I certainly made parts of this build harder than it needed to be. The easy solution for wheel and tire would have been to grab a 6in rim, and any one of the popular aftermarket OneWheel tires. The hard way was to use the standard 5in GoKart tire for around here (Australia); cheaper tires, more sidewall to flex giving a smoother ride and better carvability. OneWheel GT owners seem to be going to huge lengths to run a 6in tire in place of the OE 6.5in tire, so more tire == better tire?
First wheel/tire I purchased was the one on the right. 130mm rim width, with an 11 x 5.0 - 5 tire (11in outer diameter, 5.0in width, 5in hub diameter). I didn’t own the Pint at the time but knew what tire size they took, hence going for something with a similar size. Later on (mid-way through one of the World’s longest COVID lockdowns) I bought the Pint and quickly realised that the tire/wheel I was designing around was quite a bit slimmer. This was in spite of the tire labeling indicating my tire was half an inch wider than the Pint tire. After riding the Pint I was quite certain I needed a wider tire and then ended up with the one in the middle (11 x 6.5 - 5 on a 180mm wide rim).
Would have preferred a slick tire, but around here you get slicks in 4in wide tires used as front Kart tires or 7.1in for the rear. Wet rear tires, which is what you see here, are the only ones that have a comparable width to OneWheel tires. Hoosier has a few slick options I’d like to try, but shipping costs from the US were pretty extreme.
Annoying buying wheels/tires I didn’t really need, but on the other hand, it’ll be very easy to change wheels so I’m looking forward to trying out both. May even try stretching the 5in wide tire over the 180mm wide hub.
I’ve got two of these sitting around from another incomplete project. It shares the same outer diameter so will technically fit, but has a very different hub setup so would require a bit of work to get it mounted.
Apologies for unit usage, I’m just going by how they label stuff in kart applications (rim width in mm, tire width in inches!!!)
