Continental SportContact 6 UHP Summer 275/45R21 107Y Passenger Tire

I would not recommend these tires on the fact of how loud they are! From the day I purchased the tires, they have been ridiculously loud. It doesn't matter if I am driving on backroads or highway (which is EVEN WORSE!). I need new tires already and it's only been 46K miles since I had the tires. For the amount of money it costs to purchase tires, I should be able to drive close to the warranty's suggestions of 60,000 miles. Very frustrating it's been 2.5 years since I purchased 4 new Celsius CUV tires. They are decent tires in the snow and rain, but the noise factor out weights the pros.

Celsius CUV Tires on a mercedes Gl SUV. Shocking is that overall ride poor as 2 of tires caused instability during first month of installation. Totally unexpected. Later at speed needed to restrict speed to 50-55 mpg (lower than 100 kph). My hope is that TOYO would examine tires as it may help with identifying an issue in manufacturing or tire casting. The 4 toyo tires were replaced. My SUV is back to driving flawless at all speeds.
