Getting a pair of 'new' front tyres fitted. A pair of Bridgestone Turanza's, £45 fitted/balanced, used, with 0.5mm of wear already on them - absolute bargain. Last time, I caught one monkey fitting knock on weights to my alloys (not this garage), so this time I asked to be sure they were using stick on's, but entirely forgot to tell 'em to leave the bolts just snug, and I would torque them properly.
At my last MOT, my mate the inspector, suggested the front one's were getting close, so I've been keeping an eye on them - down to 2.5mm so I decided to replace. What I hadn't noticed was the way it liked to wonder a bit, if I relaxed too much, behind the wheel. It felt fine, pressing on at speed, but relax and it seemed to like to wonder a bit. The 'new' tyres fixed it, and it now feels very precise.
I ended up in Lidl's car park later, heaving on a long bar, trying to undo them, and torque them up properly
..and, whilst in Lidl, Avril took a fancy to a VAX carpet cleaner, so we got one.
