Popular Post Chris Westland Posted February 21, 2017 Popular Post Share Posted February 21, 2017 (edited) Where the rubber meets the road, it seems, doesn't get enough love here. So I thought I'd start a thread to share opinions about tire pressure, maintenance, etc. (starting with some of my opinions). I find tire pressure to be one of the most important components of handling and ride, and I'm a bit obsessive about it on my EUC's (probably carrying over from motorcycles and bikes). There are three things that make tire pressure a challenge with EUC's: EUC's only have one tire, low pressure has a direct impact on ride, and tire failures are unforgiving EUC's have unique bent valve stems that make it hard to find inner-tubes, and a pain to fill (you just don't want to do it) EUC tire pressure is a bother to check compared to any other vehicle, because the valve stems are hidden in the EUC cavity, and difficult to attach to a pump ... and there are probably other things. The net result is that you want to maintain the tire, fill to pressure and forget it. To that end, I've Slimed (https://www.amazon.com/Slime-10056-Tube-Sealant-oz/dp/B003V9XYNW/ref=sr_1_2?ie=UTF8&qid=1487706156&sr=8-2&keywords=slime+bicycle) both my V8 and Zero. I used about 1/3rd of the bottle on each one. There is no effect whatsoever on the feel of the wheel, and I think it provides a certain security. In Chicago, I can take my bike into any number of convenient shops to buy and install a new inner-tube; but the same shops would just draw a blank with an EUC, and the inner-tubes are hard to find. Best to maintain what you have. I like to keep my tire pressure up at 3 bar (~44 psi). The sidewalls of my V8 and Zero tires both recommend 40-65psi pressure, and the V8 comes from the factory at 2.8 bar (~40psi). So for me 3 bar seems the right pressure, and both wheels feel good at that pressure. It's a real bother to fit a pressure gauge on the valve stem because they are bent against the wheel. I almost never get a seal on my gauge without several tries. So instead, I pumped the wheels up with my Lezyne pump (https://www.amazon.com/Lezyne-Steel-Floor-Drive-Black/dp/B005UND3CY/ref=sr_1_3?ie=UTF8&qid=1487706504&sr=8-3&keywords=lezyne+pump) -- I recommend Lesyzne as the absolute best bike pump on the market -- and then put a Gozens 44psi cap (https://www.amazon.com/gp/product/B01HRIKIY0/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1) on the wheel. That way, I can easily check the pressure at the start of each ride. You do need to buy the Gozens at a particular pressure (BTW, they have bluetooth systems, which I think are a bit of overkill) but you get 4 of the basic caps for $9, so NBD.
