The ramps on the bed of my truck
The ramps being used on a Freightliner truck
A view of the joints on the ramps
Them ramps while they were being built in my backyard
They are built out of 2x12s. The bottom piece is six feet long. Being five planks thick, they lift the truck up 7.5in. I plan on adding one more piece at the bottom, to give a total lift of nine inches.
For me it was either build the wood ramps or get a pair of OTC truck ramps

I put a joint in the middle for 1) Ease of storage and handling 2)After the truck is up, the rear section can be removed to give access from the side of the truck.
With each step being a foot long, it is really easy to drive up on to the ramp since you can feel each step and I just count to five and then stop. There is no tendency at all for the ramps to slide. No need for rubber or carpet at the bottom of the ramps.
The Freightliner weighs 7 tons at the front axle and I felt perfectly safe under the truck. There doen't seem to be any undue stress on the wood.
