BYD Atto 3
Customer-specification fitment guide for the BYD Atto 3. 19x8J ET38 square MF101, 5x114.3, 60.1 mm hub-centric, Platinum Black. Built from a recorded customer car, not a calculator.
The Atto 3 carries EV battery mass on a compact SUV platform. Wheel weight, load rating, hub-centric accuracy, and tyre load index all matter — not just offset. The specification below is built from a recorded customer car.
Real Case Reference
LF21112022_594 gives Atto 3 owners a real 19x8J ET38 MF101 starting point instead of a generic calculator result.
EV Load Review
The battery mass and SUV body shape make wheel load target, tyre load index, and road duty cycle part of the quote process.

|---|---|---|
| PCD | 5x114.3 | Customer invoice reference; confirm exact car before machining. |
| Centre bore | 60.1 mm | Machine hub-centric to the confirmed Atto 3 hub. |
| Factory tyre reference | 235/50R18 | Use official-market tyre data as a baseline, then review final rolling diameter. |
| Customer case wheel | 19x8J ET38 square | Photo-backed LFI MF101 Design case in Platinum Black. |
| Body type | Compact EV SUV | Review load target, brake clearance, tyre shoulder, and road-use comfort together. |
This BYD Atto 3 case uses a square 19x8J ET38 MF101 forged monoblock specification. The setup keeps the car practical and rotation-friendly while giving the side profile a cleaner wheel face and a darker Platinum Black finish.
The wheel was specified with 5x114.3 PCD and 60.1 mm hub-centric machining, matching the build record rather than relying on loose universal fitment.
The primary row is the real LFI customer case. Alternate rows are fitment directions for quoting, then LFI confirms tyre, brake, fender, load, and ride-height details before production.
| Direction | Wheel size | Suggested tyre direction | Best for | Notes |
|---|---|---|---|---|
| Comfort / OEM+ | 18x7.5 to 18x8 ET40-45 | Factory-type 235/50R18 | Daily comfort and range discipline | Good starting point when the owner wants forged response without reducing tyre sidewall. |
| Customer proven | 19x8J ET38 | Confirm per target rolling diameter | MF101 photo-backed street stance | LF21112022_594 reference case; check tyre shoulder and brake clearance before repeating. |
| Sport visual | 19x8.5 ET40-45 | 235 to 245 section width | More face depth and tyre support | Works as a quote direction only after tyre load index, fender, and inner clearance are reviewed. |
Wheel strength is not a single number. Vertical load, braking torque, drive torque, spoke-root stress, hub-pad stress, and bolt-seat behavior are all part of the engineering package — validated together, not in isolation.
BYD publishes maximum axle loads of 1070 kg front and 1110 kg rear for the Atto 3. LFI uses the heavier rear axle as the wheel-load reference, so 690 kg per wheel is the preferred road-use target in this guide, with higher ratings treated as extra reserve.
Wheel strength is not only vertical load. LFI also reviews acceleration, braking, cornering, potholes, hub-pad stress, bolt-seat stress, spoke-root stress, and rim-barrel torque reaction against an approximately 2,100 Nm per wheel static torque-load target.
| Wheel load rating | Per-axle equivalent | Margin vs axle baseline | Status | How LFI positions it |
|---|---|---|---|---|
| 690 kg | 1380 kg per axle | +24% | Preferred | Preferred road-use direction when tyre load, duty cycle, and exact vehicle details are confirmed. |
| 790 kg | 1580 kg per axle | +42% | Extra reserve | Useful for repeated highway use, harsher roads, heavier tires, and extra reserve. |
| 850 kg | 1700 kg per axle | +53% | Extra reserve | Useful when the build prioritises maximum reserve or harsher-road use. |
| Validation load case | Reference basis | Suggested LFI target | Why it matters |
|---|---|---|---|
| Radial vehicle load | Manufacturer axle-load data, passengers, cargo, tyre package, and selected wheel load target | 690 kg preferred target; 790 kg or 850 kg for extra reserve where the wheel family allows it | Vehicle mass and sustained road loading. |
| Torque load | Conservative 1g dry-braking review | ~2,100 Nm per wheel | Loads the hub pad, bolt seats, spoke roots, and rim barrel. |
| Cornering load | Lateral force from road grip, tyre shoulder, and fast-road use | Application-specific | Lateral loading under cornering. |
| Combined static load case | Radial load + torque load + cornering load | Application-specific | Real-world loads are combined, not isolated. |
Engineering Article
For forged wheel applications, vertical load is only one part of the engineering picture. LFI also reviews spoke-root stress, hub-pad loading, bolt-seat behavior, rim-barrel stress, and combined static road-load cases where relevant.
