After a VERY hard time locating the correct size puncture-proof tires for my vintage kids trike, I am beginning to worry (from the stories I am reading) that if I attempt to boil and put tires on myself, there is a great risk of the tire splitting. What to you recommend? Should I attempt to install them myself? Is there a company you have used to install yours? Any info greatly appreciated. Located in NJ if you know any companies that would do an install out this way, but would even consider shipping if there is someone you trust.
