2k Miles : Slow puncture, repaired (£10)
4k Miles : Slow puncture moving onto a blow out, new tyre (£130, conti sport no mitchy's in the UK for love or money !)
15k Miles : Slow Puncture, non repairable, new tyre (£150) same tyre that went at 4k miles

15.5k Miles : 2 fronts on the markers, new tyres (£300)
So after 15.5k miles I have spent £590 on tyres !!
I put one set of rear tyres on the liz at a cost of £250 iirc for that sort of mileage !!!
