Hi Larry,
I have done a bit of research and it depends on who it is writing comments about the tyres and their competition. There are some who will say that they are not as good as Dunlop, Michelin or Pirelli but compare well with Avon. On the other hand the Piston Heads website is full of praise despite a couple of reservations. None of the comments or reports related to their use on Tractions so it is difficult to tell how suitable they may be. The cost of five tyres and inner tubes is £870.00 and they are made in Indonesia using the most up to date methods apparently.
