Default Venting tires on aluminum beadlocks

I've been having a hard time getting much information on this topic.

I have a TRX4 and the wife picked up a set of beadlocks. I used a heat gun and got the tires off the factory wheels and installed on the beadlocks.....However, there are no wholes drilled in the beadlocks.

Should I vent the tires? I have a 4mm leather punch that I use on all my 1/8th scale stuff, but wasn't sure if crawler tires should be purposely punctured or not.

I have a drill press and could try to drill holes into the wheels but with the beadlock ring going over top of the inner wheel pieces I'm not sure how air would get through, I feel like I'd have to drill a hole and line it up during installation.

What do you all do?

Just curious, but, what brand are the beadlocks? Using SSD & Vanquish as examples, SSD uses plastic center rings, so they're easy to drill, and Vanquish has "pre-tapped" points from their rings, showing where to drill

Venting is not required but it can improve traction. You can vent the wheel or the tire, personally I vent the tire.

Depending on the foams and whether you run through water or not you may or may not want to vent. A closed cell foam is waterproof but open cells are not. People will say that you can get the water out of the foam if you vent the tire and spin the tires up... but I disagree with that as I've had sets that were wet after trying that and letting it sit up high (to dry out) for weeks. Only way to completely dry them out is to disassemble them which can be a huge chore depending on the wheels.

I use a old soldering iron to melt 1/8" holes in the tire, usually 2 on opposite sides or 3 (equally spaced). 4mm seems just a touch on the large side but it may be okay.

I'd try em without venting first, it's much easier to add holes then it is to remove them.

You could also cover any holes you make with Gorilla tape etc. if you know it's gonna be a wet run.

Where I live there is ALWAYS water, I personally never vent for that reason.

So your tires are always "Inflated" essentially since there is no way for air to move in and out?

I believe she got then on Amazon so I'm sure they are cheap CN crap. She is a little too practical to dump $100 on beadlocks for a toy car.

Not a "toy". Kids play with "toys"...adults play with "powered scale vehicles".

Your best bet is to vent your tires. Your leather punch will work perfect. I do 2 holes 180 opposite each other on the tire, along the centerline and between treads. To allow your foams to work, you have to allow the tire to breathe. CI foams has some good posts on this here on the forums, at his website.

Lol, trust me. I've been through that a thousand times with her. She hates all hobbies and sees them as a gigantic waste of money.

She calls them toys to bother me.....it usually works.

Sounds like one of our other chauffeurs, and his live-in ex-wife.

I'm not adding air to my tires, no they aren't inflated.

I'd say its more like running a tire with low PSI as even a non vented tire has some "crush" to it.

If you could read the tire pressure or lack there of with a standard tire gauge, it would read 0 psi.

Literally not adding any air pressure to the tire, it's the exact same air pressure as the atmosphere surrounding it when mounted.

I agree, I wasn't trying to correct you. You're right it is running 0 PSI essentially, but since its an RC the comparison to a 1:1 tire would be closer to an aired down tire. Thats all I meant.


I think people underestimate how good crawler tires can work non vented, sure there's some room to improve but they still work damn good (provided they are actually good tires to begin with).

The only tires I have that are vented are the stock glued tires on plastic wheels. None of my bead lock wheels are vented and I have never felt a need to vent them. But do what works best for your driving style.

Same. Non vented tires.
I like to run with CI closed cell foam in a smaller diameter. This way I have an air gap which let the tire work really well and still have good side hill stability.
Maybe not as good as vented, but more then good enough for my runs and no mess when driving through mud and water.

I run non vented on my heavy d90. It works much better for me. Its all dependent on your setup though. It doesn’t work on any of my other rigs because they weigh almost nothing compared to the d90. The rigs seem too bouncy then.

Well I appreciate all the feedback. I'm still running on the factory TRX4 foams but I have done the "Star" modification where I have cut the foams. They seem to be ok un-vented but I am going to my first crawler course in a few days and wanted to make sure they were going to be ok. Should be entertaining.

Color me stupid then. I started in go fast trucks, non vented and taped to stop tire growth at speed..(pizza Cutter effect) found that belted tires and good foams didnt grow, good foams are the "air" in our tires. yes you need to vent], PLEASE stop the water nonsense. Eddie at CI has an entire article on WHY and WHAT......simply put two stage foams are for our crawlers, single stage or none is for toys.


side note, I live in the Everglades..........A bit of water here!
