I love Canyon Trail's, I've never even had a TRX4 and I run them on my SCX10 and ECX Barrage. Thanks for all your videos, you're always the most consistent and concise resource for RC stuff like this on the platform; your presentation is so 'up my alley'. I personally wrap rims in some solder like you, then 4 weights, then tight electrical tape around the whole thing; helps re-installing the tire and situating the foams inside. I also love soft wheels; so with all that inside the rim; I got proline soft outers, and cut stock inner foams for dual-stage open-cell foam pliability.

[@33fastcar]

Brass & Hyrax, brass & Hyrax. Changed my TRX4 crawl for the better.

[@Tookan69]

This video really helps, I just started building a TRX4 sport unassembled kit a while ago and I'm very close to finishing it and knowing things like these are always useful, thanks for the help!

[@adventureawaits4x457]

Can confirm. Putting those slits in the tyres made a difference!!! Thank you so much!

[@RCReviewChannel]

affirmitive

[@jdssurf]

Where did it show that

[@Isaac804ab1]

These tires cut like that are insane

[@havn2muchfun]

Simple green works well for cleaning as well. Also works to refresh old tires

[@RCReviewChannel]

Yes. Breaks down the rubber a bit so gives it extra grip. Use every once in a while.

[@zsrc3623]

I just added 4 oz of wheels weights onto my SCX10 iii. Gonna give them a shot this weekend. I effectively doubled the weight, for starters only put in the front, but i may put half as much in the rear as well if i decide to after testing.

[@dezfan]

Simple Green is an excellent way to remove the release agent and get your tires natural rubber tackiness to its peak.

[@comeandtakeit5709]

I heard it also takes off the chrome from the wheels if you soak them in it?

Great tips👌👌 They just keep coming👍👍👍👍

[@thecandyman9308]

Wow, big improvement

[@Evan_Moore61]

I definitely have to try the knob modification on my tires. I just need the snow to melt up here in Michigan so I can go out and have some RC fun without freezing my fingers off.

[@RCReviewChannel]

I hope winter ends soon for you. Good year to crawl.

[@JViello]

To add to my last comment, I also recall trying 2 oz of air rifle BB's in a pretty much stock RedCat Everest 10 just for fun. That thing climbed like a billy goat! Because the BB's always stayed at the bottom of the tire the truck could almost climb vertical without flipping backwards! It sounded a bit weird though. Kind of like waves crashing over and over as the tires rolled forward.. LOL Couldn't argue with the results though!

[@Inching.Islands]

Ball bearings are the way forward, even moreso on the smaller scales 😀 like my 1/24 modified rock and trail crawlers in a living miniature outdoor landscape.

[@tnpis4me]

I use wheel weights also but i always wrap them with a little electrical tape to hold them in place if they come unstuck

[@ka4172]

Damned never no the film on the red Cat tires thank you for this cleaning tipps!

[@Tuidkskiwjdhdbd]

Thanks love it and just got my first trx4 about 3 days ago and I'm hooked i also have two sons now there hooked also

[@zincyellowmach1523]

Awesome video, always loved these tires even stock. Your channel is great!!! Electric bread knife cuts foam like butter btw, give it a try!

What kind of rig? Traxxas tires?

[@dangavin]

Gregg K check my channel, also stock tyres

[@rcbigsmall5810]

[@RCReviewChannel]

Modding is fun. And when it works and it's free, even better.

[@operation11charlieinc]

Good stuff brother

[@BobL1]

Thanks for the information.

[@TOYitCUTE]

actually the canyon tires are no that bad at all ,the foams are the thing to change just out of the box ,something like pro line or laserfoam ,or just add some larger foam ring to this ,it works much better ,or freeze the wheels in refrigerator before closing the rim vent holes with a piece of some tape -air expands and makes nice tire pressure effect ,it works nicely ,i did it quite often in winter crawl/wet conditions

[@RCReviewChannel]

Very good advice!

[@kandscustoms1122]

Put the slits on the tires including the sides as well, Works like a charm, Thanks for the tip...……….!!!

[@RCReviewChannel]

great suggestion

[@timjohnson9406]

Great info!!!

[@gheorgheoltean4467]

Great mod! 😄👍👍👍

[@RCReviewChannel]

Yes!! Check the other suggestions too.

[@travispratt6327]

Solder is a great idea.

[@zkgarage1939]

You can also put the sodder in the wheel and also put weighted tape on it.

