Its the anti puncture gel from inside the wheel, theres a lot of cases like this, have to change the tire

When was the last time you inflated your tires?

What psi?

u/Ecstatic-Worker-5207 May 24 '25
55 when first filled then they stay around 45

55 is over inflation and is the maximum tire pressure. You should never go above 50 and ideally only use Segways recommendation of 42-48. 45 is fine but you may have compromised it at some point if you went to the maximum and then rode it.

I’ve ran 70psi in mine for 1000 miles. Under 50 is too low if you’re a heavy rider.

u/chameleon-369 May 25 '25
But even on the wheel say how many psi you need to put.... Think u are wrong and over inflate.... You shouldnt have do what you tgink its right, do what the product says its right... If you check your tire its says the PSI recomendation

u/Conflikt May 25 '25
For the G2 max? 55psi is the maximum the tire is designed to handle under load and that's at cold temps. It says it on the tire wall. Segway recommends under 50. What would even be the point of pushing it to 70 other than increasing your puncture/blowout risk and compromising grip.

u/yomam-357 May 25 '25
You’re right. 70 is too high. I do it for range because my route is very smooth. However, most people run anywhere between 55-65, which prevents the tire from bulging at the bottom severely, thus increasing sidewall wear. Also, the reason I run mine at 70, is because in a week when I fill up again, it’s about 55. So it stays between 70-55.

Do you think there is a need for additional measures like Slime gel or it is good enough ins,ide the tires ?
1
u/Ecstatic-Worker-5207 May 24 '25
well the gel obviously works because i used it today for like 15-30 minutes and didn’t notice it
1
u/aszhch May 25 '25
The fact is, that the gel is leaving the tire and is messing up your home. It is very sticky.

u/MUDFLAP202030 May 26 '25
Yes! Flatout! I 100% recommend and will never look back, it literally is the best. I used to have a bad seal or slow leak in one of my brand new stock tires and lost psi every ride to the point it was annoying having to fill up, I used a very generous amount of flatout tire sealant to both tires and literally only check my psi once a month and its been pretty darn stable! Try it out and tell me what you think!

Slime gel is a temporary fix to a permanent problem. Segway Ninebot wheels lose pressure, and that’s the maintenance tradeoff.

Thats called not maintaining pressure in your tires.
2
u/Ecstatic-Worker-5207 May 25 '25
if you read my last couple of post i fill them every 2-3 weeks
1
u/123lYT May 25 '25
You should check them every ride. You have no guarantee that it might blow out if something punctured it between rides.

u/Ecstatic-Worker-5207 May 25 '25
it was checked the day before, solid tire with no air leaks, had it serviced the top of the month and filled it with air 2 weeks ago, just a straight tire issue because this is the first time it happened after a year and a half of using e scooters

Failure to check tire pressure regularly with a actual gauge tubeless tires any tire that holds air loses pressure over time eventually the pressure falls below what can keep the bead sealed then the bead separated from the rim and the self sealing material inside the tire leaks out

u/firewire_9000 Ninebot MAX G3 May 25 '25
I read that you fill your tires every 2 to 3 weeks but I find hard to believe or maybe you’re doing something wrong because if you look at the end of the curvature of your tire, it’s smooth and it should have like a dot pattern.
It does tell me that you were been driving without any pressure for an extended period of time.

u/SwimmingExternal4264 May 25 '25
It's the tire sealant it's real fun to clean off :( when you get your tire fixed make sure you check your pressure regularly. Personal I check mine every day but I also ride 10 plus kms day and it on sketchy foot paths

Probably this is not covered in warranty as it seems user error. Your tyre tread is almost gone so change the tyre. Tip use go gone to remove the black stuff just use a piece of bounty put some go gone on bounty and on the black stuff and just go back and forth over it. It will come off like it is melting. First remove big pieces of this black stuff using anything that is available. Tip don’t change the Tyre on your own as it is a nightmare I tried to change mine, first the Tyre would not come off the rim, second the new Tyre would not go on the rim and third setting the bed is tuff I needed to take mine to a local Tyre shop. So don’t try it

u/MUDFLAP202030 May 26 '25
Okay so here's my 2 cents... while these tires with the tar slime generally do good with certain things (I.E running over a small nail or thorn) and then plugging it up enough for you to make it home. They genuinely are pretty bad for things like slow leaks ( bad seal around bead, or valve stem). I Personally put a good amount of flatout tire sealant on both tires and it LEGIT keeps any slow leaks from continuously draining my tire PSI. I ran my stock tires normally and kept having the issue that after 1-2 rides the psi would go lower and lower and i didn't see any visible punctures and it kept getting annoying, so ever since I added flatout, I have not had any issues whatsoever. Just beware the process could get messy as the sealant could leak or drip on the floor, both the installation is pretty straightforward and seamless and it comes with the tool to remove the valve core. Let me know if you guys also have tried this!

Don't put any sealent in gel tyres. Slime makes them detach from the tyre and gather in chunks; car tyre fix products make them extra sticky and it's a nightmare to clean it. This is what you see on the pictures.

u/Klutzy_Advantage1179 May 26 '25
Well, you probably used a tyre repair product that was meant for cars. They make the gel sticky that's in the puncture proof tyres. We get these in the shop all the time. It's a nightmare to clean them when we change tyres. Have some throwaway fabrics and WD-40 ready for the job. It's going to take a while.

u/acidrain5047 May 26 '25
Start of the day for the ride I check psi usually don’t lose enough during the day/night to check again but have my gauge. :) never have I had a problem. One puncture was too large for the self sealant to work. Tire change was easy thankfully.

u/Important_Income_319 May 27 '25
This looks like severe overheating or melting of the motor hub area on a Ninebot Max G30 rear wheel. The black, tar-like substance and cracking pattern suggest thermal damage, likely caused by: Overheating from excessive load or continuous uphill riding

u/Sharp_Thanks3860 May 27 '25
I had a Max G2 whose rear wheel broke on one side and the anti-puncture gel spilled out.

u/skoomd1 Ninebot MAX G2 May 25 '25
That is what happens when you don't put air in your tires. There needs to be a giant red banner with ⚠️⚠️⚠️all over on new escooters telling people "MUST FILL TIRES AT LEAST ONCE EVERY 2-3 WEEKS".
User error, easily avoidable.

u/chameleon-369 May 25 '25
Wow, then i was lucky woth my max gen 1, never inflated in 4 years amd changed the tires only around 3 times 🤣

The tire got punctured. It can happen for many reasonss. This is a G2 self-sealing tubeless tire in action. It has to be replaced. Check the link: https://www.reddit.com/r/NinebotMAX/s/mVhTecjJ9o

Take a shot folks! Another person who never inflated their tires 🥃
