OP if you're that concerned.... go to your local home care store, i.e. Home depot or Lowes.... pick u some 2" hard foam insulation and drive on them.
The 2" may seem high, however they will climb it and the rears will chew up the first 6" and make a small ramp
good for lowered cars to place the jack under too
That's what did and still do. I repeated the rear shredding twice so I can use a pair in the front too. much easier to climb than wood. You tire catches 100%. will never spit it out!!
