We have had B F Goodrich ST230's for over 5 years and have put over 60,000 miles on them with no problems. We replaced the original Toyos on our '04 DP. My husband is a former "tire guy" and complained about the Toyos cupping and bad ride. The B F Goodrich are a much better ride. We will replace them with more B F Goodrich next year. As you say, they are owned by Michelin and made in the USA. They were recommended by Pat at Pro Tire in Denton TX who has replaced many RV tires up to and including Prevost coaches.
