Special Trailer (ST) Speed Rating

[red.jimbo]

My TT has Goodyear Marathon tires. While researching for another thread, I stumbled on this notice posted by Goodyear on their website.

I somehow don't think this data is specific just to Goodyear trailer tires based on how it is worded. They make it pretty clear. If I am going to run my tires at their maximum weight rating, I better keep it below 65 mph!

I don't have a question. I just wanted to share this for our mutual edification.

there seems to be a catchto this. The document states: " when used under normal load" conditions. If you look at the actual load rating for the tires, each tire can just about handle the GVW of the entire vehicle. I think on my camper each tire is rated to handle about 2/3 of the GVW.

So the question I pose now is: Since we are not running at the rated load of the tires, does this speed restriction apply? In a worst case scenarios, on a heavily crowned road with 1 tire blown out you could argure that you are getting close to that 2/3 GVW on the remaining tire if it's on the down hill side.

I just looked at my tires on my 8280SS. According to the specs(yes I know they are mostly fictitious) my trailer has a GVWR of 7868 lbs, and an axle weight of 5240 lbs. Now, my new Trailmaster ST tires have a max weight rating of 1820 lbs each. That seems to indicate that if my fifth wheel is at max weight and I blow one tire, the other three are just shy of their max weight. In reality, the one next to the blown tire is now overloaded.

I was running about 65 MPH and it took a good minute to work my way to the shoulder. (6 lane wide beltway around DC)

The aft tire was "squashed" but did not look "ready to fail"

I am sure if I had ignored the "pop" and hoped it was some one else, (There was no other indication), the outcome would have been very different.
