Duravis R250 or M895?
Hi Team, Getting ready to replace the tires on my 5th wheel. Looking at both of these tires. They are both fully steel encased. Both seem like Great (and very similar) tires. Do you all see any...

Hi Chris,
I agree with most of your sentiment about ST tires and that is why I upgraded to 16" Duravis R250 tires from my 15" ST. I have been towing for a while and own several trailers (11 axles of ST tires, total), so I've seen my share of ST tire failures and have been a student on this forum and other forums of other tire failure stories. My experience is that the ST tire lamination process is unreliable for our heavy trailers.
This said, your exclamatory comment to me was that I must not have compared the R250 specs to the ST tires. Since I'm talking about sidewall stiffness here, my question to you remains what data do you have, which you think I didn't compare, that shows the R250 sidewalls are stiffer than an ST, Load E, 10 ply tire? I'm not doubting but asking for the data/info since every manufacturer's website that I have visited, including for LT tires, cite the stiffer sidewalls of the ST tire, when compared to an LT or passenger tire.
mrw8i - Not sure who your question or comment is directed but if it is to me, yes I do have three engineering degrees (not up to PhD just MSME) with a heavy emphasis on materials science in my engineering career. Doesn't make me a tire expert by any means! but I do understand mechanics and physics pretty well. For technical stuff, I typically do not put a lot of faith in much of what I read in a forum or on a manufacturer's website unless I can validate the info/data from other sources.
Thanks,
Phil
