Best Tire You Never Heard Of
Following two years of MX and off-road testing, STI introduces Tech 2 PRO high-performance intermediate MX tires. STI tire engineers and professional racers teamed up to produce pro-level tires that combine holeshot-grabbing traction with race-winning durability. These tires are already proving themselves by helping win MX and off-road races.
The new Tech 2 PRO tires use a varied-pitch tread in a pattern with fewer center knobs and a concentrated shoulder formation to maximize performance in both loose and packed terrain conditions. Engineers strategically tuned the PRO’s lightweight carcass for the optimum balance of stiffness and flex. This maximizes the contact patch for best traction, and preserves bump-absorption characteristics, keeping the tires planted for performance.
The newly developed compound helps the tire hook up on hard-terrain MX conditions, and lets the tire excel in harsh off-road conditions. These new Tech 2 PRO tires provide durability that will be appreciated by top racers at a price trail riders will admire.
- A true intermediate tread pattern that actually excels in both loose and semi-hardpack conditions.
- 4-ply carcass tuned for best balance of stiffness (traction) and flex (bump absorption).
- Long-lasting rubber and tread designed for traction and control in high-performance settings.
