2020 Mercedes C-Class Wheel Bolt Torque: 130 N·m
2020 Mercedes C-Class Wheel Bolt Torque: 130 N·m with year and generation cautions, dry-thread guidance, tightening pattern.
The 2020 Mercedes-Benz C-Class Sedan operator's manual specifies a final wheel-bolt torque of 130 N·m (96 lb-ft). It directs a preliminary diagonal pass at no more than 80 N·m before the final pass.
The short answer for the most common 2020 C-Class Sedan application is 130 N·m, but wheel torque is a safety specification—not a value to guess from memory. Model year, platform, stud size, factory wheel design, and an aftermarket wheel manufacturer's instructions can change the required value. This guide therefore starts with the verified application table and then explains how to produce an accurate clamping load instead of merely making the wrench click.
Correct torque keeps the wheel seated evenly against the hub. Too little clamping force can let the wheel move and loosen the fasteners. Too much can stretch studs, damage the nut seat, distort a brake rotor, or make roadside removal impossible. Read the scope note, identify the vehicle and wheel, clean the mating surfaces, and use a calibrated torque wrench for the final passes.

Mercedes C Class Lug Nut Torque Spec
| APPLICATION / ITEM | SPECIFICATION | NOTES |
|---|---|---|
| Final wheel-bolt torque | 130 N·m | 96 lb-ft |
| Preliminary diagonal pass | Maximum 80 N·m | 59 lb-ft |
| Final order | 1–5 diagonal pattern | Repeat at full torque |
| Thread treatment | No oil or grease | Use approved undamaged bolts |
Use approved wheel bolts with the correct seat and effective length, keep the threads free of oil and grease, and start each bolt by hand. With the vehicle on the ground, tighten positions 1 through 5 diagonally to no more than 80 N·m, then repeat the same order at 130 N·m. Check tire pressure and restart the applicable pressure-loss or TPMS procedure after installation.
How to read the 2020 C-Class Sedan torque table
Start with model year and platform rather than wheel diameter. Factory 17-, 18-, and 20-inch wheels can share a value when they use the same stud and seat design, while two trucks sold in the same calendar year can differ because one is an outgoing platform. This exact two-stage procedure applies to the standard 2020 U.S.-market C-Class Sedan manual. AMG vehicles, another body style or model year, accessory wheels and changed fasteners must follow their own operator's manual or approved-wheel instructions.
The figures in this guide assume original-equipment-style fasteners and clean, dry threads unless the cited manufacturer says otherwise. If an aftermarket wheel, spacer, conversion stud, locking nut, or repair kit supplies a different instruction, that component-specific document controls. Record the final value on the work order so the next technician does not have to infer it.
Common mistakes that produce an unsafe wheel installation
Use approved wheel bolts with the correct seat and effective length, keep the threads free of oil and grease, and start each bolt by hand. With the vehicle on the ground, tighten positions 1 through 5 diagonally to no more than 80 N·m, then repeat the same order at 130 N·m. Check tire pressure and restart the applicable pressure-loss or TPMS procedure after installation. Treat an unfamiliar nut seat, stud, spacer, or wheel as a reason to stop and identify the hardware before tightening.
- Using a value from a different generation, heavy-duty model, or aftermarket wheel.
- Applying oil or anti-seize to a specification written for dry threads.
- Cross-threading with an impact gun instead of starting every nut by hand.
- Tightening clockwise around the circle instead of using an opposite-side pattern.
- Letting the full vehicle weight trap a wheel that is not yet centered on the hub.
- Skipping the confirmation pass and the post-service recheck.
Mercedes-Benz 2020 C-Class Sedan specifications can change by model year, engine, platform, wheel, and installed component. Confirm the VIN or engine identity, part numbers, fastener condition, and the current manufacturer instructions before service.
