As I mentioned to you in PM...It is going to be off kilter if built the way I did, by about a half inch as you will need one half inch width axle nut to create just enough space for the disk rotor to clear the frame...Any tire bigger than the 1.75 will rub on the right hand side of the frame.I removed the extra nuts and this is what I have right now.
The 1.75 will track correctly, wear evenly etc. but as I have mentioned many times, even something as simple as the air pressure and brand, size and type tire I use are critical to a successful build
