Boom Racing Hustler 4.19 x 1.9 Snail Compound tire

 

A few months ago Jason over at Boom Racing sent me a set of prototype Boom Racing Hustler M/T 4.19" x 1.46" Snail Slime Compound  to try out. When I first took them out of the package I was impressed with all the scale things that are written on the side wall, these items mean nothing to the performance of the tire but are just cool to see that level of detail in a prototype.

The inserts that came with the tires were a Dual stage insert ( just like the 4.45" version), But I decided to go with a set of custom silicon rubber inserts from Mike over at Rock Monster R/C (so I could give them and the RC4WD tires a fair evaluation) and then mounted them on a set of Gmade steel wheels. Initially I tried to use the Rock Monster inserts that came out of my Baja Claw tires in them but they were to tight when mounted, upon closer inspection I found there are ribs inside of the tire to stiffen them up under side load and makes the inside of the tire a tiny bit smaller than usual, and with foam inserts I don't think it would be an issue or even noticed. So that is when I called Mike and had him throw a set of inserts together custom for the tires and they fit like a dream and the tires had no problems mounting. The tires have an aggressive look to them but in my opinion not over done to the point of making them  look like a cartoon / unrealistic tire.

Let me start by saying I have been using the RC4WD Mickey Thompson 1.9" Baja Claw TTC Scale Tires on all my class 1 and found that in my terrain they work the best for me all around, so initially I was concerned that the tread depth being on the tall side and the compound being soft that there might be a problem with the tread folding over during a side hill or hard turn in extreme angles. I am happy to say I was wrong in my assumptions. Just like when I first got a set of the 4.45 version of these tires I had to learn how to drive again because I was used to my old tires being able to slide the tail around when ever I needed, instead the Hustler tires just stick like glue to the rocks (not a terrible problem to have) thus I had to plan my lines a bit different knowing I could approach at much more severe angles.

The first trip out was done on an SCX10 running the Boom Racing Hustlers mounted on gmade steel wheels and Rock Monster inserts, after the hill climb was done a tire / wheel swap was done and then re-ran using  RC4WD scale Baja Claws tires mounted on white Gmade steel wheels and Rock Monster inserts (setup off my wife's crawler). The intention of this trip was to test the side hill and overall traction of the tire VS. a known set of tires in an area we are familiar with.

 

 

Disclaimer - we are not a professional  film crew

We chose a spot that had dust free rock and in my opinion has good to average traction and the temp was approximately 80 degrees Fahrenheit, and wheel speed was intentionally kept low and consistent so all the emphasis would be on the tires traction and not just tear ass'ing up the rock.

I realize not all things come thru in the video so here is a break down of it

SCX10 9.458 lbs

twin hammers  7.804 lbs

Location 1 = 45 degree vertical with an approx. 90 degree right hand turn in it (also the location where we stopped and zoomed in on the tires)

Location 2 = 57 degree vertical with an approx 20 degree right hand sweeping turn and intentionally placing the left side over a spot of moss/litchen to create a loss of traction

Location 3 =57 degree vertical with an approx 15 degree left hand turn, the rock is more broken creating larger gaps in the surface

First up was Boom racing Hustler Tires: at location 1 they had little to no loss of traction (time in video 1:18), they did loose traction on the moss at location 2 just like expected but it was a loss of traction on the tire in contact with the moss and not a catastrophic traction loss and I  could remain completely in control of it (time in video 1:30),  at location 3 there some traction loss / wheel slip due to the increase in gaps in the rock but barely noticeable  (time in video 1:36).

Second up was the Baja claws: at location 1 there was severe loss of traction and small amount of loss of control while it was being recovered (time in video 2:10 - 2:19), at location 2 there was a catastrophic loss of traction causing the truck to slide to the right rear and they struggled to regain traction and forced a new line up the rock to be used (time in video 2:23 - 2:34), location 3 was not the same one used as with hustlers because after a couple attempts it was shown I could not use the same line at location 2 and it forced / slid me to the outside right every time (time in video 2:37).

Finally just for fun the Twin Hammers had a run at it running the Hustlers in 4.45", at location 1 there was no issues, at location 2 while driving over the moss there was almost no issues,  at location 3 no issues.

Just like the Twin Hammers pictures I had pictures of the scx10 with the tires side loaded but they were almost useless when I looked at them at home, in retrospect I should have swapped wheel and tires to the Twin Hammers for the side load pictures.

 


 

Since the filming of the video I have had a chance to try them on different rock and soil ranging from sandy washes to some of the most pristine rock crawler surfaces Arizona has to offer and here is what I found:

Pros:

  1. I have found that in most if not all cases they will out climb other tires and trucks up loose sandy surfaces due to the fact they can clean out their tread easily and not plug up.
  2. Unlike the baja claws that just dig down until the axle touches ground, the Hustlers can actually "chew" their way thru sand and loose soil by turning back and forth.
  3. They can stick to ridiculous angles even if there is light dust or sand on the rock
  4. un yielding traction on side angles

Cons:

  1. the un yielding traction is great but it will let you hyper focus on doing lines that you couldn't do before, and because of your lack of attention to your personal safety you are in danger of falling the down hill (laugh but that actually happened). - please be careful
  2. due to the increased traction your driving style will need to change, meaning that if you frequent the same locations and are used to being able to make a transition or a turn because of a geo dig or sliding around a rock, that might not be possible anymore. I found myself having to change my "tried and true" lines because I could not just come to the same spot and dig in the rock slide and swing the tail around like always, now I dig in the rock slide and the rear tire tries to climb the rock it used to spin on making me re-think my approach and the way I run the line. Not that having to much traction is a bad thing but is something to think about
  3. I did have one of the tires loose the bead while mounted to the Gmade wheels but it hasn't happened again since switching to the Boom Racing Krait wheels. I relayed it to Jason at Boom Racing and he told me it is a known issue and will be taken care of when the tires go into production (same problem happened to the pre-release 4.45 version of the Hustlers I have but was fixed when they went into production).

 

Overall I can't speak highly enough of Boom Racing's 4.19 Hustler scale crawler tires, just like the larger 4.45" version they have out performed other tires in every terrain I have had them in and the traction in side hills is just amazing.

 

I will add more as I think of it
