Lyle... I agree... probably just marketing. I am nowhere near
the 5ver GVWR (14,300) CAT has me at 12,600. So, I'll stick with
the same 80 PSI I have run for the past 4 years. It hurt to remove
the Marathons with all that good tread left, but, the sidewalls
looked like it was time. Cost of doing business.
Chris... I honestly did not look into the Bridgestones as the
Ribs seem to get "most favored nation status" on this website.
If the Carlisle's don't hold up I will re-evaluate. Thanks for
the recommendation. It is funny, before I became a forumite I ran
my previous Monaco Medallion 32 ft. travel trailer for 10 years
on something called "Contenental" tires... never had an issue.
Ignorance is bliss ! ;)
