Norris and Leclerc with less soft tyres than their rivals

McLaren driver Lando Norris and Ferrari racer Charles Leclerc will have less soft tyres for the remainder of the Belgian Grand Prix after having used two sets of C4 rubber in the second practice session.

For this, the 14th round of the season, Pirelli has chosen the same trio of compounds as used for the last two years, namely C2 as P Zero White hard, the C3 as P Zero Yellow medium and the C4 as P Zero Red soft.

As per the sporting regulation, each driver can use a maximum of 13 sets of dry-weather tyres for the full three-day weekend. The allocation of slicks is broken down by compound, so each driver gets two hard sets, three medium sets and eight soft sets.

Interestingly, the majority of the field used a set of medium or hard and a set of soft tyre in the opening session, and replicated this choice in the second session.

McLaren driver Lando Norris and Ferrari racer Charles Leclerc elected to run a set of mediums in Free Practice 1 before switching to the softs. In the second practice, they both went for two sets of red-walled tyres.

It leaves them with two sets of hards and two sets of mediums, but only five sets of softs for the remainder of the Belgian Grand Prix weekend. It could affect their Saturday, but should the final practice take place in wet conditions, their allocation could converge to their rivals' one.

Interestingly, Daniel Ricciardo and Yuki Tsunoda have no more fresh hards, only the mandatory single set of the white-walled rubber which teams are required to carry through into the race.

However, the two RB drivers only completed a single lap on the C2 compound which is a practice that Aston Martin has been doing for a while. This extra preparation lap could help get rid of Pirelli's shiny surface and thus getting them up to temperature quicker following a pit stop, but these tyres also lose their peak grip, that's why most of the teams do not follow this practice.
