On a trip from Washington State to Michigan had GY670 outside rear blow out on our 43' Monaco Camelot. Had just replaced fronts with Bridgestones and should have put them on the rears at the same time but thought I could get one more trip out of the Goodyears on the rears and tags. Blowout happened in Spokane, WA area and couldn't get replacement Bridgestone tires or any other name brand in the size needed(295 80R22.5) for 4 days. Needed to get moving so had GCR tire put 6 Hercules on the rear which were in stock. GCR told me they were Chinese tires and I was skeptical about buying them but ran them all the way to Michigan and back with no issues. In addition, they ran smooth, quiet and cool the whole trip. They have great tread depth and look like great tires. The jury is still out but I like them so far and plan to continue to run them. Had thought about selling them on Craigslist when we got home but liked them so much that I decided to hold off and run them some more. Maybe I will regret it but, so far, they have been great tires.
