Well tonight could have gone better!
Driving home and suddenly noticed a massive vibration coming from the rear - I was only doing about 15 mph but every time I accelerated at all it started shuddering and vibrating. Pulled over and found the rear left tyre flat.
Of course the Ion like many modern cars (and all EV's to date) has no spare tyre, just a tyre goo inflation kit, which annoyingly is stored under the rear seat, which meant removing Joshua's baby seat (luckily I hadn't picked him up yet) to then remove the base of the rear seat to get at the kit.
I tried the goo but it didn't work as the puncture turned out to be quite bad, so I phoned the AA, not really knowing what to expect as I've never called on them before!
The guy arrived in under 30 minutes, first had a go at repairing the puncture with a proper puncture repair kit, but it was too severe, we then arranged to get the car back home rather than try to take it somewhere for an on the spot tyre replacement, so he put their universal spare on the car and followed me all the way home before collecting his spare. I was very impressed with the service and it certainly got us out of a bind!

We were then able to transfer the baby seat to the Xantia and go pick up the little boy, albeit 2 hours late.
I now have a little bit of a dilemma, the two rear tyres and one front tyre were all down close to the legal limits, are a bit cracked and are only summer tyres, so I had already planned to replace all 4 with a set of all seasons before the winter as we can't afford to be without traction in the winter trying to get to work...
However I wasn't ready to replace them just yet. I don't want to put a single cheap summer tyre on to get it going again and then have to replace it again in about 3 months, nor do I want to put a single all season on the same axle as a worn summer tyre - that would be a recipe for disaster! Or at least a recipe for lots of wheel spin thanks to the torque of the electric motor. (I could already spin the left rear wheel when accelerating on a tight bend)
So I think what I need to do is fit two new all seasons to the rear now, (remembering it's rear wheel drive) and then fit two all seasons to the front in a couple of months before the winter comes around. I wouldn't normally mix summer and all season tyres, but I think it should be reasonably safe to have the new "better" all season tyres on the rear, temporarily ? It already has skinnier tyres on the front to induce safe on the limit understeer even though its rear wheel drive, so this would just make it a bit more understeery.
The next question is what to get... because I need to get a type of tyre that is available in both front and rear sizes as I'd ideally like a matched set later when I complete the set. The sizes are:
Front: 145/65R15 72S
Rear: 175/55R15 77V
I know some suggestions were made a while back in this thread I think but a quick search didn't turn them up.
Technically speaking they also should be low rolling resistance tyres on an EV, and the original factory Dunlops are low rolling resistance, but I'm not sure how much difference it really makes to the range!
I'm hoping to order them tomorrow or Friday and get them fitted on Saturday. While I appreciate having the Xantia as a backup car the petrol cost will see me broke on our daily commute unless I get the Ion back in action ASAP.
