the trick with glueing 4wd fronts is to take your time. i have done mine for long time now. i start out by cutting the rear tire down middle of the tread. figure out how many pins you need to cut out of each side. make sure you do the same on both sides. using straight body trimmers cut each side evenly. now comes the fun part. what probably works best for glueing them back together is take a penny or something simular and apply some ca glue to it. take an old x-acto kinfe and dip it on the glue. apply the glue to a small area on one tire. now hold the two pieces of tire together and let dry. then continue around the tire doin just a small area at a time. this process takes a while to make a pair but it is how you have to do it if you have to run a certain set of tires. sorry i dont have any pics of how to make them but if any more questions let me know.
