Everyone should "over tire" their trailers. My #7000 gross tires didn't make one trip. Moved to #10,000 gross tires and lasted 2 years. Now I have #12,000 gross tires and store the trailer on blocks with the tires covered. Cheap insurance................Good Luck
In our case it wasn't the tyre that failed
The first failure was when the wheel studs broke off the the trailer after axle had moved on the 100 mile dirt road leaving the lake. The second failure was when the 70's mag wheel exploded of the hub and took out the wheel studs, and U bolts holding the trailer axle in and flipping slipper type spring out of it's thing. It also pulled the skin off the trailer.
I sent the Rev off to retrieve the lost wheel, and apart from a bit of tread missing, i think the tyre would've gone around once more. However the wheel was in about five bits
So , we learned that Light truck tyres are good , and second hand mag wheels are bad.
Also if it it wasn't for Steve Barnett and Andy? convincing a the local car wrecker at Bordertown in SA that at seven PM on a sunday night when he was well closed and on his way out to an 18th birthday party, to sell him a wheel some wheel studs and a set of trailer u bolts, and a second hand wheel, and also booked us room in a local hotel, well me and the Rev would have had a tiring night asleep in the car on the side of the road
Thanks Steve and Andy.
