Tire Modification



I’m sure most of you have a few old tires laying around. Maybe there are some that you ran a few times, but they didn’t perform how you wanted them too. Tires are one of those things that are really a preference for most. Some guys swear by their tires. I think it has a lot to do with foams, set up, compound, and your terrain.


Well if you have some tires that you are not using for whatever the reason or if you just want to do something different, this may give you some ideas. I am a fan of the Axial Maxxis Trepadors and I have a couple of sets, so I am going to experiment with them and show you this modification process.

Tools and parts you will need:

- Tires (any will work)

- Dremel with cut off wheel

- Wheels

- Wheel weights (optional)



A dremel and a cut off wheel is all I am using. For me a higher rpm seems to really clear out the groove quick and clean.


One pass and I opened the pattern up considerably. You can go smaller or bigger, that is one of the cool things about this. I will also run a factory set of Axial Maxxis Trepadors as well as my modified set. I will record this and give you my opinion of if it really helped or if it just looks cool.


Another pass and I am going to open the other side. You can do something simple like this and stop. Just run it and see what you think. You can immediately see the difference in the picture below.



I am going to open the center cuts in the middle of the tires. You can compare my cuts to the stock factory version and see how much I am opening the tread pattern.



I have gone this far, so I am going to open the horizontal grooves on the small lugs. Just a quick hit with the dremel on these and you’re done.


Well here is my cut beside the factory version. It looks more aggressive for sure, but I am not sure if that translates into better performance. If I had to offer a tip on this, it would be take your time. It’s not hard, but its not quick either. This is 15 to 30 minutes a tire, depending on your skill level. You can squeeze the tire to see your work better, while you are cutting.


To make this a fair comparison I am running 3 oz aluminum wheels, with tape weights on the fronts. Here in Las Vegas this is common because we have some close to vertical climbs. I am going to use the stock Axial foams that come in these tires.




If you have never done weights on your wheels, I can tell you these are just tape weights from a local tire store. Some local Hobby stores actually carry these. Simply peel the backing and wrap it around your wheel. This works on plastic wheels as well.



If you keep the weights in the center this will help you out. You don’t want it to interfere with the beadlocks or anything.



So here is the cut version all mounted up. They look like a new tire at first glance.



Here is the factory version all mounted up.


Now to take these out on some terrain and see how they work. I am going to take them to Logandale and see how they do on sandstone and a little sand. I chose this area to see how they grab onto loose terrain. We will see if modification helped or just changed the look.

So here is the first run out at Logandale. I am going to run each line 5 times, I am posting the best run on video for you to check out. It’s not about the set up; I want the tires to do all the work.

After the first run, I think it’s fair to say the modified tires grabbed the rock more quickly than the factory tires. Though I should tell you that with momentum, both tires made this climb relatively easy. I am crawling it to see how the tires work.

On this second run I will go up an uneven climb, and some loose sandstone, almost like shale.

After the second run I feel the modified tire was again able to grab the rock a little better in some situations. These are the best of 5 runs. I am running an Axial 55T motor, Axial AE-5, with a 2S lipo to ensure smooth steady power at low speeds. On the loose terrain, the very first run was the best pass for the factory tire. As the track wore down it slipped more. Although the modified tire slipped as well, it consistently drove the same in deteriorating conditions. Next I will run in some deep sand with a slight incline.

After running in the sand, I can say when I buried the tires to the point of no more forward progress, both tires were able to reverse and get themselves out. I feel the factory tire did better consistently. If you notice, the factory tire stayed on the sand better. The modified tire almost had the differentials on the sand every run. With lower power, the modified tires wanted to dig. With big power I am sure that maybe it’s fine, but this was with a 55T motor, so advantage factory tire. On this last little run I am going to the rocks of Lone Mountain Park here in Las Vegas.

So after this run I think the negative spacing and cross cuts on the lugs helped out. The factory tires wanted to spin a lot on the vertical flat climb and the modified tires went up easier. The last climb was a vertical climb just so I could see what the modified tires would do. I was impressed.


So what can you take away from this? Maybe you need to break out those old tires and see what you can create. I hope this inspired you to try something new, create your version, and just enjoy what you have. This technique would work great on Axial RTR tires as well. You might end up creating some great working custom tires.

Scale Detailing Your RTR



I am pretty sure you all have some old bodies sitting around. It seems like everyone who gets an Axial RTR tends to take the body off and change it out, just to be different. Hopefully this will help give you ideas to make your RTR body different. This is not really about being precise, its more about a complete look, so don’t be afraid to mess up.


