Ken...the pic?!

Here's a pic of a project for truck wheels. They're the same Lego tires that WRCracer used on his Humvee, except I couldn't get them to fit over the Z wheels so I converted the Lego rims for the Z. The fronts are yellow and the rears are black. The difference being the yellow ones don't have the slots cut in them. To convert them, all you have to do is drill out the centers to fit the Z's bearing size and spacing, then cut the slots.
I also beveled the front of the battery case to give the larger wheels as tight a turning radius as possible. It actually makes a big difference.
All I need now is a body to suit these things. Any suggestions? I'm thinking the colour scheme could be yellow to black so the rims look thought out rather than just using what I had.

I'll post a real pic of the chassis once I get a hold of that camera again.

Oh, those tires, very cool! I was picturing the old-school super chunky ones. Those ones are also really nice and soft, I've used them on my RCX, they're great!

Nice. How about a pic from the side so we can see how high the wheels sit :)

Black and yellow huh? Sounds like a base for those big black and yellow vehicles used by the Judges in the Judge Dredd movie.. yea, the Stallone one..

Ooh, no ball-diff, no alloy, no scratches on that chassis, looks as squeaky clean as a convent girl.. Madonna excluded *Hail Mary*

What Lego set/kit did they originate from?

That's my son's car (hence, no O-plate). He's pretty rough on it. I don't know why it looks so pristine in the scan. If you look close, the front body mount is broken.
I have to post actual pics later.

Those are tires of similar size, ones I almost bought but wasnt sure of.. but they are not the same tires from the hummer pics (unless he changed them since I last saw it) the other tires are very stretchy and squishy like sponge rubber... and they can be easily turned inside out they are so flexible/soft.

What Lego set/kit did those wheels and tyres originate from?

2002.02.15, 06:28 PM
Mondo, I think they are these:

That's strange, the URL got chopped - anyway go to shop.lego.com and search for "tire" and then they are "Small Tires" for Technic.

Draco, Those are the same tires.

Mini-Z, Good reference site

Mondo, Mini-Z's right, it's under small tires on that site.

Thank isn't strange Mini-Z, I noticed it b4...

don't use [ url ] http://www.urlgoeshere.com/ [ /url ]
use [ url=http://www.itshouldgohere.com/ ] title here [ /url ]

without the spaces ofcourse :)

link (http://shop.lego.com/product.asp?id=%7B2D9345FD%2DB664%2D4BCD%2D9B5D%2D BE3FD26D9C6B%7D) that doesn't seem to work and a pic (attachment)

2002.02.18, 09:34 PM

These are the tires i refer to not being the same ones... Thats what I get for looking at the body in the first few but tires in the last ;) hehe... and only remembered the last photo.

2002.02.19, 01:42 PM
Draconious, do you have the numbers "30.4 x 14" on your tires?

2002.02.19, 02:06 PM
yep, I have 8 of the 30.4 x 14... big and clunky ones... if I find a way to do it some what perfectly, I might machine/lathe/dremel the treads down... hehe.

2002.02.19, 02:16 PM
Any pic of your work with the dremel? (so I don't have to f*** up all of my sons tires, about 30 of them laying everywhere ;) )

2002.02.19, 02:25 PM
I might do it, I have yet to get around to it, again they are not realy my Lego tires.. they belong to nephew who dont realy play with them when he comes over cuz I have the tires hidden ;) hehe... All I realy did so far is cut the inner center line rim out, very sloppily, be carful doing this might cut through tire. And I cut one tread off, pain in the butt...

What I might do, not realy working on that now though, is cut razor off all the tread blocks, at least 90% of each one, then put it on some sorta rotary tool... and sand it off. Basicly I have no clue how I would do it ;)... but they would make nice slicks beign 14mm wide.. wider then the Kyosho Brand rims ;).

Might even be able to modify some rims, by cutting the center line in them.. so they make use of the rim inside the tire less likely to fall off ;). But I will not risk the rims doing it...

here's a pic of the truck wheels compared to some off-set wheels.

Here's the difference in ride height.
A rally conversion would give even more clearance.

2002.03.06, 05:03 PM

Those wheels look nice and rugged. Yup, the improvement in ride height is neat too. I reckon they'd be a great base for a custom Ford F-250, or something similar, perhaps a HUMVEE..
Another great attribute of those wheels is the fact they help keep the spur gear away from the road surface, ideal for those outdoor runs

I wonder how the extra height on the wheel profile will affect acceleration and top speed. Obviously, acceleration will decrease ever so slightly, but the top-speed will improve.

Good catch there Ken, those wheels are nice indeed. Or as Ken once quoted on my (oh no, not another one!) CLK's wheels: Those rims indeed look spiffy badd ol' chapp :D

Thanks Mondo,

I'm running a 6t on an X-Speed. Acceleration is still good.
The 'motor revolutions to distance' ratio is really close to using stock wheels with an 8t. I've been using the '56 ford pickup.

What I need now is wide foams for those other rims I widened.

I know that this thread is old and all, but I have dug up some of these wheels that I am thinking of working over for my Overland. I been trying to work out a simple jig to work out the centers for the bearings/bushings. I will do the notch cuts second to mate to the rears.

Ken Mifune
2005.10.14, 02:00 AM
Yeah, I did it on a drill press. An end mill would've been ideal.
In retrospect, it would have been easier to keep everything centered by drilling the jig and then not move it. Recentering it was a pain.

Geez. This is an old thread.

2005.10.14, 04:02 PM
I about give up on the drilling part as it is hard to get the inside and outside bearings to line up. I was hogging it out with a grinder bit by hand with my dremel.

Good thing I have an extra set of S2000 wheels, this is what I am doing with it. Grafting the s2000 wheel centers onto the lego wheels with the centers cut out. I may post some pictures later, in a new thread. The practical upshot here is I can adjust the offset before I glue it

2005.10.14, 05:53 PM

I been poking around and I think these are them off the Lego Education site.
