Easy-to-make Super Swampers (Big Tires)
 

This tutorial allows you to make a pair of bigger tires for your crawler, that are bigger than the ones included in the lift kit. You'll need the following...

The rims from the "Slammed Rims and Tires" for the truck
(The 6-Spoke black rims if you don't get the message)

The tires from the "Lift Kit" for the truck
(In other words, the bigger tires that say "Mud-Terrain T/A and "BFGoodrich")

Now, take your rims, and simply push them into the tires and the tire should stretch, causing the tire to get bigger.

Bolt them onto the truck and you're ready to climb!

However, it is a nice write up.
If it weren't for the two things mentioned above, I would congratulate you on a well written tutorial.
And for future reference, people always want pictures with their tutorials.
