On another RV forum: This fall I watched a tech from Love's dismount and mount a new tire on a truck at the I90 rest stop near Wasta, South Dakota. It was an inside dual tire. The tech used technique over brute force. A few of things stood out:
1. A tire tool was used to lever the wheels off and back on the studs.
2. Conventional tire irons were used. Nothing special.
3. A 5 gallon bead seater (air tank) was used.
4. Final torque on the lug nuts was done with a torque wrench.
and one more thing...
Both the truck driver and Love's tech were female.
