“Tire Size 270/50 R 20 Tire type: Cooper Discover SRX These tires came with my 2021 Brand new Mercedes GLS 450. I bought this car in May 2021.

I had a few bad to worst experiences during wet weather conditions. I took my car for my 20K service milestone; My Mercedes dealer acknowledged worn-out tire condition; advised me to purchase new tires. They never informed me about warranty replacement. I just got my tires replaced with non- cooper brand. …”
