Castle Rock
My new TT came with Castle Rock brand of tires. Some reviews say they are great with no problems others say beware. Guess very few manufacturers put Goodyears on at the factory.

I have two sets of Goodyear Endurance tires. For a given tire size, they have a higher load rating than other ST tires.
They also have a higher speed rating.