[@JViello]

Old racing trick: Soak your tires in WD40. It softens them and makes them incredibly sticky. If you have decent tires already and just want them better...Get the tires wet with WD40, put them in a large zip lock bag with a little more WD so they stay wet. Squeeze the air out and seal. Let them sit 4 to 6 hours and check. For hard crap stock tires let them sit overnight. Sitting overnight will turn them into jelly. BUT, they will get more firm and usable after a few hours so don't get worried. Using a tire treatment like VHT will give you insane traction. (Ever see those drag strip videos where they are walking on fly paper and people lose shoes? That's VHT) It's really designed for track racing but if you are in a competition, it will at least give you crazy grip that slowly goes away as you progress through the course. Even for a trail run, the treatment does prep the tire and make it more pliable etc. Far as I know, there is no downside to running it aside from random leaves getting stuck to your tire. LOL 1/4oz wheel weights with adhesive from Amazon are cheap and work as well.

[@solngv8]

In the indoor dirt RC racing world, we clean our tires with Simple Green and apply Liquid Wrench for traction.

[@RCReviewChannel]

Yup, done that. In the dirt though, it will attract all the dirt.

[@greggk1061]

Love free. Have tried the wheel weights and it's really good. That is one advantage of beadlocks as they're always heavier. There are new kits by CrossRC and the wheels come with wheel weights and each wheel weighs about 150 grams box stock. #gamechanger

[@RCReviewChannel]

Heavy wheels ftw.

[@diycaravanning6507]

You could use flashing lead and double sided tape to weight the wheels.

[@OtherSide..]

You're a genius great videos

[@RCReviewChannel]

I'm not the worst.

[@ShenRC]

👍 Good stuff! I found just by putting 2 vent holes in my TRX4 sport tires o posit each other in the tires made my tires feel softer and did make them get a bit softer after a few runs.

[@RCReviewChannel]

Vented wheels with two vents is key.

[@ShiazVivek]

when you boil how long you hv to keep it boiled for the glue to met out. thanks for awesome content

[@dschenk952]

Thanks for all your contributions. One question, do you find boiling or baking better for breaking down the glue holding the tire onto the rim? Those look like they came off pretty cleanly.

[@RCReviewChannel]

Do not know. These came on a TRX4 assembly kit and was NOT glued, thankfully.

[@sportcustom7141]

Baking stinks up the oven and the house your wife or mother will not appreciate that very much, boiling never worked for me, acetone may eat the tire or the wheel and the foam, and their is the method of using a heat gun keep it a few inches away from your wheel and tires work in small sections at a time focusing on where the bead of the tire and wheel are where the glue is. It is ime consuming but works. Becareful not to melt your wheels, wear thick leather gloves, and work in a well ventilated area.

[@mitch_smith]

Have you tried lead tape on the rims? it comes in various weights, but its around 3 dollars for 6 feet.

[@perry5643]

On the inside stock trx4 wheels I filled with bbs glued in with jb weld.

[@ka4172]

its need a before modify testdrive and after modify drive . Your Defender body need body protection many cracks in the corners.Nice Video.

[@RCReviewChannel]

True!!!

[@transambill1]

You can get wheel weights at most tire shops with adhesive backing on them really cheap to add weight to your tires. They come in strips of one oz and half oz segments.

[@herbbates4713]

So never seen what glue to use to glue the TRX tires back on

[@alecsimmons1120]

How about tire venting? A leather punch is nice and clean what size hole would you recommend? Also is it better to do it in the sidewall or the tread? I am in dire need an answer! You guys are there crawling gurus around here! All of my local hobby stores have a completely mixed opinions... also I have a brand new TRX four sport and contemplating adding weight to the front. At what locations would you recommend for that particular vehicle. I know you guys are very well-versed in Traxxas RC ‘s. Thank you very much for your time in the consideration. Keep up the good work!

[@RealJawnes]

Two vents opposite from each other is very good

[@carlcarl6032]

Little inner tubes made from condoms work better than foam.

[@RCReviewChannel]

new or used?

[@carlcarl6032]

@@RCReviewChannel It depends on if you want them weighted or not.

[@RCReviewChannel]

lololol

[@gpaje]

How much would you say is too much weight for a wheel/tire combo with added weights?

[@wootley]

Excellent video, could I please ask what size foam fits in the standard TRX-4 tyres, I would like to ensure I order the correct size.

[@barajastony0]

I think they're 2.2 tires so a foam for that size would be right

[@RealJawnes]

@@barajastony0 no they are 1.9 tires

[@AnthonySvt_]

Can you make a video on shock oil?

[@nason43]

Do you plug off your vent holes while you have wheels apart?

[@RCReviewChannel]

No, we don't plug the holes. We believe they vent holes are essential to prevent air pressure from building up and interfering with the action of the foam. When we run in water, we plug the holes or we drain the inside of the tire and dry out the foam after.

