...One of the best kept secrets up north is that the Hercules Avalanche RG2 is not just similar to a Nokian Hakka R, it IS a Nokian Hakka R, made using the same molds in the same factory. It's just the older model after Nokian moved on to the R2. Hercules bought the molds for cheap and continued production.
Maybe the two tires are different. Some talk is that Douglas tires are made on the same equipment as Goodyear tires. Now for my story:
I splurged & bought some Goodyear Assurance tires(my first time) & I love them for their tidy handling & what looks like they'll get 60,000+ miles. Altho I got an excellent rebate(quickly returned, too), they still cost $650. I was so blown away by the final cost(hidden in the beginning), I started buying used tires. I have some used Douglas tires now. But, touching & comparing them to the Goodyears, you can tell they are different. Reviews of Douglas tires are generally completely different than reviews for Goodyear tires.
