Any review sa Koby Tire sealant?
Effective ba sa gulong kotse or pang motor lang?
Thanks
Generally speaking sa lahat ng liquid tire sealant.... Not advisable. Pwede as an emergency last resort. But be ready to clean it up afterwards (baklas gulong, tanggal goma, etc.) Messy sya at kung may internal TPMS ka, might as well say goodbye to it.
Mawawala din sa balance yung gulong at pwedeng mag-corrode yung rim in the long term.
Scotty Kilmer says it kept his tire inflated for 5 years :mrgreen:

Comparative review by Project Farm:

Very solid test. He punctured all four tires on a Suburban and fixed each with a different product. Everything actually worked well except for the original Fix-A-Flat.
Followed up with corrosion testing, and a second test with a bigger puncture.
Also it seems like you'll need to have a tire inflator handy if you're going to use these products in the wild. By themselves you'll probably end up with an underinflated tire.

He's sort of an oddball... can't take him seriously sometimes. He offers more opinion than actual scientific fact, so I watch his videos with a grain of salt.
BTT: I recommend against using these types of tire sealants. Keep one in the car if you want for when you absolutely need it, but just use the spare if it can be helped.
Yeah, he rambles quite a bit.
This guy is more systematic.

Edit: Spoke too soon. Dr. Kamiya already posted a video of this guy.
For the most part, he's ok. Except for the way he tests the film strengths of motor oils using the Reichert Wear Test or equivalent machine and then measure the wear scars on bearing surfaces. This has been debunked by another YT creator, The Motor Oil Geek. Suffice to say, that machine is primarily used to measure gear oil and grease. There is nothing inside an engine that is accurately represented by this test method.
This is that video:
But Project Farm's other tests like on tools and such, they're great reference.

Kung walang spare tire, invest on a Inflator kaysa sa sealant.
Inflate the flat tire +10 psi than normal, it should last till you find a vulcanisong shop.
Personally, I'd sooner keep a donut spare tire in the trunk than use a tire sealant.
Trust me. I speak from experience. The mess, the gunk that it makes.... if you clean it, para kang naglilinis ng snot. If you leave it for too long, it eats up the rim and corrodes it from the inside out.
Yup, experienced it myself as well.
Maybe we can summarize what's been said (oj88, Dr.Kamiya and glenn_duke): If there's space, spare tire. If none, donut. If none, run flat tires, tire inflator and tire sealant with tire sealant being the last resort; the tire inflator not being mutually exclusive.
Yeah I think the Project Farm video showed that you need a tire inflator either way regardless of having sealant or not. I guess try overinflating first to see if you can make it to a repair shop, then only use the sealant if the tire really isn't holding air.
In the absence of a spare tire I personally prefer the emergency "tusok" style repair kits. Used to keep a set of those around, but only ever got to use it once (which I guess is a good thing).
If you don't have a spare tire, a tire inflator using the socket of the car as power outlet is the best way to go.
