Tire Foams

After doing some web-reading one night, I came across two modification that wouldn't cost me any money and would help my RC get
better traction on the rocks. The two article's were:

"How To Cut Tire Foams" on RCUniverse.
"Rock Racer Tech Tips" on the Axial website.

I took the RC to the backyard after doing this, and what difference! I could totally see the added deflection in the tires and I was climbing
better than before. Not bad for a few hours of my time.

Here is how I did the work.....




Remove a tire from the RC and place the tire on the work bench.





Loosen the 6 bolts that hold the beadlock to the front of the wheel.




Remove the 6 bolts.




Remove the beadlock from the wheel.




Turn the tire over.





Loosen the 6 bolts that hold the beadlock to the back of the wheel.






Remove the 6 bolts.






Remove the beadlock from the wheel.





Separate the wheel from the tire, then the foam from the tire.




Cut 3/4" from the width of the foam.




Mark the foam as to where you want to cut it.




I used a bagel knife. It wasn't pretty, but it did the job.




The leftovers after doing all 4 tires.




Instead of cutting the tread of the tire, I decided to drill two holes in the wheel.




The holes are drilled 180* from one another.




Cut foams on the left, full foams on the right.




Sample of the extra deflection in the tire.












Cust foams tire deflection.




Full foams tire deflection.
