McLaren and Mercedes to Test Pirelli Wet Tires in Bahrain 🏁

Published on February 16, 2026 | Translated from Spanish

Pirelli has organized a private rain tire test at the Bahrain circuit. For this session, outside the official calendar, the Italian brand has chosen the McLaren and Mercedes teams. The objective is to collect real data on the behavior of different compounds in wet conditions, key information for defining tire specifications in future Formula 1 seasons.

The Search for Real Data in Controlled Conditions 📊

These tests allow Pirelli to evaluate prototypes and new specifications with current single-seaters, something that is not always possible during the free practice sessions of a Grand Prix with unpredictable rain. In Bahrain, with irrigation systems, different levels of water on the asphalt can be simulated and performance, wear, and water evacuation can be measured precisely. The data from both teams will be used to adjust the compounds.

Testing Rain in the Desert, F1 Logic 🌧️

It has its point that rain is simulated in the middle of the desert to prepare for monsoons at Spa. F1, where the predictable is unpredictable, finds its method: create the problem to then solve it. That said, one thinks about the water bill to wet several kilometers of asphalt and understands why this sport has no budget problems. At least the spectators won't get wet.
