Our Man in the Tropics Posted August 18, 2017 Share Posted August 18, 2017 Hi fellow Thaivisa.com Posters, I searched exhaustively for information on Internet as to recommended Air Pressures for Front, & Rear, respectively, 100/90-12 Tyres of Honda Zoomer X Scooter, but to no avail. The only available manual, as far as I know, is in Thai language ; And, according to my wife, it states : Front ; 29 p.s.i. Rear ; 33 p.s.i. I note that the sidewalls of each tyre, Dunlop brand, that was supplied as Original Equipment from Manufacturer [ Honda ] -- O.E.M. -- state only maximum pressure vis. 36 psi. There are 2 scenarios to consider : 1. Driver only on the scooter 2. Driver with Pillion Passenger on the scooter. With reference to 2. [ above ], I did come across mention by Dunlop or some tyre retailer -- I forget which at this moment -- stating that when carrying pillion passenger both tyres [ or is it only rear ? ] should be pressurized to stated maximum air pressure rating of tyre. Here's hoping for knowledgeable Posters replying with authoritative information. Regards, Our Man in the Tropics Link to comment Share on other sites More sharing options...
ktm jeff Posted August 21, 2017 Share Posted August 21, 2017 Rider only , F 29 , R 33 sounds right. Raise rear to 35 / 36 for pillion. Use your own digital gauge. Check every 2 / 3 weeks. Link to comment Share on other sites More sharing options...
Our Man in the Tropics Posted August 30, 2017 Author Share Posted August 30, 2017 Thanks ktm jeff. Sorry for delay in replying ; I did not sign into the forum since circa 20 August. T I have "Analogue" Air Pressure Gauge only. Also, I wonder ; How accurate are the User pre-set Air Pressure pumps for free Use at PTT garages ?

ktm jeff Posted August 30, 2017 Share Posted August 30, 2017 Hi. If your analogue gauge is accurate ( try checking readings against another gauge ) , then its fine. LCD ones are smaller and can be easier to use on smaller scooter wheels. Garage gauges , if dropped , may be out . Could be said they are better than nothing though. Shell garages often have good gauges. Link to comment Share on other sites More sharing options...
