Wheel cribs and race ramps suggestions

Bodyperson said

I'd like to add something but it's probably not that big of a deal for cribbing but... I have years of experience using blocks of wood when doing automobile collision frame repair and those pressure treated pieces of wood with the little claw marks all over them (wolmanized) do not hold up very well. The wood that is selected is soft so it will absorb the preservative and all of those claw marks are incipient cracks waiting to happen.

While I'd agree you probably shouldn't pull some wood out of the dirt pile to build cribs, I still think if you did, it would be more safe than a jack stand that cracks. With a crib, you'd have to have all 16 boards in one crib completely disintegrate to be a problem. One of them won't be a problem. Cracks in boards are a completely different problem than a hidden crack in some cast chunk of mystery metal. With cribs you have to worry about "crushing" the wood. Any decent piece of lumber will be fine.
