8.5"x2" Pneumatic Scooter Tire (M365 size)
Izcelsme
Mantots no oriģinālā Xiaomi Mi M365 — pietiekami mazs, lai skūteris būtu salokāms un viegls, pietiekami liels, lai tiktu galā ar tipisku pilsētas segumu. Sākotnēji Xiaomi + CST sadarbība; tagad atvērts nozares standarts. 8,5 collas bija kompromiss: mazāks par velosipēda riepām (tāpēc skūteris ir pārnēsājams un viegls), lielāks par 6,5" hoverboard riepām (tāpēc tas tiek galā ar bruģakmeni un apmales malām, nezaudējot stabilitāti). 2" platums tika izvēlēts stabilitātes dēļ bez pārmērīga svara. Segway/Ninebot KickScooter (izmantoja 8" bezgaisa riepas), dažādi pedelec skūteri ar 10"+ riepām. 10" bezgumijas (Ninebot Max, Xiaomi Mi 4 Pro), 11" bezgumijas (Apollo, Mantis premium skūteri)
Verdikts
- Universal cross-brand standard — same 8.5"x2" (50-134) fits the entire M365 clone ecosystem plus VSETT/Zero/Inokim 8.5" scooters, so spare parts are cheap and everywhere
- Widest aftermarket variety of any scooter size — pneumatic, tubeless self-sealing, slime, solid, honeycomb, winter and off-road all available in one size
- Schrader (car-tire) valve means any bicycle floor pump, electric pump or petrol-station compressor fills it
- Pneumatic ride quality is the best entry-level option for absorbing cobblestone vibration in Baltic old towns
- Pneumatic versions puncture readily on Baltic cobblestone and broken glass — typically 1-3 flats/year for a daily commuter
- Rear (motor) wheel replacement is genuinely hard (8/10) — the hub motor casing must be split, easy to nick the cable or strip a screw
- Solid airless variants are harsh enough on granite paving to cause wrist soreness and loosen scooter screws — strongly discouraged for cobblestone cities
- Short lifespan vs larger sizes (1000-3000 km pneumatic vs 3000-6000 km on 10" tires) and pressure must be checked every ~2 weeks
