differences in SCT wheels, does it matter?

[KnowAir]

I was cleaning up some old wheels and noticed a big difference in design on my traxxas slash wheels versus just about every other SCT wheel i have. I'm wondering, can i mount a non-traxxas tire with a non-traxxas insert on traxxas wheels? or will the difference in internal design mess up tire and make it perform poorly?

virtually every other SCT wheel:

What's the width of the void area you need to fill out? I was thinking maybe something like this below could be applied to the wheel before the insert/tire?

Why does Traxxas make it super hard for their users/customers. Their the only brand that uses dual profile foam inserts and wheels in the short course world. Emailed them yesterday, haven't seen a response yet. I can only find dual proline / dual stage inserts for rock crawlers.

You know why Traxxas did this? So you are only limited on using their wheels, inserts, and tires. (This is also because they only sell their dual profile insert with their tires only and it is not sold separately to my understanding.

Traxxas, the #1 issue in the RC world.

I agree, they do things different just to trap you in.. stinks. Proprietary.

Agreed as well. I would have went for my regular DE or Jconcepts wheels, but I like the blue ("fake") beadlock wheels that Traxxas has and they do well with my color scheme.

Tough call.. "show or go?" LOL. I understand, wanna look good at the front of the pack! Me? I'm the ugly duckling bringing up the rear! LOL.

Could always use expansion foam for the voids.

Or spray foam

That might work out ok. I'd be concerned it doesn't hold up under the stress. Not sure if that foam will hold up under cornering and high spinning forces.

Thought that too. But there's really no place for it to go? The closed cell outer should hold it in place. Maybe use some E6000 to glue it to the wheel?

I once made a set of inserts for some Xmaxx tires. The stock open cell inserts disintegrated, but the tires were like new still. Traxxas doesn't sell inserts without tires. The Xmaxx uses staggered inserts, just like the sct wheel. I used a strip of foam like in the link I shared earlier, bought some 4" thick 24x24" memory foam and cut my own doughnut inserts from it using some plywood templates and an electric carving knife to cut the foam. I went too small on the OD, but they worked quite well. Till the crappy Xmaxx tires started blowing apart. That was the end for me and Traxxas tires, LOL.

i have other wheels to use. i just wanted to keep my slash looking stock when racing.

Yep I see what y'all talking about. Starting to notice it on my carpet tire set. My right front tire. I notice a soft spot where the dual stage / profile thing comes into play. Outer side of the tire is a soft spot. The inside of the wheel/tire is like normal.

So an old racer was telling that you can cut the tire with some good scissors around the outside. Kind of in the middle between the bead and the top of the tire. Replace the insert or experiment with other stuff and then reglue the tire together. He said that's what they used to do years ago before closed cell foams were common. He was actually doing it to his daughter's truck because the raw speed foams are very hard.

I wish I'd known this trick before so I could have experimented with it. He said the rubber tire to rubber tire bond is really strong.

Simple answer to question. Yes, it matters.
Not only the design of the wheel matters, but the offset/backspacing as well.

SCT platforms designed to use 0 offset wheels; that same platform may be pushing the limits with +3 offset wheels (for some situations). Body usage, track enforcing certain rules... it can get a bit sketchy when buying Slash wheels for use on another brand of SCT that was not intended to use 9mm, or 13mm Slash offset wheels.

I have a set of SCTE offset DE wheels for my clay slicks. I went to the rpm offset front arms so that fixed the front and I'm planning to put a wider hex in the rear to widen the rear. Because with stock arms and wheel hexes I feel like the truck is super hard to turn around sharp turns with the 0 offset. But for my carpet tire set since I'm using Traxxas I'll be going back to DE and keep these Traxxas dual stage designed wheels for dirt tires if I get Traxxas BFGs in the future or any Traxxas tire for that matter since it's all proprietary tech.

Although I find it interesting a non Traxxas tire with open cell foams work on Traxxas wheel but not a closed cell foam. Tbf it can be my tire. Low profile harder compound tire vs taller and softer compound tire.
