Panda Multijet Tyres

Just been in for the check today and had it in for 2 hours. This time they reckon the tracking was out and have adjusted it accordingly. They reckon the 4 wheel tracking test wasn't required after all as for the rear wheels to be out would mean the car was twisted..hopefully not the case.
So, now to source another couple of tyres and hope that's the end of it.

Price for the 2 hour check, £40.

I've only done 6k on my tires and they're already starting to wear rapidly. I do get alot of tire squeal when cornering as there are lots of bends here and you have to take them fast in order to get anywhere. I don't think the standard eco tires are as grippy or as durable as other makes. I had similar sized tires (155/70 R12) on my first car (perodua nippa!) and they only lasted 6k miles, i was expecting the Panda's to last about the same!

Anyone found tyres that run quieter than the Eco as mine on 1.2 are really noisy on chipped stone tarmac & it's worse now the tyres are wearing a bit.
I think the low tread profile & rubber/plastic mix they use to reduce friction is
what causes the noise
