Extremely, that tire is going to blow at any moment. Probably the next time they hit a bump at high speed.
Yep, had a car tire look like that once. Blew up on the road not long after.
I was a dumb kid without a lot of driving experience and car knowledge at that time. Learnt a valuable lesson, luckily nothing worse than a flat tire.
Apparently my old Escort had a very misaligned steering-angle which wore the tire out aggressively over time. I remember the steering-wheel shaking heavily at higher speeds before the tire finally gave out.
Not OP, but usually this is the result of people not having money. Tires are absurdly expensive
