Wheels vs water Carlo here from South Africa, I am running a scx10ii, but scared of ruining my foams in water. Do i plug the air vents in the rim? What is the best way to do this? And doesn't that influence the traction? Any help would be greatly appreciated. Sent from my AMN-LX9 using Tapatalk |
Re: Wheels vs water A buddy uses screws in the vent holes to seal the wheels and removes them for regular running. I plug the wheels, vent the tires liberally and hope the water will spin out. Open cell foams don't last long in that scenario... |
Re: Wheels vs water I vent my tires. I have this tool which you chuck into a drill. If I suspect any water got into the tires I’ll spin them for about a minute each (no more than half speed with the drill). Gets most of the water out through the vent holes in the tire. https://www.amainhobbies.com/aka-12m...a44009/p531978 |
Re: Wheels vs water Vented is the only way for consistency. Eddie at CI put this foam guide together ( closed cells in water) Foam Guide Foams do not need to be confusing! Here are some basics you need to know... #1. The Crawler Innovations Double Deuce, Lil Nova and Deuce’s Wild Foam Systems are based on the weight and intended use of the your RC Vehicle, not the overall height of the tire. #2. The closed cell foam is water proof, and air tight. The tire must be vented to allow the foam and the tire to properly conform to the rock surface. No air movement = No tire conformity #3. Crawler Innovations always recommends stepping up one outer density for the rear foam pair of your RC Vehicle. The reason being is that the weight of the RC vehicle transfers to the rear tires on a climb. #4. There is no one magical foam that does it all. If you want maximum rock crawling traction, you need a Dual Stage foam. If you want maximum speed with no tire enlargement, you need a Deuce's Wild Single Stage. Crawler Innovations offers a number of tuning aids that will allow you to finely tune your foams, once you've reached that level of understanding. Not everyone wants to be a Pro RC driver, some are happy weekend warriors. #5. Wheel Weights: Crawler Innovations highly recommends knuckle weights. Do your best to keep rotating weight off your RC vehicle drive train. Your RC vehicle will last longer, perform better, and you can use the saved money from non broken drive train parts for other upgrades. However, if you do use stick on lead weight around your RC rim, all of the Crawler Innovations Closed Cell Inner Foams will need to be modified to clear your wheel weights without stretching the inner. When you stretch the inner, it increases the Outside Diameter and the foam does not perform as designed. A Dremel with a sanding drum makes quick work of modifying the foam. #6. Narrow Wheels with Standard Foams. If you have a Dremel with a sanding drum, sand the Closed Cell inner foam at a 45 degree angle so that it matches the width of your clamp ring. All of the VP bead locks are .750" width clamp rings, 1" overall. C.I. sells narrow inner foams, but unless your tire is narrowed, it's not properly filling the tire. #7. Dual Stage Foams and Water: It's a non-issue, even with the tires vented. The closed cell foam PUSHES water away. So even though water might be coming through a 2mm vent hole, only the outer will retain water, but the outer is being flattened as it is being rolled on, thereby, only a minimal amount of water is even allowed in the tire. At the end of your day of fun, simply hand squeeze out as much water as possible from your tires, then run the RC Vehicle at wide open throttle with the vehicle in a elevated position and the centrifugal force will pull most of the remaining water out through the vent holes. Store your RC vehicle in an elevated position to avoid flat spots in the tires and foams. Outer Densities: White foam / No markings = Soft Orange dot = Medium Black dot = Firm Hang up and Drive |

Re: Wheels vs water Venting your tires is completely a personal decision. I have some tires vented and some non-vented and I cannot tell ANY difference in climbing ability or control between them. The advantage of non-vented is that they are waterproof. Don't believe that you have to vent it simply is not true! |
Re: Wheels vs water Quote:
Huh? That’s nonsense, But whatever floats your boat. You really should read Eddie’s facts. My vented tires and foams don’t hold water either. Hang up and Drive |
Re: Wheels vs water Yeah my tires didn’t get squishy before I poked holes in them. Physics lol. |
Re: Wheels vs water Quote:
What is nonsense is to presume you know what's best for someone else. FYI, I have read the article and I simply don't agree with his opinion. The FACT is that you are free to vent or not vent your tires as you see fit. But no one can tell you one is correct and one is incorrect because I don't know how you drive and you don't know were I drive. Venting is simply one more tool in your suspenion tuning toolbox. Use it as you see fit. But don't arbitrarily tell people that venting tires is a requirement when it is not. |
Re: Wheels vs water Quote:
Well Eddie knows nothing then, Enjoy! He’s forgotten more about foams than you and I combined know. Hang up and Drive |
Re: Wheels vs water I mean I think in general we are free to do or not do any mod. I read something like that, consider the source, try it out...it’s really not a big deal I don’t think anyone’s forcing it on each other or maybe I’m naive lol. |
Re: Wheels vs water Quote:
BTW :My closed cell A.L.T foams wouldnt work properly if the tire wasnt vented |
Re: Wheels vs water Quote:
But go ahead, keep it going![emoji85][emoji86][emoji204] Hang up and Drive |
Re: Wheels vs water Don't vent, it's fun when you take your truck to a different altitude or temp and see your tires shrink or balloon :D |

