Rino Posted April 5, 2019 Share Posted April 5, 2019 Hi all Was wondering what people use as air pressure on 18XL. Mine: I'm 176cm, 85kg full geared, and 35 psi in the tire. 1 Quote Link to comment Share on other sites More sharing options...
Rywokast Posted April 5, 2019 Share Posted April 5, 2019 35 psi is almost flat.. you would be a lot more likely to get a pinch flat or damage the rim if you nailed a pothole or something.. i like 65 psi @ 54 kg.. i usually run around 65 on all my tires 1 Quote Link to comment Share on other sites More sharing options...
Giovanni Posted April 5, 2019 Share Posted April 5, 2019 (edited) Hi @Rino! I would pump 40 psi or even 44 psi and higher, but pay attention to range of pressure, which is recommended to be pumped, usually it is written on the tire/inner tire or look at its package. It may be a little bit uncomfortable and too wobbly at first, but in general it's more safe for your wheel, there are some risks if you are riding on low pressure: deformation of rim, puncture, inner tire wear because it is "chewed" by rim and others). I would recommend higher pressure especially if you ride in aggressive style and jump on/off curbs. If road condition/surface is bad or you are riding in winter on ice/snow, then low pressure is acceptable (with my weight near 85-90 kg full geared I am not comfortable on pressure lower than 20 psi), but you should ride carefully in this case, no jumps and the lower pressure is in your wheel the higher will be risk of puncture.

It is written 35-45 psi as recommended pressure on ChaoYang tire, which was stock tire installed by default on my KS-18L. Also I feel to twitchy on pressure over 50 psi, but I believe it's a matter of time and skill to adapt. By the way, we measure tire pressure in Atmosphere=Bar≈100 kilopascal here in Eastern Europe, so I need always to convert it in PSI to be on the same page with you) not a problem as I ride also folding bicycle Brompton from Britain and pressure is in PSI there too.

Rywokast Posted April 5, 2019 Share Posted April 5, 2019 eh the recommendations are weird and random lol.. some tires say max 110 some say max 35.. I just do the same approx.. oh lol me too I'm also converting to psi xD I pump to just over 4 bar so that by the time I get the pump off and it lets out a little air it's probably right on 4 bar Quote Link to comment Share on other sites More sharing options...
kasenutty Posted April 5, 2019 Share Posted April 5, 2019 I squeeze the tire with my hand and stop putting air in when it feels just right. Quote Link to comment Share on other sites More sharing options...

I've tried this, but I can't get a good read on what feels right. My method is to blow it up higher than I need it. Then I get on and bounce up and down on the pedals. Too hard is obvious, and too soft is obvious too. Where exactly between these two extremes is right for you, only you can say. let some air out and ride a while. Repeat the process until it feels right for you, not someone else (but heed the safety warnings -snake bite punctures, etc) Edited April 7, 2019 by Smoother 4 1 Quote Link to comment Share on other sites More sharing options...
kasenutty Posted April 6, 2019 Share Posted April 6, 2019 (edited) You only find that feel after overpumping about 74 times and letting some out on your ride with a stick you find on the ground, I do like it kind of soft though Edited April 6, 2019 by kasenutty soft 1 Quote Link to comment Share on other sites More sharing options...

Rino Posted April 7, 2019 Author Share Posted April 7, 2019 I changed to 40 psi now. Feels the same as 35 Quote Link to comment Share on other sites More sharing options...
Joker10 Posted April 7, 2019 Share Posted April 7, 2019 I am 210lb and inflate to 42 psi on the king song 18l for general riding. I have been reinflating when the wheel feels a little sluggish in handling that seems to happen for me at about 35 psi. I used to run the pressure on the ninebot one e+ as high as possible to get as much range as possible, I continued that habit with the 16s not so much for range, but because it just became habit. 1 Quote Link to comment Share on other sites More sharing options...
MacPara Posted April 7, 2019 Share Posted April 7, 2019 37-40psi @ 180lbs Quote Link to comment Share on other sites More sharing options...
Olav Posted April 9, 2019 Share Posted April 9, 2019 I currently have 30 psi, ridingweight of over 101kg, but am considering going for 35-40 psi. As I'm probably doing two long rides this weekend I want to increase my chances of getting there, and home again, without needing to be picked up.

Rywokast Posted April 9, 2019 Share Posted April 9, 2019 it would seem that i am an outlier in preferring max psi in all my euc's lol... more responsive, better range, less chance of damage to rim or tube.. only upside of lower psi is a cushier ride but to me thats not as fun Quote Link to comment Share on other sites More sharing options...
erk1024 Posted April 10, 2019 Share Posted April 10, 2019 (edited) @Rywokast I suspect I'll be joining the high-pressure club shortly. I run 120 psi in my bike tires. Gotta love that low rolling resistance... Edited April 10, 2019 by erk1024 added text 2 Quote Link to comment Share on other sites More sharing options...
