Round 19 of the 2026 season brings the Formula 1 paddock to the Autodromo Hermanos Rodriguez, and tyre suppliers Pirelli have locked in their compounds for the Mexico City GP weekend. Unlike last year's event, which featured a compound step by using the C2 as the hard option, this time around the C3 has been chosen as the hard compound, paired with the C4 as the medium and the C5 as the soft.
Every driver receives a standard allocation for the weekend: two sets of the white-marked hard tyre, three sets of the yellow-marked medium tyre, and eight sets of the red-marked soft tyre. The green intermediate tyre and blue full wet tyre will also be available if the weather turns. Drivers who fight their way into Q3 in Qualifying unlock an extra set of softs, while Grand Prix rules dictate that every driver must run at least two different slick compounds during a dry race.
There is a massive variable waiting for the teams this time: extensive resurfacing. Pirelli notes that fresh asphalt covers the stretch from Turn 16 to Turn 1 and from Turn 7 to Turn 16, leaving only the first sector mostly untouched. New asphalt usually brings higher grip and lower roughness, but teams will have to gauge the real-world behaviour as soon as track action begins.
Historically, the Autodromo Hermanos Rodriguez has been gentle on rubber thanks to its low-speed corners and low lateral loads. But the thin air strips away aerodynamic downforce, hiking up tyre slip and turning graining into a serious factor to watch. With smooth new asphalt laid down, that dynamic could heavily influence strategies. Track evolution will likely be wild during the opening sessions as well, given how dirty the circuit usually starts before grip ramps up lap after lap.
Strategically, the low severity of the track combined with how these three compounds behave elsewhere points toward a potential one-stop race. Stint extension still matters, especially with the rear axle taking the heaviest beating. Strategy variations will likely come down to driver confidence on a given compound rather than raw tyre life limits. Some teams might lean on softer compounds for extra grip, while others prefer the stability of the Hard.
The soft C5 compound could become a major player. Having shown strong traits on low-severity tracks, it might tempt teams beyond qualifying and into the race itself, widening tactical choices compared to past years. Meanwhile, braking performance needs close monitoring because the altitude cuts aero efficiency and complicates heavy braking zones. The long main straight feeding into Turn 1 raises the threat of lock-ups, particularly early on when grip is at its lowest.
