I've been wondering about this largely since issues with tyre noise got me thinking about the tyres on the car.

I bought it from a main dealer. The service history showed a long life service after two years and 16,000 (ish) miles. A year later, it had been serviced again at 23,000 (ish) miles. Seems OK - average of about 7,500 per annum by first owner who had the car from new until first MOT.

But how do you explain this mish mash of tyres that were on the vehicle?

1) Front axle, two Michelins. Actually quite worn and I replaced after another, 2,000 miles.

2) Rear axle, two Goodyear NCT5s. Down to about 5 mm. One tyre has uneven tyre wear on the outside edge.

After 23,000 miles, I would expect the car to have all the original tyres. If the front had been replaced, they would surely be almost new? Or, at the very least, allowing for putting the best tyres on the back, at least two of the tyres would be nearly new?

Everything else stacks up but how can you explain two different tyre makes on a 23,000 car, none of them anywhere near having a full tread?

Do dealers routinely take decent tyres off cars?
