PVC is a little too slippery to be used as a drift tire. They do work, but the car speed is extremely slow and contorl is sketchy at best.
Much better is a slightly different type of plastic piping called ABS. This is softer and gives you better bite whilst still breaking into a slide very easily.
You should be able to find pipe with a similar ID to the dia of your touring rims.. just slide them on (chuck some electrical tape on the rims to increase the "hold" if needed) and you will be able to slide them off when worn..
There is a drift thread already so check that out...
