I purchased an approved Honda Jazz from at a main dealer in May 2016. At the time, I pointed out that both the rear tyres had sidewalls that were quite worn and rough looking. The salesman said not to worry because the warranty would cover it. I have now had a puncture at the rear and, after removing a small nail from the tread, I used the temporary repair kit. My local Honda dealer stated that they cannot repair the tyre, although repairable, since the sidewalls are worn and advised fitting a new tyre immediately, which I have had done. The car has covered 3000 miles since the purchase date, one should not be liable to replace the tyre due to a puncture that is repairable, after such a low mileage and after the reassurance by the salesman. Please advise how to make a claim.
