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?
Not OP, but usually this is the result of people not having money. Tires are absurdly expensive
Or trying to drive to the shop instead of getting a tow.
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.
Only when driving.
pumps 100psi into it while in the garage
I only do bar.
But I guess tire go boom?
Yes, in other units that's 203.6 "Hg, or 6.8 atm.
Yes. Replace your rear tire immediately.
Also, have you considered riding somewhere that isn't straight? You've got no meat in the middle, but you've got nice, fat, juicy chicken strips on the sides.
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.
Like the Castro or Boystown?
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!!
Looks good for at least another couple of hundred yards.
Into the cemetery? Very efficient.
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.
Is that true?
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?
Tell you friend he has a death wish
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.
Ironically this is called a chicken strip.
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.
Incredibly so. Not only is their basically no traction, the tire will be unbalanced now and could vibrate causing loss of control, and it could also catastrophically fail at speed almost certainly causing loss of control.
To shreds you sayβ¦
Nah you are good. Tires a solid all the way through, this is just the protective coating.
it is going to pop soon.
Welp, may as well do some burnouts since you need a new rear tire anyway.
Only if you ride it.
Use both brakes, kiddies.
That tire has an elevated risk of spontaneous de-installation.
It's quite dangerous, yes
Is this an American asking that question?
Not possible, in America, a new tire will always be less expensive than a possible trip to the ER.
Thatβs a little too rough for my liking. I would sand it down.
That actually looks like when I split my shorts over at my brother's
It'll buff out
Yes.
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.
Yes. Replace tire plz.
I see a tyre and I want it painted black...
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.
