To chime in on this, this is 100% correct. Your current trucks are 218mm, ideally you want something more than 200mm something similar to a boardnamics, as they offer a 260mm wide version. You’ll need pulleys, a different belt length (which you can calculate at the end), and some wheels! (Duh🤣)
Many people have this exact board with pneumatic, mostly you’ll use 6" tires as to keep the sporty feel. Bigger than that and you’ll lose stability with that deck.
For 6" you have not too many options, one being Haggy Bergmeisters, which are unobtainable for the moment because he was moving to Europe and closed down his store. There are some Janux hubs but are also unobtainable (he went out if business), and cheap AliExpress ones which I don’t recommend.
@Bavioze also was making prototypes that look amazing, maybe he has a spare set?
Note that all these hubs fit 2.8" tires.
This is a very specific categorie, not every tire will fit.
Refer to this thread for tire and hub sizes.
You should do a bit of searching on the forum using the search tool. Once you make up your mind maybe create a WTB thread, as maybe someone is selling what you want!
Hope this answers the question.
Remember use the calculator to help determine what wheel pulley you want as this determines the speed/torque!
