With everything ready and raring to go for Stefan Grand Prix, the Serbian based outfit have now had to cancel their planned testing session in Portugal this week due to the fact that they are lacking one very important item, tyres!

While they could substitute the Bridgestone tyres used by the other teams on the grid in this year’s Formula One world championship, team boss Zoran Stefanovic explained to Autosport that without the right rubber they would be defeating the purpose of going testing....

"We cannot do the test at the moment and we are still trying to find a solution. We have no tyres and will not test on tyres that are not suitable for the car to go testing at full speed."
