"Rv Travel", a weekly emailed news publication, surveyed their readers last year and found that only 47% of the 1800 or so respondents, actually knew their "weights". And I believe many of these folks are full-timers or nearly full-timers!
After weighing our truck and fiver at a certified CAT scale, and being very surprised with the actual weights compared to those from the factory, I have a theory that most tire failures are because of inadequate tires for the loads of the fivers. Most people are careful about their psi's and watch the tire temps, but the tires are often just not sufficient enough to carry the loads placed on them.
I changed to GY 114 "H" rated tires 17.5" from the factory "E" rated Duros. The new tires were "fresh" (manufactured within the last 4 months) and will be replaced in four years regardless of the tread condition.
The CAT scale weights really startled me because we don't have the fiver "overstocked", but our fiver is near capacity for CCC. Good luck. amf
