So I just got my pneumatics set up on some 3D printed hubs (PETG printed hot, no cooling fan, many walls, they are basically solid PETG). They feel great! I tried searching around a few times over the past few weeks and haven’t found any true direct/clear answers about this… I am a urethane skater born and raised and never even really delt with pumping bike tires so please don’t crucify me if these questions have obvious answers, cause it’s not obvious to me… lol.
Although I love the ride… I want to mess around with different PSI, and I am curious what is the most common recommended PSI? Also, what is a safe range for the 6x2in pneumatics? They say 70psi max on them, but this seems really high, as even 42psi feels pretty hard… I expected pneumatics to be even softer than this. Additionally, at 42psi the 6x2s take on a fairly rounded shape compared to their airless square-like contour. Is it safe to run these things maybe at like 20, or 30 psi instead? Besides some decreased fuel efficiency, are there any other dangers/downsides to doing this?
Finally, how about balancing? I know this is a thing, but is it usually necessary to balance your wheels? I notice mine wobble a bit, and I can play around with them a bit to get them to run more true, which helps a bit… But even if I just pop the tires on the hubs, air them up, let them be quite wobbly, the ride even up to 30mph feels smooth and without vibration… So, if the tires don’t exactly spin true unweighted but rode great otherwise, is this even an issue? Or should I shoot for having my tires spin perfectly true without vibration even when I’m just holding it off the ground?
Thanks for the help guys…
