Not totally tractor related, had Winnebago Minnie 26BHSS travel trailer. 9500lb GVW. Bought it new. Had stylish 16” aluminum wheels and of course new tires. Stupidly think “It’s a decent name brand, no need to check tire or wheel ratings. They wouldn’t spec crap tires on a $35K camper with a name like Winnebago. Trust the engineers.”
First trip out was about 50 miles total as it was the shakedown run. All good. Second run was 250 miles out, 250 back. Check tire pressure pre-trip every time. About halfway back, less than 500 miles total, on a cool, rainy day the right rear explodes. Totally shreds to nothing. Pull off and see the tread is missing, sidewall is just a spaghetti of wires and rim bead killed by hitting the road. Change tire, pray we make it home (we did).
Start looking at tires and researching rims. Rims are rated for 1750lb each. Tires made by some no name Chinese manufacturer rated for 2000lb each. On a 9500lb GVW trailer that weighed almost 8000lb dry weight, well over 8000lb as outfitted and loaded when in use. Bad tires? Bad rim? Bad engineer? Maybe some combo? Regardless: bad.
Replaced all five (including spare) wheels and tires with black steel wheels rated for 3500lb each, shod with Kenda Loadstars rated to carry the full weight of the trailer. Have used Kenda Loadstars on campers, equipment trailers, and cargo trailers for many years. I’m sure they’d blow if I ran over a box of nails or something but thousands and thousands of miles without one failure.
Good trailer tires can be had, but the no name Chinese tires earned the moniker, “China bombs” for a reason.
I’ve heard from others that Greenball is good as well, but no experience with Greenballs.
And yes, I know Kendas and Greenballs are manufactured in China. Seems to be some quality control differences between them and the Fung How Ping Pong Co or whatever random folks make the no name stuff.
