After much searching online for a set of replacement tyres, I settled on Nankang NS20 Sportnex - 165/50 R15 72H TL for £39 per corner. Camskill charged £15 for the delviery for the set. I have to say the the ride is much improved compared to the NS2, so maybe a little softer due to the age of the old tyres, grip in wet and dry seems perfectly good but then I can't say i really push it. No noticable increase in tyre noise or fuel consumption.
