Hooray for another tire thread! 3 pages and only 2 folks even mention Hercules tires (which was the OP's original query). They didn't ask for tire recommendations. If I wanted someone to skip the question and talk about whatever they want, I'd watch a presidential debate.
Hercules tires have been catching on lately in our area. A friend's family owns a commercial tire center, and they be been selling the fire out of these tires. Generally speaking, they're on the higher end of the China-made tire spectrum. Noting, of course, that being made in China isn't necessarily a bad thing.
To the OP, about 5 seconds is what it takes to run the "search" function on here, and it'll give you more info on Hercules tires than you'll care to read.
