GT-α 2026
Flagship semi-slick. Built for the apex.
The GT-α 2026 is RubberCraft's flagship semi-slick — a refined dual-rib pattern engineered for fast warm-up and championship-grade grip across a wide operating window. Reinforced shoulder blocks resist deformation under high-g cornering while the silica-rich compound holds longer, lap after lap. The tyre of choice for time-attack drivers and weekend warriors chasing every tenth.
