of coz,claiming tire is problem for all brand tire i think.depend how u talk about problem or who u meet up?for me,i never been in claim tire so am not sure it really very hard to claim if new tire we just few week buy got problem like ....what problem u mean?
When doing tyre claim, try to do personally. No point going through the tyre shop or dealer. Most probably will reject.
If tyre have bulge go directly to the manufacturer service center. I think most of them have. I have been to the Dunlop one, long ago before Conti or Sime bought them over.
They will inspect the whole wheel, means tyre and rim. They look for rim damage, scratches etc. and tyre damage, like scratches, curbing etc. If nothing is found they will remove the tyres from the rim and inspect inside. In this case probably they will allow claim since cannot find damages.
They will then measure the lowest part of the thread pattern and that is your claim amount. Probably will issue you a voucher for you to change tyres at a dealer or tyre shop. Say if claim is 60% then you go and change tyres and pay 40%. If you don't like that tyre brand already, negotiate with tyre shop for other brands but ask them to make use of the claim voucher, then pay the difference....
