So you are saying that the Goodyear G614RST (an ST tire that is very much raved about on these forums) is not a quality ST tire.

You seem annoyed, so bashing comment aside, I'm just trying to educate since you've asked. There is no quality ST tire like an XPS Rib or Duravis R250 (or G614).

The "raved" Goodyear G614RST is actually an LT tire with a speed rating of 75mph, not 65mph like ST tires, and follows the standard inflation tables.

It would be a great choice of tire if, your rims can handle the pressure, you can find a size, and you can choke the cost.

My money is still on the Duravis. It's obviously an easier choice for me since I'm at 18k, but I'll point out what most people don't when looking at tire loading. Even if you load to 21k, in my mind you should be able to subract the weight of the pin on the truck (3500ish?) for actual trailer axle loads...even if the manufactures don't allow you to do such for the coach numbers. That's putting you around 17,500 on your triple when loaded to the limit.

Your best bet though is to stop asking everyone else and go weigh you rig. Then you'll know for sure whats on each axle.


Good luck with your choice. The GY's are a great tire too.

Thanks for trying to help Hemi.
I think it is fair to say that I am frustrated. But I do appreciate the help. Please let me be clear. I have weighed my trailer(loaded). I don't have my cat scale ticket with me but I'm sure I was less than 17k(trailer) Probably 16.5k. Also Please note my MAX GVW on trailer is 18K, so I can't load to 21k. My problem seems to be that it has Dexter 7k axles(I don't know why). According to what I've been reading- tires must support the axle's rating of 7k. The RIBS & R250 don't do that. I do have wheels stamped at 110psi. So if I understand my research correctly I have 3 choices- 1.) stay with the dreaded ST's 2.) upgrade to 17" wheels, or 3.) go with G614 ?
