Lego Tires w/HALF a Lego wheelset!
 

I still have to photo this mod, but I was digging through the Lego box and discovered some Lego tires that push about halfway onto the ZZ MT wheels, leaving a big space on the end.

Well I grabbed a Lego Wheel, and cut it down the notch with a hacksaw blade.
Now the space has a Lego wheel filler, while the larger tires get a push out to boot!
(Three more were cut to match in moments.)

The tires simply push onto the ZZMT wheels, however some of the stock wheel is left exposed.
I don't know if that will cost me points or not. :)
(I dunno, pretend it's a brake drum or something...)

The difference with this mod over others I've seen is that I'm not deforming the tire by pushing it on over the center ridge, but using it as a stop for both the ZZ MT wheel and the Lego wheel filler end piece.

The effect on performance is very good.
My Monster Herbie Crawler is lifted higher, and the additional weight of the Lego wheels helps when climbing.

*cough* pics now! *cough*

Sounds cool, what Lego tire set did you end up using?

Here ya go!

The tires are labeled 30.4 x 14

Try this too:

Turn the Lego tire inside-out and cut the ridge out with nippy cutters. Now it will fit almost all the way onto the MT wheel.

Now take that same Lego half wheel and turn it around!

When it's inserted it becomes a disk that's flush with the tire, as well as a means of keeping the tires from tapering towards the end.

This wheelset will be featured on my next crawler: Project: XL1.

Cool, looks like I'm gonna have to go raid some toystores
