So I saw another tire failure on the highway today, that has been 3 or 4 in the last year , this one was in the middle of the 401 at the express lanes exit to collectors going to the Neilson/ Mornings...
The RH series have been out over 4 years and zero problems reported. I ran the RH 16" on my last 2 trailers for a total of 10k mi (traded trailers not tires). I wouldn't worry about them. I would have moved them to my new trailer but didn't want to pay for mounting(new trailer has 8 bolt rims).
