Venting tires on aluminum beadlocks

[Natedog]

Eh, I"m definitely in the vent camp use a leather punch to do it cleanly and not too large of holes. I like single stage foams and they work great when sized appropriately for the tires.

I don't vent my tires. I squeeze them when i build them that gives them a softer and more compliant feel without letting mud in the wheels.

It's not just the water that's an issue for me, open cell foam will and do act like a sponge soaking up all that animal piss, shit and other biological matter to rot and fester away until I toss them and buy more, no thanks!

I'm gonna go play with my toy now, cheers!

SO YOU DON’T use single stage..... that’s the point, use the PROPER FOAM for where you run and no rotting or any such nonsense. Did you READ Eddies information??

And what do you do when you live in a country where CI foams are hardly stocked and its stupid expensive to import?
Make a plan and use what you got.

ps: I run store-bought now.

Thats what I’m doing till CI’s gets introduced properly over here. Packaging closed cell and weather stripping... With stock foams on top. Works thus far.

Couldn't agree more.

I don't vent my crawler tires. Mud and water ruin open cell foams no matter what some people claim. Water certainly changes the characteristics of open cell foam and that's an immediate consequence. I've tried undersized, closed cell foams with vented tires and I wasn't a fan at all. I'll stick to high quality, non-vented tires and rarely is traction the issue the holds me back.

Again, tire venting or not is a personal choice. No one can tell you which is better for you, your driving style, the terrain you drive on or your preference. I get really tired of people who insist that you have to do it their way or you're doing it wrong. The FACT is there is NO wrong way, do what YOU want and what works best for YOU!

You don't agree with me and my experiences?! You can't possibly be correct!

Don't ya just love that attitude?

Unfortunately, it's just the times we're living in Jato.

I DO run single stage, I just use the ones that came with my tires since I am running them non vented, didn't see the need to spend $40 on pieces of foam.

I have read it, not entirely sure what it has to do why I don't run vented tires with open cell foam though.

At the end of the day, I don't care if you run your toys, ups, crawlers with vented tires or not, nor do I care if the OP does.

I was merely just stating MY opinion and experiences with running vented tires, to me it was gross and a pain in the ass, you don't have to agree, you don't have to accept it, you don't have to do anything, accept maybe enjoy your toy, ups, crawler.

100% agree Mike and cited same above. If the tire can’t “breathe”, it can’t conform and displace. And to the 1:1 comparisons, there’s a reason guys air down to 8-10lbs psi when they hit the trail. Venting a scale crawler tire is effectively the same thing. It’s not like you’re commuting with it!

I use CI foams, and don’t apologize.
I won’t waste money, quality lasts.

Sorry I just cant let that statement stand

Well whats this




and this



Understand we aren't arguing that venting isn't the preferred method, just that non vented isn't as bad as some make it out to be.



Whens the last time you venting folks ran a non vented tire? do you have any recent experience with tires besides rock hard RTR tires?

Its the 4.75" version of the RC4WD MT/R's, Crawler innovations Lil nova comp cut 4.5" foams, soft up front and medium in the rear. I cut the foams down to narrow them, 30mm overall for the outer foams and I took 4.75mm off each side of the inner foams to keep them symmetrical. I just cut them down to a size that was no bigger than the inside of the tire. I have a jig modeled that can be 3d printed so you can use a fine toothed Japanese hand saw to cut the foams down. I could clean this model up and upload it if you've got a printer, let me know.

Nice! Thanks for the info and the offer.

I got the 4.19s so I'll have to tweak it a bit, but all that info is a damn good starting place, thanks alot!

Fair enough Humboldt - I may have gotten caught up in what is “better”. I have indeed tried non-vented in the past. Most recently a year ago. Same tire, same foam, same rig, same wheels, same day, same course, blah, blah, blah. My experience with this test was enough to convince me once and for all that vented tires perform better. The tire is better capable of conforming and displacing to the contours of the terrain. I guess my point is, ALL other things being equal - same tire, same foam, same rig, same course, same day, a vented tire is going to perform better.

I can understand some of the logic regarding water and foams, but people are deluding themselves if they think their un-vented tire is completely sealed on the rim. It’s not a water tight system just because the tires are not vented. Water resistant - meh, i’ll give ya that. Water tight? No.

Thank You! I ran non vented once..... and bounced everywhere, then all the air was lost on one..... gripped well, but couldn’t control where we were going. I listen to Eddie.
