Daily driving
Ultra-high performance summer
Hot-tier power starts to overwhelm touring rubber, especially in the wet. UHP tyres add the braking and steering you need and still last.

- Whatever your placard shows: it is the authority. Our rough estimate for this car laden is 89 (580 kg per tyre).
- Treadwear (UTQG)
- 300–400 for UHP summer tyres; expect 30,000–50,000 km.
Estimates from power and weight. The tyre placard on the driver’s door jamb is the legal minimum.

Things to know about the A 45 S
All-wheel drive: replace all four
Keep all four tyres the same make, model and near-identical tread depth. Many AWD systems tolerate only 2–3 mm of difference before the centre coupling or diff is strained, so a single damaged tyre can mean replacing the set, or shaving a new one to match.
Buying only two?
On AWD, avoid it. On other cars, put the new pair on the rear axle: grippy rears keep the car stable when braking or cornering in the wet.
