Tyre Pressures – A Critical but Often Overlooked Detail
Tyre pressure is one of the most commonly overlooked aspects of vehicle maintenance on BMW and MINI vehicles.
It’s easy to forget — especially when service station air pumps are busy or out of order. However, maintaining correct tyre pressure is essential for safety, performance, and tyre longevity.
Run Flat Tyres and Why They Still Need Attention
Most post 2003 BMW and MINI vehicles are fitted with star rated run-flat tyres from brands such as Bridgestone, Dunlop, Pirelli, Continental, and Michelin.
Run-flat tyres are designed to allow continued driving after a puncture at reduced speed, helping you reach a safe location for repair. However, they are not maintenance-free.
We recommend regularly inspecting your tyres for:
- Cuts or sidewall damage
- Cracks or ageing
- Tread depth and wear
- Correct tyre pressures
BMW Tyre Pressure Monitoring Systems (TPMS)
Your BMW or MINI is equipped with a tyre pressure monitoring system (TPMS) designed to alert you when pressure drops outside of safe limits.
While this system is an important safety feature, it is not a substitute for regular manual checks. It is designed to warn you of issues — not prevent them.
We recommend checking tyre pressures at least once a month when tyres are cold. This is actually often poorly understood and overlooked, but a hot tyre will have a higher pressure than a cold tyre.
How We Look After Your Tyres During Service
During every service at Stokes and Renk, we check and adjust tyre pressures according to BMW’s specifications.
If we identify uneven wear or incorrect pressures, we will provide clear recommendations tailored to your vehicle and driving style.
If replacement tyres are required, we can supply and fit premium performance tyres from leading manufacturers including Bridgestone, Dunlop, Continental, and others. We always recommend to use star rated tyres as per the BMW specifications
Why Correct Tyre Pressure Matters
Maintaining correct tyre pressure improves:
- Fuel efficiency
- Vehicle stability and braking performance
- Wet weather safety and grip
- Tyre lifespan
- Steering response and driving feel
Underinflated tyres in particular can lead to reduced handling performance, increased fuel consumption, and accelerated tyre wear.
Choosing the Correct Tyre Pressure
Recommended tyre pressures depend on several factors, including:
- Tyre size
- Driving style
- Vehicle load
In general:
- For everyday city driving, follow the tyre placard settings
- For long highway journeys with light load, placard settings remain ideal
- For heavier loads or extended highway travel, adjustments may be appropriate
The correct cold tyre pressures for your BMW or MINI are listed on the tyre placard, typically located inside the driver’s door near the driver’s seatbelt. Front and rear pressures often differ so be aware of that! You need to match the tyre size fitted to your vehicle with the size listed on the chart. If you are having difficulties understanding the chart, please reach out to us on 9381 1155.
