Tyres, F1 points + car set-up: Your Questions Answered by Bernie Collins + Lawrence Barretto

Why do F1 winners get 25 points? Why do tyre-smoking lock-ups happen? Why do F1 cars change for every race? This week on Formula Why we're answering some of the questions you've sent in to [e-mail] so far. Christian Hewgill and Katie Osborne are joined by former Aston Martin Head of Strategy Bernie Collins and F1 Correspondent and Presenter Lawrence Barretto to explore the whys, the hows and the whats. Along the way we learn why F1 cars haven't always had four wheels, why tyre warmers aren't just for warming tyres and why Lawrence takes an extra suitcase to every Grand Prix.

Got a question about how F1 works? We'd love to hear it. Write it or record it as a voice note, then send it to [e-mail] and we'll include it in a future episode.
