I just bought two Hercules H902 245/70 19.5 today as I plan to replace the steer tires. They are not installed yet as first available appointment is Tuesday.
Heavy tire, steel casing 14 ply. Build date is 0913 so they are fresh! There is a local construction truck rental agency here that runs Hercules on thier fleet of heavy trucks and they are happy with the results.
I did a lot of research and found lots of positive reviews. There were a few negative comments but all were from people that had no real experiance with the H902 but were prepared to offer a comment.
My experiance, other than buying them and bring them home is zero but for the price, $230.00 each, even if I have to replace them every five years I am still in the good! Based on the price you found I expect your tires are 22.5.
If my experiance is positive then I plan to buy two per year for the following 2 years and then all six will be replaced.
