    I found this blog after having a blowout on my travel trailer. Know the tires are bigger than what’s being discussed here but trailer tires is trailer tires. There’s enough info here about trailer tires that will make your head spin. In "theory" trailer tires are only good for about 5 years and then should be replaced. I know many are saying my tires are 20 years old and I haven’t had a problem. Trailer tires are unique in the way the sidewalls flex when turning which leads to premature failure. There’s also discussion about running them at less than the pressure stamped on the sidewall which leads to sidewall flex. IF regular replacement is done, running them at the rated pressure even though lightly loaded, there won’t be an issue with excess center tread wear. Anyway, just some random thoughts and enjoy the reading.
