Description

Today we will make our own 1-10 scale RC truck tires using a 3d printed mold and 2 part silicone rubber.

Mix 170 grams silicone per mold. Hold the center section together with a rubber band. I used hot glue to secure the funnel to the mold top. Using mold release might help with separating the mold, though I haven't seen much improvement with it.

You can watch the instructional video here. This is for 1/14 tire molds but the process is the same.

hello can you make 2.2?

The designer has replied

@BuildItBetter

I might if there is enough demand. I don't run 2.2 so I don't have a pressing use for it.

count me int for 2.2

Replying to @BuildItBetter :

or even 3.8s would be awesome

I love this tire mold form! I had some problems with airbubbles, so I just ad some more airholes a grind out the sign on the upper part of form. I think the problem was that the letters have a sharp edges and as the silicone is a bit thick the airbubbles just stick to those sharp edges. But never mind, its a part of doing something ;-)

That is awesome! Thanks for sharing!

Hello was wondering if its possible to make a street tire for a 2.2 in wheel. width 46.6mm outside diameter 83.5mm something like this, tread design not a big deal what it is.

The designer has replied

@BuildItBetter

What is the specific use application? These silicone tires give excellent grip at the expense of wearing down faster. I think in high speed applications they would wear down too quickly. For crawling over obstacles they are great but I think for racing on the road they would wear out fast.

Replying to @BuildItBetter :

you might be on to something there with some of these rc drag cars... from experience, foam is the best for grip but they chew foams like candy. to find a good compound for grip would be wonderful, even at the expense of burning through them. p.s. love the model

Unfortunately, I had a problem with the inner tube and couldn't print it for the sixth time. Does anyone have a solution that can help me?

Did not make tires yet. I scaled the mold to 1:28 because that is the scale I use now. Really curious how they turn out

The designer has replied

@BuildItBetter

I'd like to know how they turn out as well. It would be great if we can scale them in the slicer and they just work.

Replying to @BuildItBetter :

I ran into the problem that the tires where getting to thin. The inner parts should be less so the walls of the tires stay a bit thicker. But I can't do that since that would change the width of the inner circle witch would make that not fit anymore. To bad. The profile looked really great.

@BuildItBetter

Replying to @Robby_NL :

Oh, that is interesting. I just did the math and it would give a wall of about 1mm. Going from 1:10 to 1:28 is a bit of a jump. I am looking to do some 1:16 scale molds for my kids wpl trucks, That might scale better.

very cool mold! however, I get air pockets at the top of the tire every time. I’m using a vacuum pump to get all the bubbles out prior to pouring but I can’t seem to get it right 🤷🏻‍♂️

The designer has replied

@BuildItBetter

You might try drilling some small (2mm) vent holes in the top over the areas where you are getting air pockets. I think my vent holes are not perfectly at the highest point.

Replying to @BuildItBetter :

I made some modifications to the files with added vent holes and got great success. I ran out of black powder but very happy with the results. Making a few changes to the insert to have a grove inset for the rubber band

Hello. Are the tires made with this mold compatible with beadlock wheels?

The designer has replied

@BuildItBetter

Yes, they should work well with beadlock wheels. They are pretty standard for 1.9 tire dimensions.

@user_993323352

About to print but amazing work. I also want to try it for my SCX6, do you think the scale would work going larger? Thank you a great work again!!

The designer has replied

@BuildItBetter

Thank you! It may scale up fine, I am not sure about how it will fit the rim.

@user_993323352

Replying to @BuildItBetter :

That sounds good enough to try ! If I am able to do it, ill report back! Thank you!

@JSMAKERS15

NICE BUT STIIL HAVE BUBBLE PROBLEM . CAN U PROVIDE STEP FILE I WANT TO DO SOME MODIFICATION. IF THEIR IS A MORE HOLE AROUND THE TIRE AND TOP AND BOTTOM IT EASY TO PASS AIR AND GET CLEAN TIRE

The designer has replied

@BuildItBetter

Sorry, I do not share my original files. I found drilling a few more tiny holes in the top will fix the bubble issues, no need to reprint.

@user_185332188

Can you explain how you designed and made the mold for the tire tread pattern? I’m working on an 85mm diameter tire and want to include an aggressive off-road tread, so I’m interested in your design approach. I could use some help.

The designer has replied

@BuildItBetter

It's not really a simple thing to explain. I designed the tire, then designed two mold halves that covered the tire. I used the tire to cut the shape out of the mold halves. This also gave me the center piece to hollow the tire, I then sliced the center tube into multiple pieces to make removal easier. I used youtube videos a lot to help along the way when I came to a task I wasn't sure how to complete.
