This post will bring out the Flat Earthers... The TIRE has the inflation marked on the sidewall. The SCOOT has Nothing to do with inflation. The Manual states pressures for OEM tires. NOT after market. Avons run at 40psi, Chen Shins run at 25, Pirellis run at 38 ect. You have to adjust the pressures to what fits your style too. I have the same tire on both wheels, and run the front at 32, and the rear at 36. The front bites better, and the rear stays in contact better. 38 for both felt like solid rubber.
