I picked up a riding lawn mower that has severe cracked sidewalls. instead of spending $250 on new tires, I figured why not try some FlatOut and see if I can save a few bucks.
yeah my follow up video shows it's not worth the hype. it MAY help you in a flat situation by allowing less leakage if you get a thorn in the middle of cutting a yard and get you to the end, BUT it's not a run-flat replacement option IMO.
