That makes a LOT (2 words) of sense actually, I never thought my RE050s were any good but they were always low from when I bought the car. Having new Pirellis is a joy!
When do they need changing out, oh oracle of the north?
Before you lose confidence in them but before 1.6mm When do they need changing out, oh oracle of the north?

Age of tyres is pertinent as Bob says - JCT informed me that AM do not recommend keeping them longer than 3 years anyway due to the deterioration of the rubber - judging by the hairline cracks on my fronts they could be right 
Same for me - hairline cracks on all four tyres showed before the first MOT so they all needed changing. 13k miles.DB9 Ian P said:

Same for me - hairline cracks on all four tyres showed before the first MOT so they all needed changing. 13k miles.My wife has a Merc SL and at 4 years old we got a call from the Merc dealer telling us that all 4 of the original tyres were cracking, particularly on the inner side wall. Skeptical as ever, I went down to have a look and was horrified to see that the cracks were very deep and extensive. There were also some minor cracks within the tread. I had the tyres replaced immediately and when they were removed from the car, some of the cracks could be seen to be down to the cords. This car sits outside and had done 14k miles, with loads of tread left . The tyre manufacturer to their credit, gave us an allowance commensurate with the unworn amount of the tyres and whilst this was offered on a without prjudice basis, I was content with that.
I would not like to drive any car with cracking visible in the tyres, given this experience. However, if tyres start to crack at 3 years, I would be looking for a contribution from the manufacturer on the basis that they are not fit for purpose. It is also interesting that "new" tyres can be couple of years old when first fitted depending upon how long they have been in stock!
Why they were so bad on the inner sidewall was never explained but since then, that is where I look first!

Now here's a thought. Hairline cracks in the tires, could it be the sun? Is this common more on cars that do not live in the garage? Just a thought.
You little minx. You couldn't resist could you?I shall maintain my position that the UK is not an arduous market and that the cause of the hairline crack is nowt to do with the sun.
I would also echo Mr K's comment not to presume this to be an automatic mot faIl.

Agreed, but the last two winters in the UK have provided record breaking sub zero temperatures and a car stored outside would have certainly had its tyres frozen to the ground. Tiss well known, allowing that to happen particularly on petroleum based surfaces can cause tyre cracking.

Approx 15,000 miles and 6 pairs of tyres later :-)
Needles to say the car gets well used.
One MAJOR factor I find in tyre wear on an Aston is the Geometry.
Especially if you encounter a lot of rough roads with bumps, potholes or poorly repaired surfaces.
I find my tracking goes out fairly easily so I keep a keen eye on my edges for feathering and ramping.
Also after I had a full 4 wheel geo setup on my car I've not replaced a single tyre, which is great going for me, though I have to admit at the same time I had my Vredesteins fitted, which could go some way to explain the longer life span.

Under 3mm of tread the water channeling ability of the tread blocks is less efficient. You will definitely notice the difference in the wet....
My car gets used in all weathers, including torrential rain and snow.Even when lower than 3mm on tread it's perfectly docile with the traction control on, and I even used it with it off for a little while and it was nowhere near the handful that, say, a Griffith is
Granted, I do not drive as hard in the wet as I do in the dry, but to be honest even on barely used tyres you're asking for trouble if you do.
Changing that early is totally unnecessary IME. But YMMV as ever.
Incidentally, I tend to agree with Jockers. 3yr old tyres should not be cracking, assuming the car is used a reasonable amount. That said, I've previously heard that 5-6yrs should be considered the outside (my cars never go that long before the tyres are worn out
). The age of the tyre is marked on it - 4 digit code (if it's only 3 digits, the tyre is over 12yrs old!), first two giving the week and the last two giving the year. It would be interesting to hear from those getting cracks as to how old their tyres are...

Thanks for the info sMurph - if I think on I will have a look at the fronts upon my return and see if I can read the date of manufacture just out of curiosity. Jockman said:

If it says 235-40/19...... It means they were made at 2:35pm The 4th month (April) and nineteen refers to galactic years and means 2009...Hope you find that useful mate
