Summarize this article in one sentence.
When the front tire is done, move on to the rear tire. Line up the strap with the rear tire, on either side, and tie it to the trailer at this point. If the trailer has hooks or other tie-down attachments, secure the strap to this point. Pull the strap towards the tire and loop it through. Wrap the tire with one complete rotation, then pull the strap towards the other side of the trailer. Make sure you only wrap the strap around the tire, not around any spokes. Tie the ratchet strap to the opposite side of the trailer. Then loop the strap through the ratchet. Crank it to tighten the strap, and continue until it pulls taut. Flailing straps can damage your car and motorcycle if you drive at high speeds. Finish the job by securing all the ends. Either tie them to the trailer, or loop them around the tightened strap portion and tie a knot. Monitor the straps as you drive. Glance through your rearview mirror to see if any have come loose, and pull over to tie them back down if they have.

Summary:
Tie a strap parallel with the rear tire. Wrap the strap around the rear tire. Attach the strap to a ratchet strap on the opposite side of the trailer. Tie down the loose strap ends so they don’t flail.
