550 lbs combined) leaves more payload budget for batteries.
Available Space for Battery Packs
The fifth-gen Explorer offers several battery mounting zones:
- Engine bay: ~12 cubic feet after engine removal — fits 15–25 kWh of modules
- Fuel tank area (rear): ~4 cubic feet — fits 8–12 kWh
- Under-floor (custom pan): Possible but requires significant fabrication due to the unibody structure and exhaust tunnel
- Cargo area (behind third row): Sacrifices practicality but easiest to fabricate
Realistic total pack capacity: 35–50 kWh using Tesla modules, Nissan Leaf modules, or LG Chem packs. This translates to roughly 80–120 miles of range in a vehicle this heavy.
Realistic EV Conversion Range and Performance Expectations
Let's set expectations with real numbers. The 2016 Explorer is not an aerodynamic vehicle — its drag coefficient is approximately 0.35 Cd, and its frontal area is large. At highway speeds, it consumes energy aggressively.
- 35 kWh usable: ~70–80 miles (city), ~55–65 miles (highway at 70 mph)
- 45 kWh usable: ~90–105 miles (city), ~70–85 miles (highway at 70 mph)
- 50 kWh usable: ~100–120 miles (city), ~80–95 miles (highway at 70 mph)
Cold weather (below 32°F) reduces these figures by 20–35% due to battery chemistry limitations and cabin heating demands. Without a heat pump — which most conversions lack — resistive heating can draw 3–5 kW alone.
Performance Targets
A typical Explorer conversion using a NetGain Hyper 9 motor (or similar) produces 120–150 hp at the wheels. Expect 0–60 mph times in the 9–12 second range — adequate for daily driving but noticeably slower than the stock V6. Dual-motor setups can halve this but double the complexity and cost.
Charging Setup for a Converted Explorer
This is where most conversion projects underperform relative to production EVs. Here's what's realistic:
| Level | Power | Charge Time (0–100%, 45 kWh) | Equipment Cost |
|---|---|---|---|
| Level 1 (120V) | 1.4–1.9 kW | 24–32 hours | $200–$400 (onboard charger) |
| Level 2 (240V) | 3.3–6.6 kW | 7–14 hours | $500–$1,500 (charger + EVSE) |
| DC Fast Charge | 20–50 kW (if equipped) | 45–90 min (10–80%) | $2,500–$5,000 (CHAdeMO/CCS module) |
Most conversions top out at Level 2. Adding DC fast charging requires a compatible BMS, high-voltage contactors, and a CCS or CHAdeMO communication module. It's doable but adds significant cost and engineering time. Budget builds typically rely on 6.6 kW Level 2 charging, which means overnight charging is mandatory.
For home Level 2 installation, expect to pay $800–$2,500 total (EVSE unit plus electrician labor), assuming your panel has capacity for a 40-amp circuit. If you need a panel upgrade, add $1,500–$3,000. Always consult a licensed electrician for final specifications.
Conversion Cost vs. Buying a Production EV
This is the question that determines whether the project makes financial sense.
| Option | Total Cost | Range | Warranty | DC Fast Charge |
|---|---|---|---|---|
| Explorer Conversion (DIY) | $18,000–$35,000* | 70–120 mi | None | Rarely |
| Explorer Conversion (Shop) | $45,000–$75,000 | 100–150 mi | Limited (1–2 yr) | Sometimes |
| Used Tesla Model Y (2022) | $28,000–$35,000 | 303–330 mi (EPA) | Remaining factory | Yes (250 kW) |
| Used Ford Mustang Mach-E (2022) | $27,000–$34,000 | 230–314 mi (EPA) | Remaining factory | Yes (150 kW) |
| New Hyundai Ioniq 5 (2026) | $42,000–$52,000 | 290–325 mi (EPA) | Full factory + 10yr battery | Yes (up to 350 kW) |
*Donor vehicle cost ($6,000–$12,000 for a clean 2016 Explorer) is included in these figures.
The math is sobering. A professionally converted Explorer costs as much as a new Ioniq 5 with one-third the range, no warranty, and no fast charging. DIY conversions narrow the gap but demand hundreds of hours of skilled labor and offer no safety certifications.
When Does a Conversion Make Sense?
Consider converting if:
- You need three rows of seating and cannot find a production EV that fits your budget (though the Kia EV9 now exists)
- You value the learning experience and have fabrication/electrical skills
- You have a specific sentimental attachment to the vehicle
- You plan to use it as a short-range local vehicle (school runs, errands under 40 miles)
Buy a production EV if:
- You need reliable daily transportation with warranty coverage
- You regularly drive more than 100 miles per day
- You want DC fast charging for road trips
- You want to qualify for federal or state EV incentives
Federal Tax Credits and Converted EVs
Here's a critical point many conversion enthusiasts overlook: EV conversions do not qualify for the federal §30D tax credit. The IRS requires that qualifying vehicles be new clean vehicles purchased from a manufacturer with proper certification. A home-converted vehicle doesn't meet these criteria.
This means a $35,000 conversion costs you the full $35,000, while a $42,000 new Ioniq 5 could net a $7,500 point-of-sale credit (if you meet income and sourcing requirements), bringing its effective cost to $34,500 — less than the conversion, with triple the range and a full warranty.
Current §30D eligibility requirements include:
- Adjusted gross income below $150,000 (single) or $300,000 (joint)
- Vehicle MSRP under $55,000 (sedans) or $80,000 (SUVs/trucks)
- Battery components and critical minerals meeting North American sourcing thresholds
- Vehicle must be new and purchased from a licensed dealer
Always verify current-year rules on IRS.gov before making purchase decisions, as requirements update annually.
Wheel and Bolt Pattern FAQ
What is the bolt pattern on a 2016 Ford Explorer?
The 2016 Ford Explorer has a 5x114.3mm (5x4.5 inch) bolt pattern with a 70.5mm center bore and M14 x 1.5 lug nuts torqued to 150 lb-ft.
Can I use 5x120 wheels on a 2016 Explorer?
No. The 5x120 pattern (common on BMW and some GM vehicles) will not fit the Explorer's 5x114.3 hubs. Adapters exist but add unsprung weight and stress — not recommended for a heavy SUV, especially one carrying additional EV battery mass.
What wheels from other vehicles fit the 2016 Explorer?
Vehicles sharing the 5x114.3 pattern with similar offset (+38 to +44mm) and 70.5mm or larger center bore include: Ford Edge (2015+), Ford Flex, Lincoln MKX/MKT, Toyota Highlander (2014+), Honda Pilot (2016+), and Hyundai Santa Fe (2013+). Always verify load rating and center bore compatibility.
Is the 2016 Ford Explorer a good EV conversion candidate?
It's viable but not optimal. The Explorer is heavy (4,300+ lbs), aerodynamically poor, and has limited under-floor battery space. You'll achieve 70–120 miles of range at significant cost. If you need three-row EV seating, the Kia EV9 (300+ mile range, available used from ~$45,000) is a far more practical solution.
Will converting to EV change the wheel bearing load?
Yes. Battery weight adds 600–1,000 lbs to the vehicle, increasing static and dynamic loads on wheel bearings. Additionally, regenerative braking creates torque pulses that accelerate bearing wear. Use high-quality bearings and inspect them at 15,000-mile intervals post-conversion.
