On my comp/performance rigs that don't go in water, I vent them on the wheels with 2 holed drilled on the inside, if their dual stages, you've got no choice other than venting the tires, or go unvented.



I think you should do with unvented first, and if you feel like it's negatively effecting your performance, vent them.
Thankyou for all the replies, i appreciate it, looks like this is a sensitive subject I will just avoid water for now till someone invents real waterproof rc wheels with real scale performance. Thanks again for everyone's input

Just enough life in them left to keep the tire from folding over. I tend to not overthink something that simple, itís foam lol.

Yeah, lol that makes since! It was about 2am when I responded, so I missed a thing or two. I personally run non vented without foams and it grips great.

Heres how I see it. Vented with nice dry foams do likely grip the best. However, once those foams are all soaking wet your actually better off with a sealed tire/wheel that still has dry foam in it.

I play in riverbeds frequently and cant stand the truck hauling around heavy water-filled tires with mushy foams inside.

Yeah, people tell me to vent the tires and just hold the truck in the air at WOT to fling the water out. My experience is that the average trail truck doesnt have the wheelbspeed to accomplish this. You get like half the water out and in a few weeks you still have ruined foams.

Well thatís correct for single stage foams.

However the world has Other foams, Two Or Dual (closed cell) stage.... that donít hold water, relying on size and air space for proper grip. Iím in the Everglades.... I never use single stage foams.


Hang up and Drive

I don't vent tyres or wheels.
Pro-Line says don't..

66% do not vent.

That's because your foams are too stiff.

My ALT foams work great in sealed tyres.

I've tried driving on snow, no shrinking.
No ballooning when I go to 100m(330ft)hilltop that is just 10min drive from my place.

I think he meant like a major elevation change. As in a mountain.

Going 1000m(3300ft) higher changes the pressure 10%.
Often it's colder on the mountains so it offsets the tiny pressure change.(1psi/10F)
Not to mention the tyres may not be vented but certainly it's not airtight. The pressure evens out slowly.
Going really high with your 1:1 car, have you ever had problems with tyre pressure and ballooning...

Warning!

If you waterproof your servo and receiver box, they burst open and spill their guts all over the place if you go to higher elevation where unvented tyres start to balloon.
You may also notice that breathing is difficult because of the thin air.
Cooking noodles takes longer because water boils in a lower temperature.

Yeah, maybe second thoughts on taking my rig up an extra 13,800ft

I used to live on the coast so 0ft above sea leval and when i went to tahoe amd crawled at 10000 for above sea leval my tires needed venting cause they were balloons and then back the other way they would suck up creating a flat spot in the tire i only needed to pull one screw to vent them but got to the point were i got tired of doing it and opened up the vents on the wheels my new place is at 3500ft and going from the beach to my house theres no change but from 0to10000ft its a huge difference
I started venting my tires cause.the rim vents would clog up with dirt and would have the balooning and shrinking problems again not a big deal if you dont traval from coast to the top of the sierras i was making the trip every other week for a while enuff to see it as a problem especially with multiple rigs

Yeah, I bet itís fun around Lake Tahoe We drove from Indy to Oakland to Seattle and I wish I wouldíve had my rig with me. We went through the sierras and Rockies, I was so mad I didnít bring it. Iím not going to be going near that 14k ft mark, Thereís good spots at 0-4K

Yes I have had to deflate my 1:1 when visiting my dad in the Rockies. I live at sea level, heís at 8,000 feet. No they didnít exploded lol. But it was noticeable enough to affect traction in the snow.

Not sure why the sarcasm/aggression itís just an observation. Some guys vent, some guys donít. Do what you like to your RC truck and just have fun. I do a lot of things that may be a placebo but it is what it is, not losing sleep over it
