Oh good, a puncture.
It's been a while since I used a standard jack - so frequently using my 3T high-lift trolley job, I'd forgotten that the standard jacks are absolutely rubbish.
This puncture is right on the shoulder of my (already oddly-worn) potenza, so two new ones tomorrow or Saturday.
It's a sad case that I'm resigned to a day of phone calls, trying to get someone relatively local (I'm in Exeter at the moment) to pricematch Micheldever or Mytyres, just so I can get a pair of S03s (to match the relatively new backs) for less than three hundred quid...
Must also remember to get the tracking checked again, don't want another pair of tyres going down the drain!
