RE: Unglueing tires!!
Boiling tires is easy and works great. This is the method I use and it's NEVER an issue.
Fill a pot with water and turn the heat on it.
Next put a cap full of bleach in the water.
Next, put in the tire.
Now put the lid on the pot and let it come to a boil; once it's boiling it'll take about fifteen minutes for the tire to be ready to be removed.
Pull the tire out of the water and pull the tire carefully from the rim(use plastic gloves while doing this or you'll get burned).
Put the tire back in the water and let it boil for about 2-5 minutes again and then the other side will pull off.
The key to doing this is working QUICKLY once you've pulled the tire out of the water or they don't pull off as easy when it starts to cool.
Keep in mind this will ruin a chrome finish on a wheel, but it doesn't do ANYTHING to white, yellow, or other solid molded in color wheels. You can save some big bucks over time using this method. Tires and rims rack up some cost quickly, especially 1/8th scale!!
