28″ blackwater evolutions tire pressure??

So I stepped up from the stock tires to a set of 28" evolutions. First impression is that these tires are gonna be awesome on the trail and the mud. Havent ridden much yet as I’m just completing all my upgrades. But my question to those of you that have them are what pressure are you running them at. A quick search shows 3-5 pounds on 27" tires. Anyone care to offer some advice. Thanks.
