I thought this was a good thread from the old forums. Gives people some advice on what tyres to choose for the skids.
Here is what i use:
Front - 185/60/14 Bridgestone RE001
Rear - 185/60/14 Nankang 611
I find the nankangs provide grip and they last for a while. I've only had one delaminate so far (out of about 10) because i forgot to swap them left to right. But yeah, i rate them.
