SAKHIR, Bahrain -- Strategy at the Bahrain Grand Prix is likely to be dictated by rear tyre degradation. Make the super-softs last and drivers are looking at a standard one-stop. Treat the rear tyres badly and they'll be heading for a two-stop. Once again, the gap in performance between the soft tyre and the medium makes the medium tyre useless in the race this weekend, so all strategy permutations are based around a combination of super-soft and soft.
