Those are supposed to be Condition 4 rims...... All Mountain... fairly beefy rims, but 32 spokes would be better.

I'm goin to estimate those rims have a 120kg limit. WTB doesn't say.
If it was me...I would check to make sure all the spoke tension was even. If you can't do yourself... take to somebody that knows WTF they are doing....not somebody that will just tighten them up.
I've bought wheels that were machine made, and although they were true, the spoke tension was all over the place. Usually the wheels that come on the bike are machine made.
Then ride lightly..... I am 14 stone
