Tyre values
PSI - indicates the pressure at which the manufacturer recommends inflating the tire. 1 atm = 14,7 PSI
TPI (EPI)- tyre fibre density. The higher the TPI value, the more flexible the tire will be.
Kevlar tyre- made of kevlar fibres. The tyre can be folded, so it is more practical when moving or storing. It is characteristic of its lower weight compared to wired ones and higher puncture resistance
Wired tyre- made of wire. It can't be folded like the kevlar one, and it is heavier. Overview of tyre sizes and markings
