Tire Gluing
The factory tires on your T-Maxx 3.3 are already glued to the rims. 
The tires must be glued to the rims to prevent the rims from spinning 
inside the tires. The instructions here are provided to show you how 
to glue replacement tires to the rims in the future. Use CA tire glue, 
such as Traxxas Ultra Premium Tire Glue (part #6468). You can glue the 
tires without removing the wheels from the truck. For clarity, these 
instructions show the process with the wheels removed. 
1. Remove a wheel from T-Maxx 3.3 using the 

larger (8mm) end of the universal (glow 
plug) wrench.

2. Use your thumb to push the side of the tire 

away from the rim. Place one or two drops 
of CA glue into the opening and release 
the tire. Capillary action will draw the glue 
around the bead of the tire.

3. Repeat step two at four or five points around the rim, until the tire is 

completely secured to the rim. Turn the rim over and repeat the process 
for the inside of the rim/tire. Repeat for the other three wheels.

4. Reinstall the wheels, make sure none of the axle pins have fallen out from 

behind the hex hubs. 

Applying the Decals

The main decals  
have already been 

applied to your T-Maxx 3.3. The extra 
decals provided are die-cut for easy 
removal. Use a hobby knife to lift the 
corner of a decal and remove it from 
the backing. 
Carefully position the decal over the 
desired location and press one side on 
the body. Pull the decal tight and use a 
finger to gradually smooth out any air 
bubbles as you apply the decal. 
Look at the photos on the box for 
typical decal placement.