I put on different stickers to make mine look different, then I cut the rear cage just to change it up a bit. Now I am going to go back to running this body as I have always been a fan of the Axial Honcho.


This is pretty stock other than a cut rear cage, a few stickers, and plenty of scratches.

20160822_134603 20160822_134538


There are definitely a few ways do this. You can use a heat gun, a hair dryer, a wood burning tool, and so on. Here I am going to use a lighter. I like scale, so I am not looking to make huge dents. You will see that lexan gets glass smooth when its hot. I just used the back of a wooden paint brush to create the dent below. Try not to use round objects; there are not too many dents with perfect shapes, so keep that in mind.


You can see where I dented the pillar. It’s not a crushing blow, but a noticeable dent.


While looking at this I am going to do away with some of the scratches on the windshield. I cut along the black molding on the sticker and under windshield banner. You can also remove windshield banner if you like. You can use an exacto knife or razor blade.


Simply peel away the clear sticker on windshield and here is what you get.


Some of the scratches are deep and went through the sticker, but that’s fine. You can incorporate those scratches in this next step.


Take your exacto knife and start scratching some cracks in the lexan to give that broken glass appearance. For darker or bolder cracks just hit the same spot twice. I started a small and tight pattern before going into the bigger cracks.


Pictured above is small pattern I started with, picture below is how it looks finished.



Going back to the dents, I am going to scratch off paint from the inside. Again, there are several ways to do this and there really isn’t a wrong way to do this. Here I used a body reamer to start. try to leave some of your existing paint in the dented area.


I am using some silver model paint. It may not look like it shows up too well, but after the next step you should be able to see it better. Try not to paint all of the scratched surface silver, you will need to add some brown for rust.


It may not look noticeable yet, but it will. You can also scratch the surface again if you feel like you want to add more.


After the silver, I added a few new scratches with a dremel, then covered it all with brown paint.



Now maybe you can see it a little better.


I added another dent, I went over this one with a Dremel. Same as before, I will add some silver, then cover it in brown. If you do not like how it looks don’t be afraid to go back and hit it again.


20160822_162855 20160822_163543


I am happy with the dents, but I don’t think the window would look fine after hits like those. Time to put the cutting wheel on the dremel. You can also cut the windows with a body reamer and body scissors.


If you want you can use a scrap piece and make a template of your window. You can use the template to set it how you want the glass to look. I start by cutting it to the height I want.


I always just rough cut it to start and will clean it all up at the end.


I want the window like its off the track, so this is an example of how you would use a template. Set the template next to the body like it’s your window so you can get that scale look and keep the right shape.


I clean it all up with a sanding wheel on a dremel and an exacto knife.

20160822_170552 20160822_170554

Don’t forget to peel away the sticker on the side window.



Here is the body reamer method of removing windows.


Ream a hole and then use your body scissors to cut it out. Again I will clean it up with a dremel, exacto, or razor blade.

20160822_170948 20160822_171321

After looking at this, I feel it needs some dents showing what that would break out this window.


I dent it with the lighter and the handle of wooden paint brush. Then I Dremel some paint off like before, add silver paint, and then the brown.

20160822_173031 20160822_174206

Now I get some duct tape and cut a corner off of a trash bag.


Rough cut the bag to the size of back window frame.


I cut the duct tape to a scale size and tape it inside and out for the look I want. This works on any body, so be creative and create the look you want.

20160822_175506 20160822_175718


Now for the cage. I cut my cage down; I have this spare Axial Dingo cage so I am going to use it make a rear section for this Honcho.


I start by cutting it down. I left the plastic gusset section for aesthetics.

20160823_154359 20160823_154534

I drill some holes so I can attach this cage to my existing cage.

20160823_154705 20160823_154803 20160823_160003

Once I attach the front section, I simply drill on the underside to attach the rear. I missed my mark the first time, but I don’t think you will notice it when it’s done.

20160823_160015 20160823_160144

Once I attach the rear section, I am looking at the parts I have left from the Dingo cage. I have an idea…


I like the look of this section so I am cutting it to use it.

20160824_091011 20160824_091049

Looks good to me so I will just keep trimming it to fit. I am using a dremel with a cutting wheel.


I have drilled a hole through the tubing to attach the new piece I will use.


If you counter sink the screw, it will not stick out and it almost looks like it’s made this way.

