BBB Medium wheel question

[Rail Co]

Hello all, I have a quick question about the BBB medium wheels. I noticed many people have made MOCs with them and have been able to make the non-flanged wheel and the flanged wheels (i.e. an 0-6-0) be right next to each other. I am not sure how people did this because my non flanged wheel is the same depth as the flanged wheels. Also, I was wondering how people put traction tires on these wheels.

Thanks!

You can use a combination of Technic bricks to change the spacing. Cale Leiphart did this mock-up:

As for traction tires, you'll probably have to grind them out yourself by use of a Dremel.

If you aren't pulling very heavy loads, you can use this technique to apply "painted-on" traction tires. I used that technique on my Glaskasten, and it ran multiple days at a show pulling a pair of two-axle cars.

Also, beware the crank holes! They are sqrt(2)/2 studs away from the axle, rather than a whole or fractional number.

For the traction I've grooved the wheels to apply an o-ring (read this topic: BBB wheels with rubber O-Ring)

...about the distance between the wheels I've used for my BR80 a technic brick of 1 x 12 with holes:

Thank you all for the help with the traction tires and my question about the wheel spacing I was curious if anyone could explain this:

He has the wheels right up against each other in his MOC.

Thanks

He's modified the wheels by cutting them in half.

Ah, okay thank you.
