The Avon's are generally a softer compound tyre so the wear of the tyre will probably be more than say a Pirelli or Dunlop, however id say very similar to the Toyo's.
I found the Avon were a good tyre although ive never run them on the R, never had any complaints when i used to fit them to customers cars at ATS.
Obviously your choice of tyre comes down to cost, application, durability and overall performance. I will say this though, dont always trust what you see written as feed back or peoples comments i found it to be a load of terd lol.
