Hi Bob, Thanks for your reply. It was really useful. Thinking through the arguments a bit more, I think you have come to the correct conclusion. In fact, I have ordered the Uniroyals from Black Circles today. This gets me over an immediate problem.....my AO21Rs were shot (6 years old) and had the grip of blocks of wood. I have a track day coming up May 1st, and, although not that 'racy' the Uniroyals should be ok for that. More importantly, We are also off for the IOW Blat soon, so they will be ideal for this. I too think the R888s look good and are popular. The tricky thing for me will be the selection of wheels to go with them. I have a live axle so the studs need to be Ital/Triumph pattern - I don't know how easy these will be to find. Anyway, thanks very much for your reply, I found it really useful and have followed your strategy. regards, Nick
