What you want / need are the control Lilac tyres.
However, they seem to be rarer than rocking horse poo at the moment, as I'm looking for some too!
If you get new, you need to true them down to 56mm for best balance between grip and life.. wear is low and by the time you wear them out you'll be somewhat older. I run mine almost every week and have used 2 sets of tyres in 18 months, but I do go down to the plastic...
