Do I rotate my tires front straight
back or front to opposite side
Directional tires: straight front to back. Non directional tires: the drive tires go straight to the front or back, the non drive tires criss cross to the front or back. Directional tires will often have an ARROW on the sidewall pointing tire rotation direction, these tires have a tread pattern meant to roll in one direction only. Google for how to's on tire rotating and how to determine direction vs. non directional tires.
