Crazy Crawler LaserFoam "HD Strong" 1.9" Foam Crawler Tire Insert (2) (120x48mm) (JConcepts Ruptures) (9.9 - 13.2 Pound Trucks)

The foam was too wide to fit the Traxxas Defender's tire without really blowing it out of proportion - so
I trimmed the insert, easily done. Then came the real issue - removing the tire from the wheel.
I tried the hairdryer method and found it was a real struggle. The end result - after a great deal of time
and energy - was the tire came off, but a small area of the tire's rim was torn.
For the second tire I used the bake method.
Tire on aluminum foil, on a cookie sheet in the oven, set the oven for 325 - no preheating,
the tire was in for the entire ride - then five minutes at 325 and pulled it out.
Very hot tire so wear gloves, but do not let the tire cool.
With a little force, the tire came off - within a minute - easily, without damage, and
without the hairdryer struggle.
Have your work area prepared and wear gloves that can withstand heat.
And now the tires do not compress anywhere near as much, and the Defender has more traction.
