5" wheels

[Gregor]

Raise one of the outside wheels 1/8". Drill a clearance hole in the current existing holes for your outside wheels, then rivet or bolt a new piece of metal overtop, which the axle hole raised.

I know 610 did this last year, ask them for a few pictures.

You could also attach a length of tread material (e.g. wedgetop or roughtop) to the outer rim of your center wheels. You really only need a very small bit of extra diameter in order to reduce wheel scrub while turning. Alternatively, you might try removing a bit of tread from the corner wheels to get the same effect.

The slight difference in diameters will give you some wheel scrub when driving normally, and you might see some tread wear because of it.

Try skyway wheels. (Remember them?) They used to be in the KoP and they sell a 5inch wheel.

Similar to this^

Drill the hold 1/8" higher. Insert "shims" under axle. The shims we have used were steel sheet metal.

If you have bolts as axles, (not live axles) you could re-drill the 3/8" holes with 1/2"(offset higher 1/8") and change wheel bearings to 1/2".

Or check a few 4" wheel brands, like the vex or Andymark traction and see if they are slightly bigger or smaller.
