will a toe in problem cause a bounce

Not likely. More likely worn shocks, out of balance wheel or drum. Mismounting is a possibility too.

 

yes.

the outside will wear imto a roller coaster.

i had a 05 w9 that did just that, and vibrated and the same speeds.

i also had bad kingpins.

 

I have ran them for 22 years and seems they all do it to some extent some way worse than others , I had a wheel crack a few months ago and the new valve stem is machined in the face of wheel im sure yours is on the inside but I put centermatics on mine since I can now that valve stem is not in the way if it was me I would align it check all front end parts then leave tires on the same position and flip them on the rim , I know some of the super singles are out of round a friend of mine had them surfaced on the truck to make them round again sorta give them a hair cut is what the shop told him but he said after that was done they was smooth as glass till they were wore out ,hope this helps also they make different powder and bead balancing products personally they help but some times not .

 

I hear ya on the price I just bought 2 bfgoodrich for mine 755 a piece mounted what kind are you running?

 

the leaf springs won't do anything for you. unless they are sagging. shocks are what control the bounce. leaf springs. just look at them. see if they're cracked. all they are, is suspension. keeping the frame off the other parts.

you'd have to find out the ride height specs to measure the springs for wear. worn springs will cause the truck to sit lower. but that's not anywhere near an issue as shocks.

 

For the record toe in is very easy to check and two people can do it. Spec is 1/32 to 3/32. Measure from the middle rib of one tire to the other middle rib. The difference between the two measurements is your toe in or out. Sounds like you may have some toe out if the outside of your tires are wearing.

 

I would say most of your trouble is those tires I bough one set and never again bout shook the hood off I was able to run them out on lift axle , I bought them cause price was rite but paid out more in the end !
