Resurfaced Mexico Track Poses Tire Strategy Questions
New asphalt laid on sections between Turns 16-1 and 7-16 at the Mexico City circuit creates major unknowns for grip and roughness ahead of the 2026 Grand Prix. Williams engineers note the changes will influence graining risk, tire warm-up and whether teams target a one-stop or two-stop race with Pirelli's softest compounds.
Track Changes Drive Uncertainty
New asphalt has been laid on the Autodromo Hermanos Rodriguez between Turns 16 and 1, including the main straight, and between Turns 7 and 16 for the 2026 Mexico City Grand Prix. Only the first sector remains largely unchanged. Williams chief trackside engineer Paul Williams identified the roughness and grip levels of these sections as the biggest unknowns of the weekend. A darker surface could also produce larger track temperature swings between sessions.[1]
Pirelli has nominated its softest compounds: C3 as hard, C4 as medium and C5 as soft. This selection is one step softer on the hard compound than in 2025.[2]
Strategy Implications
The resurfacing adds uncertainty to both qualifying tire preparation and race strategy. Williams expects the race to be a two-stop on medium and soft compounds. More severe /glossary/graining could bring the hard tire into play, while lower /glossary/tire-degradation could favor a one-stop approach. Friday running will clarify the realistic scenarios.[1] [3]
Tire warm-up remains notoriously difficult at altitude. Teams may vary their run plans, with aggressive out-laps and possible build laps required. Finding the right preparation profile could be worth several tenths in qualifying.[1]
