What type of wood is strong enough for a car ramp?

@BillRussell

Other answers are correct. the type of wood is not important, what is important is the design.

And to do the design, you need woodworking and engineering skills, as well as the requirements, such as span, height, weight.

And, to be honest, your question indicates that you don’t have those skills. Buy a set of ramps.

When you consider what components make up these structural pieces and the loads they carry it’s somewhat certain that engineering skills makes a big difference.

The local Howard Johnson’s was built on a frame of OSB I-beams that looked like they wouldn’t support a chicken coop floor but it seems to be holding up fine.
