Hi Paul,
I use a 3.00 x 20 block tread tyre on the back of my 2 Speeder. The first tyre was a VTS Brand which lasted about 4000 miles, soft rubber but excellent grip. I now have a Waymaster which is identical. This has done about 1500 miles so far. I cannot remember where I bought the Waymaster. On the Front I use a 3.00 x 20 Avon ribbed which hardly wears at all. Avons are not commonly available and Avon make batches from time to time. The Vincent Club may stock them.
