MG S5Fitment Strategy
MG S5 fitment starts with the actual vehicle, brake package, ride height, tyre load index, and hub specification. This guide records the live LFI worksheet case and gives the sizing direction LFI will refine before production.
Confirm the car.
Model year, brake package, suspension height, and alignment are checked before production.
Confirm the wheel.
Width, offset, centre bore, load rating, concavity, hardware seat, and finish are built as a single specification.
Confirm the tyre.
Tyre section width, shoulder shape, rolling diameter, and load index decide whether the final stance is clean or compromised.

Wheel SizeStarting Points
| Setup | Use case | LFI notes |
|---|---|---|
| 19x8.5 ET36 square | Daily-road EV fitment with OEM-friendly width and clean arch fill. | Final offset, tyre model, load index, and brake profile are confirmed before production. |
| 19x9 ET34-38 square | For owners wanting a slightly fuller shoulder, subject to tyre brand and ride height. | Final offset, tyre model, load index, and brake profile are confirmed before production. |
| 20x8.5 ET35-40 square | Diameter-up option for visual presence after confirming total tyre diameter. | Final offset, tyre model, load index, and brake profile are confirmed before production. |
Load RatedFor The Vehicle
Wheel strength is matched to vehicle load, tyre load index, brake torque, and the intended duty cycle. LFI checks these values before machining and finishing each forged wheel set.
Load-rating margin
Candidate wheel load ratings are compared against the vehicle axle-load target so the final build has an appropriate reserve for road use, EV mass, passengers, and luggage.
Torque-load target
Brake torque is part of the wheel story. For this platform LFI uses a rounded static torque-load target of 2,200 Nm for engineering review.
| Candidate load | Margin vs axle baseline | Status |
|---|---|---|
| 690 kg | +5% | Road baseline |
| 790 kg | +20% | Preferred |
| 890 kg | +35% | Extra reserve |
| Load case | Validation focus | Production check |
|---|---|---|
| Radial vehicle load | Vehicle mass, passengers, luggage, and tyre load index. | Wheel load rating selected for the final duty cycle. |
| Torque load | Static brake torque target of 2,200 Nm. | Centre pad, spoke root, and bolt pad reviewed together. |
| Cornering load | Tyre grip, wheel width, offset, and suspension geometry. | Spoke, lip, and barrel profile confirmed before machining. |
| Combined static load case | Radial, torque, and lateral demand considered as one wheel system. | Final LFI drawing is checked before production release. |
BeforeProduction
Brake clearance
Caliper envelope, barrel drop, and spoke clearance are checked against the chosen wheel face.
Tyre clearance
Tyre brand, section width, shoulder shape, rolling diameter, and ride height are reviewed together.
Hub hardware
Centre bore, PCD, hardware seat, and cap plan are locked before machining.
Do Not CopyBlindly
MG S5 fitment should not be copied from another car without checking ride height, brake package, tyre model, suspension clearance, and local load requirements. Use these rows as starting points, not as a universal guarantee.

MG S5Questions
What is the documented MG S5 customer build in this guide?
Build #20-1736 records a 2026 MG S5 using LFI MF912 in 19x8.5 ET36 square with 5x112 / 66.56 hub specification. Final tyre and clearance details are confirmed against the actual vehicle before production.
Can LFI build other MG S5 sizes?
Yes. LFI can adjust width, offset, centre bore, brake profile, finish, and wheel load rating after reviewing the vehicle, suspension height, tyre target, and brake package.
Why does this MG S5 guide not use the Monday media uploads as case photos?
The available media for this row was not suitable as a final on-car customer photo set. LFI keeps wheel-only, note, or engineering-only media out of fitment case galleries until full-car or installed-on-car media is available.
Does LFI confirm load rating for the MG S5?
Yes. LFI confirms wheel load rating, tyre load index, brake clearance, centre-bore configuration, and hardware seat before production.
