Tire installation

[boisesmith]

Just received my new tires and plan to take the old ones off the trailer to have the new ones mounted. Thinking 2 at a time. Plan on using the level up system to raise the trailer. Question is, should I have the tow vehicle attached?

I did all 4 on mine no issues.

No need to involve the truck. IT just places undo pressure on the pin box. As 77Cruyiser wrote, take all 4 at once.
