Mark Webber on Saturday said he is not worried about running out of useable tyres in Belgium.
Earlier at Spa-Francorchamps, where wet and changeable weather has featured regularly so far this weekend, Bridgestone admitted it is worried about drivers running out of rain tyres.
Each car is restricted to 3 sets of extreme wet compounds and 4 intermediates for the entire weekend, and so far those tyres have only been lasting a few laps before graining and degrading.
But after securing pole on Saturday, championship leader Webber played down the situation.
"I think we should be fine for tomorrow’s grand prix," he said. "Maybe they will have to make a few more for next week but they should be able to do that."
Renault’s Robert Kubica agreed, explaining that the mostly dry qualifying session had helped drivers to preserve their allocations of wet tyres.
"If qualifying had been wet and tomorrow it’s raining then we might be in trouble but it should be ok," said the Pole.