Yeah I want to take my TRX4 to the top of Mauna Kea(13,800ft) and I wanna see what my foamless tires do, lmao [emoji23] Sent from my iPad using Tapatalk |

Exactly, holes in tires allow MORE water in! Still don’t exactly get the point in it, but whatever. I don’t believe in a “waterproof” foam anyway. I vented my perfectly good Canyon Trails, and guess what, after a few water runs, my foams were mush and were trashed. I’m going to have to agree with Inspector, I haven’t noticed anything good, only bad with vented tires. Sent from my iPad using Tapatalk |

Re: Wheels vs water My vented rims let water in but not out. I vented the tires and now (most) of the water comes out. Without venting you get less conforming to the sharp edges of rocks you are trying to climb over. If you can't tell the difference, don't vent. |

Re: Wheels vs water Quote:
Although like said above, if you do end up brining it up to drastically different altitudes, they'll shrink and balloon. 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. |

Re: Wheels vs water Quote:
Yeah, lol that makes since! It was about 2am when I responded, so I missed a thing or two[emoji1787]. I personally run non vented without foams and it grips great. Sent from my iPad using Tapatalk |
Re: Wheels vs water 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. |
Re: Wheels vs water Well that’s correct for single stage foams. However the world has Other foams, Two Or Dual (closed cell) stage.... that don’t hold water, relying on size and air space for proper grip. I’m in the Everglades.... I never use single stage foams. Hang up and Drive |
Re: Wheels vs water I don't vent tyres or wheels. Pro-Line says don't.. https://youtu.be/ht2ung1R4e8 Quote:
66% do not vent. https://i.imgur.com/FcQlKA8.png Quote:

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. https://i.imgur.com/4whIraL.jpg |
Re: Wheels vs water I think he meant like a major elevation change. As in a mountain. |
Re: Wheels vs water Quote:
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 [emoji23][emoji23] Sent from my iPad using Tapatalk |
Re: Wheels vs water 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 |
Re: Wheels vs water Quote:
Yeah, I bet it’s fun around Lake Tahoe[emoji106] We drove from Indy to Oakland to Seattle and I wish I would’ve had my rig with me. We went through the sierras and Rockies, I was so mad I didn’t bring it. I’m not going to be going near that 14k ft mark, There’s good spots at 0-4K[emoji16] Sent from my iPad using Tapatalk |
Re: Wheels vs water Quote:
Not sure why the sarcasm/aggression it’s just an observation. Some guys vent, some guys don’t. 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 :) |

It's great that the Pro-Line video where they recommended not to vent crawler tires, also answer the question about tire shrinking or ballooning. I was just outside driving in snow with 1:1 car, I've never noticed that the traction on snow is better or worse depending on tire pressure. We change to snow tires when it's 50F(10C), and on -40F(-40C) the pressure is still ok. We do check the pressure to keep the tire wear even, but not because of traction. |
Wheels vs water We do winter jeep trail rides every year. Everyone airs down before we leave the shop. The airing down increases the contact patch vs not airing down. Helps immensely in the snow. At our final spot where we eat, we air back up before getting on the highway. I only slow crawl rocks and never do water or mud, so my rc tires are vented. My vehicles do lose tire pressure in the winter. If I check the pressure before I go somewhere, there will be a 7-10# difference. After driving a while and some heat is generated, the pressure is back to where it supposed to be. My tires will even flat spot a little from sitting all day when it is -20F or colder. When I leave work, the car goes “thunk thunk thunk” down the road until the tires warm up. As mentioned before, to each their own. |
Re: Wheels vs water I know it's not quite the same as crawling, but LITERALLY EVERYONE in any class of RC racing will vent either their wheels or tires (or both). Touring, short course, 1/8 scale, indoor, outdoor, etc. It's simply more consistent. Now, to me it seems pretty clear that venting offers a performance advantage of some kind, even if it is miniscule, otherwise none the pros would be doing it either. (Before y'all jump on me, YES I have tried unvented wheels/tires while crawling, with multiple different wheels, tires, foam, and vehicle combinations. It does not work better than a properly vented setup). That said, I would not vent my tires/wheels if I regularly drove through mud and water; it indeed does destroy the foam pretty quickly. |
Re: Wheels vs water I'm not going argue which is better because I don't know ;-) But tires conform very nicely without venting. I usually run CI single stage foams which allow an air gap between foam and tire and this works very good for me at least. https://uploads.tapatalk-cdn.com/202...c2a913f5ba.jpg https://uploads.tapatalk-cdn.com/202...5f095a42fb.jpg https://uploads.tapatalk-cdn.com/202...6b1e3db585.jpg |
