From Lugz RC:
Tire is designed as a semi directional, one direction will give slightly more forward traction & less side grip or reverse the direction and have slightly more side grip and less forward traction.
Also a great tuning option on the front of the car, before doing set up changes to the vehicle to add or loose steering, try rotating the tires.
This Directions bar tire is designed for optimal traction.
