anyone know how to do so?
I would strap to all four wheels, with a towel between the wheel and the strap to prevent any wheel scratches. If you can get to the control arms, they could work as well.
I trailer all the time. I use a winch to load the car because there is only a few inches of clearance on either side and driving it in can be a little scary. Car should be in neutral with parking brake set. I use 10,000 lb axle straps. One through each wheel with some type of towel or cloth to protect rims. Some people cross the rear straps, I'm not sure it really matters. I also place wheel chocks on all four wheels. Tighten down the tie down straps at opposite corners first.
