you are going to need lift kit befor those tires will fit the runner

um, they're not going on the runner...

I dont have power steering yet arm stong only

i dont really understand the idea behing using BBs to balance big tires.  if you could explain a little what exactly it does that would be great.  my tires are bald as hell and i need new ones but i want to be able to balance them somehow and i have heard of this just dont know what it does.  thanks

How it Works .
The physics of how/why the free mass inside the tire automatically knows where to go is hard to conceptualize. The best way to understand why this works is to exaggerate the problem.

Imagine there is a 5 lb weight fixed to one place on the tire. When you spin that tire to normal highway speeds, it will be so terribly out of balance that the tire would probably hop off the ground with every rotation. The axis of rotation is actually moved away from the center of the wheel toward this extra mass because it's pulling the whole tire with it as it spins. The free moving balancing weights inside the tire are not affected the same way by these forces. First as you get up to speed, centripetal force will make the balancing weight stick to the inside of the tire. Then the force of the unbalanced weight on the tire will move this balancing weight away from the imbalance. When enough of the mass is opposite of the imbalance, the vibration disappears and the axis that the tire is rotating on returns back to the center.

To give you another example to explain why the balancing weight moves away from the imbalance and balances the system, think about what happens when you accelerate fast in a car. Anything that's loose moves to the back of the vehicle. This same force is created on an unbalanced spinning tire. The imbalance is jerking the tire sending the free mass inside away from it and the centripetal force holds it here.

it's kinda hard to picture your truck without boggers...

Yeah, it'll be kinda wierd, every Toyota I have ever owned has had boggers on it, this is a huge leap of faith for me, everyone says the Irok's are great, and they are a lighter tire, so I hope they work out.

if i am understanding BB balancing right, then basically the BBs just fill the spots that are out of round to make the tire spin evenlly?  how do you know how many BBs to put in the tire? just wing it and go with the same weight all around or what?

Here is the chart that tells you how many ounces for what tire size http://www.innovativebalancing.com/BigTirechart.htm

Basically the heavier side of the tire will want to throw faster, which in turn throws the BB's to the other side by way of centrifical force.

[toy4x4ota]

thanks for the chart. i think that i am kinda getting what you are saying, anyways i get that it works so im gonna try it when i get new tires

Got the pivot blocks welded in today (thanks Dave) and the bed cleaned off, that's about it. Seperated the damn driveshaft when the axle moved back an inch too far, so that gets added to the list for tomorrows work. Did have a beautiful drive home though.

[MiniSimp]

Everything went good today, I need a new power steering belt tensioner pully though.
Finally got the truck down to Tracy. Thanks Dave and Jeremiah.

[mickeyfinn]

nice looking pivot blocks. do they keep the stress the spring when flexing

[MiniSimp]

they keep the spring from stressing and twisting when flexing

fixed it for ya

[Duffil]

sorry I couldn't make it up.  Do you need the p/s pulley itself, or just the bearing?

Just the bearing I beleive, 19mm bore.

sure do have alot more room now  sure is lonley without MINI's truck here  probably never see him or the truck again

Please! Your wife is thanking me!

[MiniSimp]

Ok, so I think the transfer case might have been a little low on oil, looking at the lake under it this afternoon.

[*** YELLER ***]

your wife is gonna kill you  you better put a diaper on that truck       

[mickeyfinn]

fixed it for ya

thanks mini

i was just on the pirate site and was lookiing at your buildup there and noticed someone had gave you more information about a way to achieve better results with the BB balancing technique. once you get the tires mounted and balanced, post up how you added the BB, im really interested in this and want it to work as perfect as possible. good luck

Steveh gave me that info, I'm going to try it.

[MiniSimp]

The tires have been picked up for mounting and balancing!

[*** YELLER ***]

BUBBA he's got more tires than truck 

[locktup]

Your truck changes more than mine. Lookin good

I hope this is my last time.
