245/40 R21 Tyre Review Highlights

Writing about the Bridgestone Alenza 001 rated 53%

while driving a BMW X3m40i

Driving on a combination of roads for 25000 spirited miles

The Bridgestone Alenza RFT in 245/40R21 front and 275/35R21 rear is a very average tyre. It’s okay but not great. Grip is acceptable in dry conditions, but in the wet it can slip when pushed, although the AWD system helps manage it. Ride comfort is harsh, with noticeable thumping over bumps and poor handling of rough roads. This is typical of run-flats, but still disappointing at this price point. Feedback and progression near the grip limit are minimal, making spirited driving feel numb.

Wear has been reasonable. After around 40,000 km, the fronts have about 5 mm of tread left while the rears are down to 2 mm. The front tyres show noticeable outer edge wear, likely from SUV weight transfer during cornering. Running higher-than-recommended front pressures helps mitigate this.

Overall, it’s an expensive tyre with no standout qualities. The limited run-flat alternatives in this size make that more frustrating.
