All good mate, I've been pretty flat out myself organising a wedding, bucks night,getting married and all that other $*#!.
I decided to go to my local Dhz dealer and got a very aggresive looking Vee Rubber tyre! never heard of it before but he recommended it over the Kenda, same price too. My mate recons it ****s all over his rear Carlsbad. Just not sure how long its going to last.
Again thanks for your help mate.
