Do I have wrong gravel tires ? Low pressure ones..

Hi guys! Im excited to go on my first adventure. Will be 5 days, 70km/day. Route is 90% road 10% dirt. Took my bike to service, and tires required replacement. Cause of my intended route I selected new tires based on its profile. However, when I arrived home I found out these are lightweight tires for "triathlon". Model: https://www.ereresearch.com/products/ere-tenaci-cc-tlr-black

My previus tires had capacity of holding up to 5 bar of pressure, while the new ones can up to 3.5bar (written in the tire itself). However in the specifications (link above) it says up to 5, Bar, but recomended 4bar.

I'm concerned, as I'll travel a bit heavy cause I'm camping and I don't have high end lightweight equipment.

Picture of the loaded bike attached. Also I weight 86kg.

Please let me know if my concern is valid and what should I do. I searched a bit about this, but couldn't find info, mostly tire reviews good/bad and how to choose tire profiles but not much about pressure.

Thanks guys ❤️
