Hi,
My Marina would be at the end of its theoretical extended warranty on 28/10/2009. Apollo launched its Acelere tyres just before I got this car. Somehow I wanted to try these tyres and so along with the alloys from the showroom, it was arranged with the Tata dealer to have new tyres replacing the original ones. So I never saw the original tyres (Bridgestone ones) that came with the car.
I was quite happy with the tyres. I developed this idiosyncratic notion of not rotating my tyres since I had the Indica (did not work out the way I expected as I lost one of the tyres due to damage). I have continued the same with the Marina too. Is there a ?divine conspiracy against me, I don't know.
Eight months into the life of the cars and tyres, it had a rare out of state trip to Bangalore. Approximately 11180kms and the right front tyre had developed a 'weight' problem - a nicely rounded bulge. I drove with it back to my place and at 11923kms switched the front ones to the rear ones. With Apollo refusing to havea nything to do with the misfortune of the tyre (I have hence understood that tyre companies hardly have to honour warranty claims), I was forced to use that tyre with a tube as the stepney and put the 'until then unused' stepney on the right rear to go along with the older left rear. This was on 24/06/2006 with the odometer reading 12220kms.
On 04/06/2007 at around 24250kms the left front was turned inside out for an inner side wear. At around 35000kms, the front tyres were ready to be changed and an imminent long distance trip precipitated the change. New tyres were put in the front - JK Toronados of 165/80R14 - thereby undersizing the tyre. This was done on 24/12/2007. The left rear had a puncture also. This same tyre had more punctures and the latest was on 19/07/2009. This tyre was pronounced as 'unusable' by the tyre people (it was also worn on the innerside) and so for the present my 12220kms run 'bulge with a tube' tyre is doing rounds on the left rear side.

This place was blessed with 2 punctures already and this was the third puncture. It also has developed cracks / cuts. Nothing on the inside that I can see.

This was closeby and again nothing inside the tyre.
So on 20/07/2009, the longest running tyre of my original set went into a little premature retirement after it covered just 58747kms.
The JKs in front (our roads and improper attention from my side in taking care) have worn in so many different ways and will need change soon.
To continue with my idiosyncratic ways, I invested in the same JKs and is the stepney now as I have to get my suspension alignment corrected first before doing any new tyre changes. With the recent 'unhappiness' with my regular service centre, I am thinking of finding another non authorised service centre for my next (60000kms) service.

The one with the bulge - 12220kms old

The one doing duty since 12220kms (so is 46527kms old)
The second one if it does not face any unnatural conditions should be good for quite a long time.
