Wanting to change from STs to LTs..........

Goodyear allows the Marathon ST tires to run 10psi over the chart or sidewall pressure, which increases the speed rating from 65 to 75.
I am on my 2nd TT and they have been on both, lots of miles and rough road miles. I haven't had any issues I can blame the tires for, just 2 flats from rock punctures on some nasty forest service roads.
I will need new tires next year and will go back to the 225/75R15 Marathon in LRD, I max them out at around 80% of their load rating.
Many/some of "us" who had TTs in the past - also had Marathons.
They did just fine on my previous 20' & 24' Terry TTs.
(However, I switched to non-GY LT tires on the 24 long before I sold it.)
Many are/were aware of the GY 10psi "permitted" increase.
GY made that one disappear - although it still can be found out there in cyberspace.
That may have been about the time they lost the lawsuit, which included Marathons for RV use. (Google: "Goodyear kept tire problems quiet")
As already noted - 5th wheels and ST tires are *not* a good combo!
Since you are a TT guy, here's a lengthy thread from the Airstream forums about your tire choice..:C
Seems a lot of the Airstream TT owners do *NOT* share your warm feelings for Goodyear Marathons on their TTs..:(
It should be termed.... a *Marathon* about - GY Marathons!...:B

BTW it ran from 11-29-06 to 5-3-2011, then to a link for a poll at post #678 - which continues in a new thread with comments/posts thru 2014.
Apparently a "never ending" saga!..:R
Maybe you should post your success story there for a comparison..:@