| Term | Meaning | How it applies to LFI custom wheels |
|---|---|---|
| JWL | Japanese technical standard for light alloy wheels. | Used as a reference standard for relevant load and durability requirements. |
| VIA | Japanese third-party wheel test registration system. | Applies only to specific wheel models/specifications that are formally registered. |
| FEA | Finite element review of wheel stress under defined load cases. | LFI uses engineering review to check hub, spoke, bolt-seat, rim, and combined-load behavior. |
| Road validation | Fitment, vibration, brake, and tyre-clearance checks on the actual car. | Required before repeating aggressive visual targets across trims or tyre brands. |
This case is the direct reference for Atto 3 owners who want a clean 19 inch forged setup without turning the car into a harsh, fragile-looking SUV build. The side-profile photo shows the Platinum Black MF101 design sitting naturally under the Atto 3 body line.
These models are selected around compact-EV SUV needs rather than generic forged-wheel fallback.

The Atto 3 customer case in this guide uses 5x114.3 PCD. LFI still confirms the exact vehicle before machining because market, model year, hub, hardware, and brake details matter.
This LFI Atto 3 case was specified with a 60.1 mm centre bore. LFI machines the wheel hub-centric to the confirmed car instead of relying on a generic oversized bore where possible.
The photo-backed customer case is LF21112022_594: 19x8J ET38 square, 5x114.3 PCD, 60.1 mm centre bore, LFI MF101 Design, and Platinum Black finish.
Yes. The 19x8J ET38 square setup is a clean customer-proven reference for a street Atto 3 build when tyre shoulder, brake clearance, and ride height are checked together.
Yes. An 18 inch forged setup can keep more tyre sidewall, reduce road harshness, and protect range and ride quality, especially for daily Singapore road use.
Many Atto 3 variants use an 18 inch factory tyre package. If moving to 19 inch, LFI checks rolling diameter, load index, tyre shoulder, and clearance before confirming the tyre.
Yes, when the offset, brake clearance, centre bore, and face profile are engineered into the wheel specification. The goal is a direct-fit forged setup, not a spacer-dependent workaround.
The Atto 3 is a compact SUV-sized EV with battery mass, so LFI reviews wheel load rating, tyre load index, road use, and duty cycle together before production.
Using BYD published maximum axle-load data, 690 kg per wheel is the preferred road-use target for the Atto 3 directions in this guide. 790 kg and 850 kg add extra reserve for harsher-road, heavier-tyre, or high-speed use.
It is LFI's practical static validation target for selected Atto 3 forged wheel specifications. It helps evaluate the hub pad, bolt seats, spoke roots, and barrel under braking and drive torque.
They can improve steering response, braking feel, suspension control, and the sense of effort at the wheel compared with heavier cast wheels, while still respecting EV load requirements.
Often yes, if the cap diameter, clip style, pocket depth, and face design are planned before production. LFI confirms this during the build draft.
A staggered visual setup may be possible, but a square setup is normally cleaner for tyre rotation, predictable handling, EV efficiency, and simpler replacement tyre planning.
Yes. Spoke profile, barrel clearance, backpad, balancing-weight clearance, and final offset are checked before a forged wheel is produced.
Send the model year, variant, current tyre size, target wheel size, desired stance, brake package photos if available, ride height, centre-cap preference, finish preference, and intended driving use.
Yes. LFI supports Singapore and Malaysia customers locally and prepares international BYD forged wheel orders with remote fitment consultation and DDP shipping where available.
Yes. Platinum Black is the finish shown on the LF21112022_594 case. LFI can quote black, brushed, polished, bronze, silver, and custom finishes depending on the wheel design.
No. The MF101 case is a real fitment reference. LFI can adjust width, offset, concavity, finish, and tyre pairing around the exact Atto 3 and owner priorities.
Send LFI your model year, variant, current tyre size, target wheel size, finish preference, centre-cap plan, and whether your priority is comfort, range, visual stance, lighter response, or higher load reserve.
