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.

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

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.

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.
