Softer tires for crawling

[waqr]

I am using the stock tires and foams that comes with the Wraith Spawn RTR. I assume this is the Ripsaw R35 tires. I am only using the Wraith for crawling and I noticed that the tires are pretty hard and do not conform that much to the surface when crawling.

What can I do to get softer tires for crawling? Punch a whole in them? Buy new foams?

Thanks!

I'd buy new foams. Either two stage or some single stage memory foam. Personally I'd get done different tires at the same time. I'm a fan of the Rock Beasts or Flat Iron XL's. You'll want more of a sticky tire than soft but they play hand in hand to a certain extent. Too soft a tire and you'll bind up on stuff more than crawl as well as loose a lot of stability on off camber obstacles.

Foams aren't going to do it. The Wraith RTR comes with hard tires. Even the R35 compound is not that great.

Check out the new ProLine 2.2 Hyrax, Flat Iron, or TSL Super Swamper tires. You can get the ProLine dual stage foams to go along with it.

Thanks for the replies. Will all 2.2 tires fit the stock Wraith wheels?

Some 2.2 tires will fit the stock 2.2 wheels. I personally haven't had any luck getting ProLine 2.2 tires to work with the stock Axial beadlock wheels.

Ok, but if I want to use the stock tires (since they are almost brand new)

What is the best way to get these softer, new foam or punching a hole in the tire or wheel?

Shave/clap the sidewalls and trim/sipe the tread

[altd896]

Definitely check to see if the wheels have been assembled with the vent holes open, if not adjusting for them to be open will definitely help.

While dual stage foams are the go to you can modify what you've got, trim down the outside diameter a little so they're not stuffed into the tire so much will make it softer.
Can also try star cutting the foam in it's current size, will make the tire softer.
Neither will probably be quite as good as dual stage but neither will cost you anything to try either.
Seeing yours was the RTR Spawn I don't think that had the R35 compound tire.

If they are the hard compound tires you might be able to take out the foams completely. As long as the rig is mostly stock it will be light enough to work well without them.

I had some r35 ripsaws and thought the rubber compound worked fairly well.
Just don't like them 'cause they don't replicate any 1:1 tires.

How soft does it need be ?

Too soft and it will have yer servo working overtime
trying to turn those tires as they fold over or buckle.
Side hilling can be even worse.

In 1:1... airing down a tire to say 6 psi
is usually reserved for very slow rock work
and should never attain any speed or hard turning.

Try some Crawler Innovation 'Lil Nova dual stage foams
those are the best out there for conformity and moderate speeds.
but can still be firm enough to work on a trail type terrain.

The outter foam rings can be had in soft, med or hard compounds.

The weight of you crawler has a lot to do with foam insert selection.

The stock foam inserts that are included in the kits purdy much suck.

Call Crawler Innovations CI Lil Nova
and they will help you in your selection of their products and which is best suited for your needs.

Xl's on stock foam narrowed about 5/8" on axial ifd's with gpm alloy faces.



A bit of trouble but not impossible.


If I'm not mistaken all axial wraith rtr's came with R40 tires do they not? I just picked up an rtr wraith and the tires are complete garbage. Hard as a rock with not foam support. Just because they're new doesn't mean they don't need to be replaced. Replace them sith a tire not made of plastic and you'll be happier in the long run.

You have more patience than me. I've tried putting Prolines on a couple different Axial internal beadlock wheels with no luck. Maybe I give up easily because it's a reason for me to "need" a new set of aluminum wheels.

The Poison Spyder Wraith comes with R35 compound tires, but the tread is shit. The Spawn kit comes with S30 compound Treps - whatever S30 is. I think the rest of them come with rock hard tires.

[WHITE-TRASH]

S30 is between 35 and 40. Makes sense I know, but calling it 37.5 just doesn't have the same ring to it.

R35 is on par with proline G8. Other than tread design I bet you couldn't tell a difference in performance.

I know the R compounds, but I don't know the S compounds. Didn't know they called it an "S".

I was under the impression the Poison Spyder Wraith had the R40 compound Krawlers stock?

It looks like you're right. I misread Axial's website.

Axial's site states, "Officially licensed BFGoodrich Krawler™ T/A® KX tires! In the full-size offroad world, they are the winner of more rock-crawling championships than all other tires combined (Race spec tire, Years 2004 through 200. The Axial version captures the same aggressive look you’ve been waiting for in a durable high mileage S40 compound. Also sold separately in Trail/Comp sticky R35 compound: AX12021 2.2 BFGoodrich Krawler T/A - R35 Compound (2pcs)
Note: “White Dot” indicates R35 compound."

no worries... I looked it up because you had me second guessing myself.
I found the same information.

I have nothing to add to the discussion other than I asked Mr. Santa to please put some 2.2 R35 Trepadors and some CI foams under the tree this year. If that happens Ill chime in. (Currently running 5.5" cut and shut Proline hammers from like 2007 when i was into rc'ing back then)

What made you want Trepadors? I'm not a big fan of those tires. Most people remove tread in order to get them working well.

I'm a big fan in the 1:1 world along with the Krawlers. Likewise, in the 1:1 world I am not a huge fan of the Pitbull Rockers because from what i have seen they aren't that great at one thing.(although from the reviews in the r/c world they are the Bees knees)

At this point I'm sure they'll be better then the tires I am currently running. and since i am just getting back into the rccrawling world, I'd like to try different tires out starting with the tires modeled after some of my favorite 1:1's. (now if we could get a nitto trail grappler replica!)

I like my R35 Treps... and I think some folk underrate them.
Or confuse them with the R40 compound.
IMO they do purdy well with dry rock climbing...
tho' for mud/wet terrain, there's better.

To get more traction outta the Treps... some sipe the lugs.
But I don't...
because if tire spin and higher speeds is the goal
that can more easily shred those lugs, destroying the tire.

For mud/loose terrain work... I'll install my PL TSL's
Have both SX and XL's in 1.9's (SCX-10) and 2.2's (Wraith)
And I'll switch them... according to the terrain and my wants/needs.

IMO... one should have more then one set of tires/wheels
and they should be swapped out for the various terrains/conditions.

Sometimes a tire that is too soft...
will bite too much when cornering and just flop over.
Especially when driven/turning at higher speeds.

Sometimes a tire having a harder rubber compound
that slips rather then bites... will do better for some
depending on what they're doing.
And the harder compound tire's will hold up longer
to wheel spinning abuse.

But because I generally crawl slow... with minimal wheel spin
I prefer the softer rubber compound tires. ( ie: R35 - G8 )

Sometimes the best opinion of what tire works best for your needs
and the terrain they're driven on...
...is your own.

IMO... I say invest in at least two sets... for various conditions.
and alternate them for the changing conditions.

Because RC crawler tires are like shoes.
Who wears the same shoe for every environmental condition ?
