I am not always sure about what he was thinking. or I was not always sure about what he is thinking.?

I am not always sure about what he was thinking. vs I was not always sure about what he is thinking.

The correct phrase is "I am not always sure about what he was thinking." The use of the past tense "was thinking" is appropriate because it matches the past tense of the main verb "am not." This construction is commonly used in English to express uncertainty about someone's thoughts in the past.
