Prometer tires - anyone know them???

[Vladivar]

I contacted my local OK Tire about swapping the Castle Rocks on my Rockwood Sig 8324BS to the Goodyear Endurance (225/75R 15) based on reviews and comments from other users. They came back to me with a price, but also suggested I look at the Prometer ST (same size) which they can supply at $670 installed vs the $915 for the GY (Canadian $). Problem is I cant find anything on the Prometer tires as far as reviews go.

Anyone??
