But I did find the problem, the front axle was bent and I replaced it. Now it tows smooth at all speeds. Older rubber is harder and will slide easer and new rubber is softer and will grip more so if axle is bent alittle new rubber will make it more pronounced and cause it to hop.

I never saw that til I went to work for the guy I now work for. I'm starting to get used to not having to patch things together to get through the season. Dad would have had my hide if I had a service call for a hydraulic hose. [Reply]  [No Email]

I went from 700-14.5 to 800-14.5 They are made in China, which I did not know until I received them. The company name was tires USA so I thought I was getting a quality tire. Live and learn. thanks again, Dave [Reply]  [No Email]

Unless it is a HD tandem dual beaver tail. Then it would be about a 30,000 lb trailer, probably pintle hitch. Could be the heavy MH springs. CT [Reply]  [No Email]

My friend was pulling his 560 one day and thought he felt a vibration, checked his tires when we stopped for gas. Followed him about a mile down the road and got him pulled over, a tire came apart that fast. It had no visible problems at the gas station, and when I got him stopped the tread was separating, and the cords were all broken. It's a wonder it didn't blow up when we threw it on the deck.

Two or more tires are traveling in slightly different directions. When they get a certain amount of side pressure on them, they lose traction and *POP*, the trailer jumps into the air like a tiddly-wink. [Reply]  [No Email]

I have a double axle trailer with house trailer axles. Brakes on all four wheels, new tires, two tire shops to try to balance. Loaded no problem. Below 35 or above 40 no problem.It doesn"t take long for me to speed up or slow down! I have owned the trailer for some time. It was like that when it only had 2 wheel brakes and old dry-rotted tires. I carry 90lbs in each tire. Under inflation with a load is NOT good. If I were making an empty long trip on slow roads ,I might consider dropping pressure to 50#? Otherwise I just adjust speed accordingly. f [Reply]  [No Email]

Got home, replaced tires and solved problem. Good luck. [Reply]  [No Email]

If a single axle, the axle could be bent. A tandem, could be either a bent axle, or the two axles are out of alignment. [Reply]  [No Email]
