wheel hop
i just put 38.5 inch tires on my truck and if you go over about 35 mph you get a VERY dangerous wheel hop. i mean its so bad it feels like the trucks about to flip, they are mudder tread. what would cause this? balence? shocks?

Is it hoping or shaking from side to side? I have seen wheel hop caused by a wheel that was out of round severly, worn out shocks and even unbalanced wheels. My Son had one that started hoping wildly and when we had the tire and wheel checked, the tire had about a gallon of water in it, and we have no idea how it got there!!!
I have also seen severe side to side shake take place that was caused by a bent wheel and some worn out drag link bushings.

My truck had a similar problem and what it turned out to be was the gears inside one of the hubs were damaged and caused one of the front hubs to lock in while the other was not. Did you check if your ball joints and tie rods are tight? Try putting the truck up on jackstands and spinning the tire. If it is as bad as you say, you should be able to see something wrong.

Big,
Are you hitting a pot hole or speed bump? Is there input to the suspension or is the wheel hop self perpetuating? Most big trucks do supplement suspension dampening when increasing lift and tire size. Go through the numbers and insure your front end suspension is as it should be. Inspect for bent or leaking shock and check your steering dampers for serviceability.

P.S. Get the front end off the ground to inspect it!

I just mounted the tires on the rims today so i dont think that there could be water in it unless there was a lot of water in the compressor. They are not balenced but i didnt think they would hop that bad if they wernt balenced. It seems to happen just on its own and somtimes if you hit a small bump.

I've heard of using water as a poor mans balance method before since it will actually help balance the tire at speed through centrifugal force or something

Yes, I've heard that one done to.
But tractors cannot go fast because the fluid for weight will come over the top of the rim, and in some cases throw them in the ditch. And that's below 30mph! So that's not the best way. I've also heard the spray-with-silicone-mount-drive-100mph way too.
Mike, with 38.5 tires you must have some kind of a lift right?
It could be a possibility you're not running enough shocks or too small of shocks to hold up to the added height of the tires.

[font color=red size=2]I would bet balancing the tires would take care of it. I've lost a wheel weight on my stock sized tires, and I get a terrible shake, imagine if it was a tire THAT big... I would got get them spinbalanced, they would also be able to detect a defective tire or rim. If it just started when you put on the new tires then it's something with the tires/rims.
