Depends on how many miles you have on them. If you do get repaired, make sure to use a plug patch applied from the inside of the tire.
How much do you want for them?Thanks for the reply guys.
I think i've made my mind up to change the tyres. It came down to confidence level, although I'm content with the Supecorsa's I'm not a 100% confident with them, especially on a cold morning! And with the added niggling thought of a plug, i wont enjoy the bike to its full potential.
I've only done 1000 miles on the tyres, and the front looks great.
