The Time Attack Weapon
The Tri-Ace Formula R1 is the sharpest tool in Tri-Ace's competition range — a semi-slick built for time attack, hillclimb, circuit racing and track days. In 265/35R18, it's engineered for outright pace with heat management to keep grip consistent lap after lap.
Why Choose the Tri-Ace Formula R1?
- Maximum Pace: Tri-Ace's fastest semi-slick, developed for time attack, hillclimb and circuit racing where grip and speed decide results.
- Even Heat Spread: The construction distributes heat evenly through the tread, avoiding localised hot spots and keeping grip consistent.
- Wet/Dry Balance: The pattern balances performance between wet and dry conditions and resists irregular wear.
- Compound Options: Offered in multiple treadwear compounds so racers can match the tyre to their discipline.
