Same length? Sometimes. As long as they're long enough to get the tire fully on the stack, that's good. Sometimes they're pieces I cut for ramp blocks sometimes random lumber, sometimes they split and then start the next campfire!
I found bigger truck tires seem to be just big enough to drive up on stair stepped 2x material without kicking them out, if they're all shoved up against the tire. Wouldn't work with smaller diameter wheels like on my trailers, but leftover 5/4 decking (1" thick) works the same under smaller dia wheels.
I must be hard of understanding. If I stack up 3 2X 12s all a foot long, I would think the tire would push top off instead of climbing. OTOH, put a 10 inch on top a 12 inch on top of a 14 inch, likely will walk up with no trouble. Even with my 13 inch trailer tires.
