I'm glad I did. Took Taco in for first service. Owners manual indicates tire rotation front to back. The rinky dinky dealership did a cross. I'm glad I marked my tires. I called them on it and they said they always do it that way. I showed them the owners manual and had them re-do the rotation. Additionally, they over inflated the tires and the pressures were not consistent. Only reason I went to this dealership is because the next nearest one is an hour away. Now I'm waiting for a survey from them.
