My comments are in reference to ST225/75-15 tires..
In 2000 I purchased a 25ft Prowler 5er.. had 225/75-15 Load range "C" Goodyear Marathons from the factory tires were made in late 1996,, ran them thru 2004, X 12k miles.. no problem.. In 2004 they were replaced with "D" Marathons.. another x10k miles without a problem..
2006 purchased a new Arctic Fox 24-5N with 225/75-15 "D" tires.. in 2009 at x13k miles all "no name" factory tired developed "goose eggs" in the tread areas.. all were replaced by Northwood's tire vendor.
2009 Dico (made by Titan) "E" tires were installed.. 2011 with x13k miles.. had first blow out.. more "goose eggs" .. had to buy a "C" bias when second tire failed in Key West..
2012.. four Carlisle "E".. one on way to Key West, three upon returning home (on bias "C") (Carlisle is what the agri-suply store at location of blow out sold)..
2014.. x10k miles on Carlisles.. will be three years old in spring '15.. they look fine..
all tires run at max pressure.. checked every morning (of a trip)..
ST225/75-15 tires are not of the quality that they were in the 1990s..
There is an LT225/70-15 "D" that is made for European delivery vans.. Continental and Goodyear make them in Europe.. sold by Tire Rack... these may be my next move..
BTW.. 16in tires will not fit under my trailer.. I have 31 in axle spacing..
Note:.. yes the LTs are 70s and the STs are 75s.. please do not criticize, offer a solution.. and remember..
