Shocking deterioration of Continental tyres

Dear Sir/Madam,

I am writing to formally raise a complaint regarding the condition and performance of the tyres fitted on my BMW vehicle, which I purchased in September 2023. The vehicle is now just 22 months old and has been driven for approximately 28,000 km. Recently, I have experienced an unacceptable and concerning deterioration of the tyres — specifically, unexplainable tears in the rubber, which have progressed to the point of the rubber breaking off, leaving a dangerously worn tread of 1.6 mm. I booked my car in at BMW and was advised this was caused by glass pieces found in the tyres and suspension. I was advised by BMW that I must log a complaint with Continental as the tyres in question are Continental brand, supp**** with the vehicle at purchase. I find this level of wear and damage to be highly abnormal and unacceptable for a premium vehicle and tyre combination. I have taken the car to 3 tyre repair centre's for an inspection and was advised that no one has seen such on tyres before. As a consumer who has invested in what is marketed as a high-quality product from reputable manufacturers, I am deeply frustrated by this issue.

I logged a complaint with Continental and was told to take the car into a tyre repair centre which I did only to be told that my thread is too little for any compensation or repair to be done and that I must replace the tyres.

I was further told that this was due to me not rotating the tyres at 8000 to 10000km and due to alignment however my alignment report showed no issues.

This situation raises serious questions not only about product durability but also about the safety of the vehicle. Driving with tyres that have unexplained tears and dangerously low tread poses a substantial risk to both myself and others on the road.

I am formally requesting:

1. A **full investigation** into the tyre failure, including any potential manufacturing or design defects. 2. A **written explanation** from Continental regarding the root cause of this damage. 3. Immediate **replacement of all affected tyres** at no cost to me.

I expect a timely and satisfactory resolution to this matter. If no adequate response is received within 14 days of this letter, I will have no choice but to escalate the issue to consumer protection authorities and consider legal avenues.