[@ka4172]

Got new foams fit any weight and dont suck water (amazing performance).More information on RC.HP on F.B. (A.L.T. Foams)

[@RCReviewChannel]

thank you for that.

[@Friskee62]

What about venting your tires? I do that all the time...

[@rrenegadoo]

very interested, ......BUT..... at 6:12 you explained the appropriate wheel rotations.... at 8:39 I can see the front tires spinning on the right way.... at 9:35 the rear tires are rotating on the wrong directions..... ?????

[@RCReviewChannel]

Just noticed that too. The rear tires were mounted wrong!!!!! Could have performed even better. Front tires are everything for steep climbing.

[@Cachapeluo]

Do you guys vent the tires?

[@SierraCrawler530]

If you look at the trx4 defender the tires are on backwards in the picture on the front of the box very weird right

[@srtallday3655]

Do you have to glue the tires on for a crawler? What would be the upside and downside if any to not gluing it

[@RealJawnes]

You have to glue them if you don’t have beadlocks because they won’t stay on and they will slip.

[@namenames7851]

What about the tire being full of water with a little give ?(squish)

[@ivorytitan7653]

So i want to change either the foam or the tire but keep the rim becuase its a camel edition and i love the original rims. i want to change it because i stupidly waded the truck in mud water before sealing up the breathing hole in the rim. then before it dried out i sealed it with hot glue. so now i get imbalances and the tires are a bit squashed. Any suggestions?

[@transambill1]

Preheat your oven to 300 then turn it off. While waiting on your oven to reach 300 degrees wrap your wheel/tire in aluminum foil like a baked potato. Put the wrapped wheel /tire assembly in the oven for 15 minutes then pull out of the oven and using a towel so you don't get burned,unrap and pop the tire off the wheel and set aside to cool. You can then wash the inside of the tire and foams and let air dry if you plan to ever reuse in the future.

[@ivorytitan7653]

@@transambill1 Thanks! I guess just use tire glue to stick them back together?

[@Heggatron]

Are the 150g a good weight for your wheels? I got some aluminum beadlocks from ebay which have these 5g metal plates all around them. Complete wheels with tires weigh 250g... is that too much?

[@travispratt6327]

Did you decide on a good weight for tires?

[@Heggatron]

@@travispratt6327 about 200 gramms. But new, heavier steel beadlocks an without added weight plates around the rim. So the rotational mass is more in the center.

[@travispratt6327]

@@Heggatron What crawler you got? I just bought an Everest 10 and deciding on wheel weights, today I think I’m going to try free ballast bbs or pellets and see how they run, seems to give some unique advantages like always lowest possible cg and should be easiest on the drivetrain.

[@Heggatron]

@@travispratt6327 sounds good. But no foams then? I have an element Enduro gatekeeper. Good platform and I like the style of the body. But because it's made of molded plastic an not just thin lexan I really have to get the weight low.

[@travispratt6327]

@@Heggatron Yea I guess the weight of the ballast can replace the foam, since foam just tries to push the rubber to the ground and the ballast will be doing that.

[@junelopez9520]

That's what she said

[@paklahaccord997]

That foam is 117mm or 120mm

[@lowndawg420]

can i do this with any type of rim or does it have to be a beadlock rim???

[@JRLdesigns]

You can do this with every type of rim, however, the stock wheels on the TRX4are not beadlocks, and you need the remove the rims themselves from the tires.

[@enigma9789]

dude puts $40 worth of solder on the rim. " I haven't costed you any money so far."

[@DriftomaniacsRC]

a video on removing the glue would help as EVERY video I've followed on youtube to remove the glue has failed and resulted in tire write off

[@RCReviewChannel]

We actually have no experience with it. What techniques did not work for you? Can imagine premounts are harder to take off.

[@DriftomaniacsRC]

@@RCReviewChannel I tried with my axial SMT10 tires as I'd stripped the wheel hex but the tires were fine until I tried removing them, I tried boiling, baking, acetone and none of those worked the inner edge remained firmly glued. I end up buying new tires/rims. You mentioned removing the glue so I thought you may have some ideas on it. A video on that, with a way that works would be v. helpful

the beat way ive found is an acetone bath.. racers have been using that technique for years

Old tech new again

[@Clavitz1]

I think im a very small minority here, but I actually want harder foam. get me closer to the "realism"

[@RCReviewChannel]

Harder foams simulate normal street and freeway driving. On rocky trails, real 4-wheel vehicles aird down their tires to about 12 psi to get some performance.

[@Clavitz1]

@@RCReviewChannel ok. I just felt like some tires squish way too much that they come off looking like they would be tires low on air on a real car. thanks.
