Read the thread. He said the tires at at 5/32. Close enough to worn out , plus the damage. I dont see the economic gain of continuing to run them. Life is valuable. Err on the side of caution.
People from different walks of life have differing options based on their economic status, I suppose. If it comes down to eating or new tires, then I guess run them longer. If you can afford a set of new tires, replace them. I’ve been dirt poor eating out of dumpsters and well off so Ive seen both ends of the spectrum. If you can afford new tires, replace them. Simple. If you can’t, make them last.
