Yes I have a legit kart it's a ultramax I put a new predator ghost motor on it I put the castor and camber back to neutral as I could and slid rear axle over and moved everything to the right to be more even because on our homemade track were not doing a ovalHave you got actual racing go kart hubs?
So a 10in wide wheel for a 6in tire and 6in wide wheel for a 4.5 tireIf you also have right hand turns you don't need three of anything. 10 inch rears and 6 inch fronts should serve you well.
I'm looking at the wheel sizes on douglas website what does the "n" mean on their wheel size sheet^ IF that.
General rule is 1" wider on wheel than tire for pavement set-ups, but when you go on loose dirt backyard tracks, it can be advantageous to stand the tire up taller (narrower wheel) and gain sidebite. A lot is determined by how much grip the track creates (loose dirt vs moist compacted clay, etc.)
That being said, 5" fronts and 6 1/2" rears would be "normal" if you can call it that.
