Heavy object on top of it? Personally and my opinion is reinforced by your justification above is that, this was a tyre categorised by inspectors as type c (damaged), not for distribution through official and legit dealers. There is another category type b (deformed), recomentation here is to be fitted in vehicles belongi to company fleets, for controlled use. Yes I understand that rases a hole lot of questions, controled use my ars.. excuse my language. Usually they sale those at a reduced price, presenting it as a publicity local campaign. Mark not an official first presentation worldwide campaign, where tyres are inspected one by one, and let me add for those of you with strong memory it was those first time presented tyres that were quickly discovered as faulty and oficially recalled two years ago by DUNLOP.
The common practise for type c is deferent unfortunately for us, dictates that is easier to big main importers and their distribution centre to get reed of such a tyre asap, what better than to sale tyre for 20-30 maybe 50 £ for any use, no importer wants to return tyre to brand for the recomented recycling, it's far more easier to sale tyre and delete fm the inventory , making a clear small profit, presenting only a 1£ worth invoice receipt that proves tyre was delivered for recycle to national recycling centre.
Common scam and really serves dealers and storage importers, brands too since they have less complaints, returns and more important bad publicity to deal with.
All the above make me very selective on tyre fitters chosed, never buy fm internet and never buy tyres on sale, even if they are fm a respectfully owner and are only older models .
"In two wheels we trust" to parafrace it.
