The rear tyre question is interesting. It seems that the factory are fitting whatever they have in stock, not one tyre in particular that has been honed for use on the Three Wheeler.
What is really needed is a soft compound rear tyre, giving plenty of grip, but for our low miles, the wear isn't particularly important. From my experience with Caterham Sevens I know that the Avon CR500 is just such a tyre, and they do it in the right size too. The trouble is, as I'm such a wimp, I haven't done enough miles for any wear to even show yet, otherwise I would've changed to one. If someone else is looking for a sticky rear tyre, then try the Avon.
