Question about stabilizing 40' trailer with cement clocks

I just finished doing the exact same thing to our new 40 footer.

What I did after I had the frame on the piers was to use a Camco stabilizer jack under each shakle of each wheel axel. that will keep the axels exactly in the same place and then just forget about the wheels. As the tires lose air pressure over time, they will have no affect on the rest of your system.
Once my warrantee is off the trailer, I will probably leave the slides out permanently and block them also