20160825_083033 20160825_083353

Here is a tip for you. It’s very hard to drill into a round tube, so start it with a body reamer and you will find it’s much easier.


So I have my new piece in, held in place by screws in the bottom. I am not digging the old spare tire placement though. Maybe its overland meets racing.

20160825_090559 20160825_090610 20160825_090629

I like this look a lot better. On your build feel free to try new and different things. That is one of the great things about this hobby.


Even though I changed the cage and the way the spare tire sits, I feel it still needs more to be different.



I break out the dremel once again. I am going to remove all the paint from one fender. I want to do it on the wrecked side.

20160825_111847 20160825_111836 20160825_112054

You can also do this with sand paper, or I know some people use chemicals like Nitro fuel or store bought products, but I want a rough look.


Once I have my paint removed, I will mask it off and paint it. Make sure you mask the windows too.

20160825_120703 20160825_122926

So here I have my black fender. It looks like its a flat black, almost like a replacement fender before the primer. You can do this on any body in any color. Pick any body panel or panels you want.


Looking at it more, I want to fill the voids under the bed towards the cab, so I’ll put a couple of scale items there to fill it in.


A scale propane tank and an old plug will work.


To secure it the propane tank, I drill a hole in the tank and run a screw through the top of the bed. You can use a spacer between the tank and bed for height adjustment.


You can see the screw head on the top of the bed. Cut the plug off the plug and use Shoe Goo to hold together each end of the wire. I used the body reamer to put a hole in the bed for the propane wire to feed through.

20160826_213239 20160826_225616

Next, I will put dual batteries in the other side to fill the void. This is a short light bar mount from an Axial parts tree.


I heated the plastic and bent it. I will attach this the same way as the propane tank.



I want an expedition style look. I went to a local fabric store and bought this Tan cloth for a couple of dollars. I also bought some black elastic square chords.



I pinch the fabric between the body and cab.


Simply remove the screw that attaches the body to the cage and you can pull the cage away enough to get fabric in. Just put the screw through the fabric and back into plastic.

20160905_183905 20160905_183922 20160905_184054

Pinch the fabric on all four points of the cab, just as the first one.

20160905_184131 20160905_185550

For the rear, I pinched the fabric under the rear portion of the new cage I added and the bed. I like the flat side look of the canvas, but I want the driver side to be different.


I simply cut the side so it looks rolled up.


I am not going to sew this or anything. I’ll just Shoe Goo the fabric together around the rear roll bar.

20160905_200401 20160905_200358

I trimmed off the access pieces from the rear to clean it up. Again, I used Shoe Goo to glue the fabric to itself.


I am just screwing the fabric down on the rear, I am adding the flat elastic cord and pinching it down with a screw.


I drilled two holes and attached the elastic cords to the top. This does nothing; it’s purely for looks.

20160905_202041 20160905_203206

For the open side I am tying a knot to the roll bar on the bottom.


Next, I drill a hole (using a body reamer first) in the top roll bar for the elastic cords to attach to.

20160905_203510 20160905_203603

I tie the cords to screws and trim off access.

20160905_205014 20160905_205141 20160905_205149

I’m satisfied with the overall look, but I need some contrast with the spare.

20160905_211330 20160905_211341 20160905_211355 20160905_211733

I have this mount I got from JRC (Judd Rummage Concepts) and I bought some red ribbon. I used this set up on my Axial SCX10 Chevy Baja build.



I like it. The spare is pinched in by the cage and it’s pretty snug.

20160905_213523 20160905_214526

I can add some scale items or do whatever I want with this side.


Here’s another tip - if you use a sharpie to make the body lines, you know it’s sometimes hard to stay exactly on the lines. Don’t worry though, you can easily fix this. You can see where I went off the lines. Pictured above and below.

20160906_082740 20160906_082933

Now it’s gone. Use some rubbing alcohol and a Q tip or rag and you can wipe it off. You can wipe it completely clean and try again or just remove the line you want gone.

20160906_083012 20160906_083017 20160906_083045 20160906_083259

The lines just add to the overall look. It’s your build so it’s completely up to you. When it’s all done you should end up with a transformed body.


On Part 2 of this blog I will do a simple interior, driver, and some lights to complete this truck. Hopefully it was helpful or at least gives you some ideas. Don’t be afraid to try new things. We all start somewhere. If you’re new to the hobby or customizing, then you should know this is all about being creative and using anything that helps create what you envision.
