Security Concerns Force Pirelli to Scrap Bahrain Tyre Testing Programme

Pirelli has called off a scheduled wet-weather tyre evaluation session that was set to take place in Bahrain this weekend. The cancellation comes in the wake of Iranian missile strikes affecting the region.

The Italian tyre manufacturer has announced the postponement of its wet-weather tyre testing programme that was due to commence in Bahrain over the coming weekend. The decision to pull the plug on the planned evaluation has been made following missile attacks launched by Iran in the area.
