Sauber's Felipe Nasr calls for harder tyres in Formula 1 from 2017
Sauber driver Felipe Nasr has called on Formula 1 tyre supplier Pirelli to ensure its 2017-spec tyres allow a driver to push more during a grand prix

Nasr feels the recent Russian Grand Prix offered a taster of what could be in F1 if Pirelli opted to make slightly harder-wearing tyres.
Although for the majority the race at the Sochi Autodrom was only one stop, Nasr claims he enjoyed the opportunity of pushing throughout on both compounds - the soft and super-soft.
With Pirelli's tyres to be wider front and rear, offering more grip and helping to reduce lap times, the Brazilian feels there is also the chance to increase the durability.
"Russia was different to other tracks. It was intense. You were pushing from lap one to the end. There was no tyre saving," said Nasr.
"That's why you saw more cases of wear in the whole car - brakes, engine - the drivers just putting it to the limit. I enjoyed that. It was really good fun.
"So I would be in favour of more grip and having quicker pace throughout the race so you could push.
"If there is degradation in the race then it requires a bit more intelligence, but to be able to push more, then I would like it to go in that direction.
"Of course the idea of managing tyres a little is a good thing, it's nice to have."
NASR TO MULL OVER BRAKE SITUATION IN AUSTIN
Tyres should not be an issue for this weekend's United States Grand Prix at the Circuit of the Americas in Austin, where the soft and medium compounds are to be used, and with the likelihood a two-stop race should unfold.
Instead, of greater concern for Nasr is which brake manufacturer to use as this season he has flitted between Brembo and Carbon Industrie.
Nasr has suggested while Carbon Industrie are more reliable, he actually prefers Brembo.
"I raced with the CI (Carbon Industrie) in Russia because every time we go to a track that is high energy in braking, like Sochi, we've learned from past events we have to go for them," added Nasr.
"Brembo do work if we have the right cooling, but with the package we have on our car we cannot run more cooling, so that is why we opted to run CI.
