They are radial tires. 10.00R20. Thanks for replying!

Hello, I just bought this tandem dump truck. I haven't owned one like it before. But when I picked the truck up the tachometer worked. Somewhere along my 2.5 hour ride home I noticed the tach was sitting at 0. When I got home I pulled the cable, spun one end and could see the other end turn. That leads me to think the cable is okay. I plugged the governor end of the cable back in and started the engine. The tach end of the cable was not spinning. So this leads me to think the issue is in the governor, or maybe the cable end, which was not the square like the tach end. It had a round piece of black plastic on it which I could slide off the cable, which looked like it had a couple of keys along the sides of it, if that makes sense? It is possible they may have been sheared off because they didnt stick out from the sides of the plastic piece. I guess I should take a picture... Anyway, does anyone have any ideas what I should be looking for to get my tach functioning again? Thanks!

Hello, I have a 1977 R685ST tandem dump. I just bought it, got all the paperwork done, drove 2.5 hours to pick it up, left where I bought it from, got up to about 30 MPH, and I was pretty sure something was about to come out from under the rear of the truck it bounced so hard. I stopped, looked around, again didn't see anything loose or bent or broken. So I got back in the truck, started off again, less than 30 MPH it might have shook a little but it was tolerable. Got back to 30 and the truck shook like the end of the world. I decided to see if I could go faster and make it go away, and it did. So luckily my whole ride home was mostly highway and at 50MPH things weren't too bad. I do know the truck had done a lot of sitting before I bought it. Like a couple years' worth. Could this be a flat spotted tire or 8? They are 10.00R20. Could the wheels be that badly out of balance? They are Dayton wheels. Is there a way to balance these? Anyways, thanks for reading. Any advice would be appreciated.
