to me the damage is coming from the top side most likely. Look how curved the tyre surface is. Probably it collapsed on its own weight in a tighter corner (due to pre-existing fault or otherwise). It is obvious such tyre can be excessively stressed on a sidewall on faster sharp bends. = not fit for purpose
From rather unhelpful Goodyear response:
"
Whilst the sidewalls Efficient Grip Performance may seem more flexible which aids driver comfort, they meet the requirements for the EU casing and construction tests but also those of the U.S. where impact testing is part of the approval. "
In other words, yes they are too soft to be any good, but can still pass some old legal requirements.
" Should we during our inspection give an allowance (allowances granted are not an admission of liability) it will be % based and is worked out using the remaining tread depth of the tyre. We then advise the recommended allowance to the account holder by letter. A letter advising you of the results is also sent as long as your name and address have been included on the complaint form that dealers raise. If the dealer has no forms or electronic version on their computer they can obtain pads from the BTMA on 01787 226995.
The allowance will be made to the account holder who returned the tyre to us. It will be based on their purchase price of the tyre from us. Most dealers will then normally reflect that allowance back to their customer based on their payment price should of course the tyre or a replacement tyre have been brought from them. You will need to speak to your dealer regarding their complaint tyre policy and allowance reimbursement to yourself. "
This fails to observe sales of goods act. They are liable in full for this < 2 wk purchase, not some low %.
Guess which tyre brand I will now avoid like a plague, even though most other manufacturers also seem to offer some rather inadequate tyres (e.g Continental premium contact 5 is also way too soft). Its like camera gear where you have tones of useless compacts (canon and nikon included) and only 4-5 decent SLRs that can actually do something useful
Except I don't know which ones are the good 4-5 summer tyres for a regular car in 205/55R16 size...
Do potholes mean I need an SUV to go to work or local TESCO? It is on my list, but I can't quite afford one today, particularly after this!
