The Redwood brand came stock with Westlake G tires till 2019 ( I think ) then they switched to 17.5 Westlake, then in 2020 to 17.5 GoodRide H ..
Over on the Redwood forums, there are mixed signals about the Westlake's, some have many, many thousands of miles on them.... Some switched to Sailun or Goodyear G114's B-4 having an issue.
I was one that was overly concerned with Chinease made Tires on my expensive to repair RV so I swapped to the Goodyear G114's... MAINLY because have a tire contact and get them at his cost.. if not and I needed to watch my payable for tires, I would go to sailun ...
The Sailuns are held to a whole different standard than those that mfg Westlake, and the others..
I do not recall off the top go my head what that standard is anymore, I once knew...
Note to self.. Don't let the computer spell check....its not as smart as me ! :B
