Has anyone considered drilling a hole into their rc tyres.........why you ask!!!!

[Aitch]

and filling the tyre with expanding foam to stop it ballooning, thinking about how expanding foam works, it sticks to everything within the space it is injected to, anyway i am gonna do it for a bit of fun.

On the carbon inner body shells, wow they are solid, i would say you could put some serious weight on them without them deforming, lastly i am today fabricating some mt10 rival body support and posts in metal,

I shall update with some photos later today. Aitch

I'm not expecting great things from expanding foam....but I won't stop you.

Get some action photos/vids if you can, please.

I'm picturing that plastic pop bottle RC video.

Having worked with expanding foam I think the issues are numerous. How do you get it to cure in the shape you want? Balance might be difficult.

So let's theorize that it's cured round, how much impact with they take before they crumble?

I genuinely hope you succeed so we can see what happens

Why exactly do you want to try the expanding foam in your tires? You mention ballooning, but that can be mitigated somewhat with diff fluid tuning. There are belted tires available as well that are not prone to ballooning.
With all the messin with expanding foam I have done (high end 2 part for boats, spray foam, can foam, you name it...), seems like after the first run, it will be completely deformed and crushed.

nothin wrong with trying though, as they say, necessity is the mother of invention. Maybe you are on to something?

Have you ever thought about why manufacturers don't fill their tires full of expanding foam before they sell the kits?
I'll try to explain the best I can as to why it's not a great idea.
Two things actually will happen, #1 you will ruin a set of wheels and tires.
#2 the amount of surface of the tire will remain the same under load as well as just sitting there, another
words, you will seriously lose grip because the amount of tire making contact to the surface you are running won't change,
if that makes sense.
You will lose much needed grip at high speeds.
During heavy acceleration and braking, you won't gain any needed surface for better grip.

That makes sense because it won't conform to the surface, like PowerWheels tires.

Not to mention you will also lose a bit of shock abortion.

Hopefully he aborts this idea.

Hopefully he aborts this idea.

Or at least gets the whole process on video...

 

[Tunedfrog]

My suggestion would be if the OP still wants to try this then I highly recommend a good supply of parts cus she gonna bounce and slide all over the place.

 

[Ritz413]

All the possible outcomes so far are based on the injection actually going well. How do you get the same amount of foam in each tire....what if the expansion has air gaps....and it's expanding foam...might just permanently balloon the tires. But if they wanna try it, I am willing to watch.

 

[RudyF6]

I'd almost bet that if you try it the tires won't stay round.

As long as they're only flat on the bottom...am I right?!

I wanted to see a rock hard solid body in action with foamy stuff filled tires.

 

[Tunedfrog]

@Aitch we appreciate the question and we're certainly not laughing at you so please don't take it that way but
in reality, it isn't a good idea at all. You will lose serious stability with the car.
Rock hard tires are going to transfer shock to the next weakest point and break other parts. The tires and foams supplied helps with shock reduction.

I was in a pinch and used Gorilla Glue. (The water activated foaming kind) to glue back blown tires.

Results were not great. Under 2s it held ok. 3s not so good

Running droop is key for handling. Also greasing the rear diff helps it diffing out
