All-Japan Dirt Trial Tyre Choice: A Real-Data Analysis
Recommended compound by surface condition and how top teams approach the tyre strategy decision
Tyre selection in the All-Japan Dirt Trial Championship is among the highest-impact setup decisions, yet documented public information is almost non-existent. WSJ has systematised 2026 season tyre strategy by surface condition, based on interviews with multiple top teams and collected race data.
Tyres in the All-Japan Dirt Trial Championship divide into two principal families: longitudinal-groove tyres (for gravel and mud) and block-pattern tyres (for harder surfaces and all-round use). The main domestic suppliers are Dunlop, Yokohama, and Toyo, with class-specific tyre regulations in some categories requiring advance verification.
