Yes, use the "Four-Wheel Drive Lock button". My owners manual states to only turn the TRAC and VCS System off so that you can "Rock" the vehicle should you get stuck in snow or mud. I live in the mountains of NH and we have plenty of hills and get plenty of snow up here. Portions of the road up to my home are about a 9-11% uphill grade. I have not had to turn the TRAC/VSC system off yet. Additionally, I have the same tires that you do.
However, you can experiment both ways regarding the TRAC/VCS System to see which gives you the better performance under those conditions.
Btw, welcome to the Forum.
