Never saw this question asked, say your truck has 275/70/18 tires your trailer has 225/75/15 speed rated 65, if you’re truck is doing 65 how fast are your trailer tires going what I am getting on a ti...

Tires speeds are rated for ground speeds, not for rotational velocities (directly). That's why the ratings are expressed in mph rather than rpm. Obviously, for a given tire size, one can convert from one to the other using a simple conversion factor.
This actually makes a lot of sense because the internal centrifugal and/or centripetal forces (depending on your accepted frame of reference) in the tire are greater with the larger diameter at a given rpm anyhow, due to the longer lever arm to the tread.
