My lightest current trailer is a 7,000# car hauler with 205/75/15 Greenballs on it. Had Goodyears and after multiple failures in the first 2 years I switched.
My other two trailers are 9,680# and 15,600#. Both have 225/75/15's but the larger is a tri-axle.
I can not tell you how many sets I have put on for customers for trailers ranging from 7,000# to 18,000#. Safe guess is 25 sets of 4 or 6 since 2002 when I discovered them.
Not one single failure.
Goodyears and Carlises we had tons of failures with. Carlises were the worst and the Goodyear Marathons not far behind.
