BMW 8 Series Convertible 2022-2023 Runflat tires User Manual
Runflat tires
Principle
Run-flat tires permit continued driving under restricted conditions even in the event of a complete tire pressure loss.
General information
The wheels consist of tires that are self-supporting, to a limited degree and possibly special rims. The reinforcement of the sidewall allows the tire to remain drivable to a restricted degree in the event of a tire pressure loss. Follow the instructions for continued driving with a flat tire.
Safety information
Warning
The vehicle handles differently when a run-flat tire has insufficient or no tire pressure; for instance, reduced lane stability when braking, braking distances are longer and the self-steering properties will change. There is a risk of an accident. Drive moderately and do not exceed a speed of 50 mph/80 km/h.
Identification
The tires are marked on the tire sidewall with Run-flat System Component RSC.
Repairing a flat tire
Safety measures
- Park the vehicle as far away as possible from passing traffic and on solid ground.
- Turn on the hazard warning system.
- Secure the vehicle against rolling away by setting the parking brake.
- Turn the steering wheel until the front wheels are in the straight-ahead position and engage the steering wheel lock.
- Have all vehicle occupants get out of the vehicle and ensure that they remain outside the hazardous area in a safe place, such as be‐hind a guardrail.
- If necessary, set up a warning triangle at an appropriate distance.
Tire repair set
Principle
With the tire repair set, minor tire damage can be sealed temporarily to enable continued driving.
General information
- To enable continued driving, the liquid sealant is pumped into the tire, which hardens and seals the damage from the inside.
- Follow the instructions on using the tire repair set found on the compressor and sealant bottle.
- Use of the tire repair set may be ineffective if the tire puncture measures approx. 4 mm or more.
- Contact a dealer’s service center or another qualified service center or repair shop if the tire cannot be made drivable.
- Do not remove foreign bodies that have penetrated the tire. Remove foreign objects only when they are visibly protruding from the tire.
- Pull the speed limit sticker off the sealant bottle and apply it to the steering wheel.
- The use of a sealing compound can damage the wheel electronics. In this case, have the electronics checked and replaced at the next opportunity.
- The compressor can be used to check the tire inflation pressure.

Filling the tire with sealing compound
Safety information
DANGER
If the exhaust pipe is blocked or ventilation is insufficient, harmful exhaust gases can enter the vehicle. The exhaust gases contain pollutants that are colorless and odorless. In enclosed areas, exhaust gases can also accumulate outside of the vehicle. There is a danger to life. Keep the exhaust pipe free and ensure sufficient ventilation.
NOTICE
The compressor can overheat during extended operation. There is a risk of damage to property, among other potential damage. Do not run the compressor for more than 10 minutes.
Filling
- Shake the sealant bottle.
- Pull filler hose completely out of the cover of the sealant bottle. Do not kink the hose.
- Slide the sealant bottle into the holder on the compressor housing, ensuring that it engages audibly.
- Screw the filler hose of the sealant bottle onto the tire valve of the nonworking wheel.
- With the compressor switched off, insert the connector into the power socket in the vehicle interior.
- With the standby state or drive-ready state switched on, switch on the compressor.
Let the compressor run for max. 10 minutes to fill the tire with sealing compound and achieve a tire inflation pressure of approx. 2.0 bar. While the tire is being filled with sealing compound, the tire inflation pressure may sporadically reach approx. 5 bar. Do not switch off the compressor in this phase.
