ASK THE MECHANIC Ep 11.
Q: Ano po possible cause bakit lagi nafaflat yung tire ko?
A: Eto po Top 5 usual cause ng madalas na flat.
1. Wrong tube size.
kapag malaki po yung size ng tube kaysa sa tire. Nag bubunch up sa loob at madalas po ito naiipit sa rim at tire lining. Kapag masyado naman maliit (skinny) yung tube nag eexpand po itoh (numinipis) at madaling masira. Make sure na bumili ng tamang tube size para sa tire nyo.
2. Wrong tube installation.
Karamihan mali yung pagkalagay ng tube at itoy naiipit sa tire lining. Para maiwansan ang ganitong issue, Inflate nyo po yung tube ng kaunti bago e-tuck in sa tire.
3. Debris on the rim wall
kapag yung butas ay madalas sa rim side area. Check nyo po yung rim wall ng mga debris. Linisin yung rim wall and make sure maayos pagkalagay ng rim tape.
4. Worn out rim tape or DIY rim tape
Need ng palitan kung manipis na rim tape. Yung mga DIY old tube na ginagawang rim tape (or electrical tape). Baka need nyo na din po palitan ng bagong rim tape.
5. Tusok-tusok
Lastly, etoh po usual cause bakit lagi kayo nafflat, kahit bago bili lang ng tube (see video below). Mayroon maliit na tinik na naka stuck sa loob ng rubber. Kadalasan mahirap ito hanapin. P**i run yung finger along the inner part ng tire at pakiramdaman kung meron itong nakatusok. Gumamit ng nipper/twizzers to pull it out.
