Is that dangerous?

Sure is.

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.
- Why did you drive it like that? And how did you get it like that?

Only when driving.

- I only do bar.
  But I guess tire go boom?

If you have to ask, it probably is.

It's probably due to burnouts.
- The mark observed is from locking up the tire while braking.
  Burnout marks would have it evenly worn and ragged margins, discoloration, chunks missing, blistering, or strips of tire missing along the circumference.
- I was thinking the same thing. Either this person didn't replace their tires in a couple of decades or does insane acceleration/turns/burnouts/stunts.
How are you making me hungry for bike tire??
- Forbidden snacks.
Like the Castro or Boystown?

If you're a registered organ donor don't even worry about it bro. It will provide extra grip

Also, metal is much stronger than rubber. So this is actually safer.
- Motorcycle tires don't use steel belts. These are woven cords showing

Looks good for at least another couple of hundred yards.

Into the cemetery? Very efficient.

This is actually the secret "ejecto seato" button.

How is this not the most upvoted comment? I just do not understand!
On a more serious note, yes, this is extremely dangerous and the rear tire should be replaced before anyone rides this bike.
It's also the "magical slide with a smell of barbecue" button, but you don't know which it will be. Tis a surprise!!

Riding a motorcycle? Extremely.

Get off your high horse not everyone can afford a car.
- I mean they could try that horse you insist the original commenter is sitting on.
- High horses aren’t safe either. The averagest horse is the safest horse.

Eh slap a little Gorilla Tape on there, it'll be fine.

On an unrelated note, have you considered taking out a life insurance policy on your friend there?

Very.

This post is obviously not meant serious.

To the right of the damaged section we can see a thread indicator, so there is maybe around 1 mm thread on the right shoulder. Therefore the centre part was below legal limits.

Before changing tyres, the owner of that bike decided to kill off the old tyre completely by doing a burnout. We can see the flat centre piece all around on the tyre, typical for a burnout.

When changing a motorcycle tire it helps to do a nice burnout before starting. It heats up the tire making it easier to pry off with tire irons.

Tell you friend he has a death wish

- Incorrect, a chicken strip is the unused part of the tire closest to the wall. Meaning the rider has been too "chicken" to lean the bike over far enough to use the full tire.
Yeah, the owner rides a bike. I think that's like number 1 sign someone has a death wish.
Source: me. I have a death wish.

Don't worry. Your loud pipes will save you.

Incredibly so. Not only is there basically no traction, the tire will be unbalanced and could vibrate causing loss of control, and it could also catastrophically fail at speed almost certainly causing loss of control.

Very dangerous. You should change it immediately OP

That tire has an elevated risk of spontaneous de-installation.

It's quite dangerous, yes

To shreds you say…

Use both brakes, kiddies.

Nah tis is but a scratch.

Welp, may as well do some burnouts since you need a new rear tire anyway.

Rubber is just the grippy part of the tire. Not super important.

Nah you are good. Tires a solid all the way through, this is just the protective coating.

Is this an American asking that question?

expired
- Having worked in ERs...nah. People can be pretty damn dumb sometimes.

Only if you ride it.

That’s a little too rough for my liking. I would sand it down.

it is going to pop soon.

I had a cop pull me over for a sideways license plate over my tire. He pointed at it and was almost screaming at me for it . Meanwhile my tire looked like that and he didn't notice or didn't care.

Yes. That’s a piece of gravel from popping

That actually looks like when I split my shorts over at my brother's

Oh it's fine, that's a perfectly healthy tire. Absolutely not going to get the rider killed. Trust me, I'm a complete stranger on the internet.

Yuh

It'll buff out

Yes.

That's the threads holding the tire together, they are embedded in the tire for a reason, if you hit those at speed, it could catastrophically fail, as in perforate and blow.

I see a tyre and I want it painted black...

Yes. Replace tire plz.

Motorcycling is dangerous, what difference does a chicken strip make. Damn. I’m hungry now. Gonna squid through the drive in! Tell mama if I’m not returning I’m either dead or in jail.

Edit: damn, should I have added the /s ?

Well it's a KTM bike, so yes, I'd say it's dangerous

That Duke needs a shop.

Yes, definitely. You need new tires. Do not ride like that.
