Does the problem persist if the tires are returned to their original position?

Static or dynamic balancing wouldn't detect the contact patch of the roadway or if the wheel itself was bent/warped. Unlike the front end, caster and camber aren't an issue on a live axle.

Assuming there are no modifications to the suspension, is there any damage to the leaf springs or shackles/bushings? Is the axle splayed in any way? Seems you would be using the same struts, bushings, and dampers that were just fine before the tires were rotated.

Let us know what you find.

Got a tire on the front now that needs road force balancing. In a perfect world with no out of balance what so ever, you can get by with worn shocks/struts. New shocks or tires will fix it. Don't know how many miles on it, probably due for shocks anyway. Could put the tires back (mentioned above)

Bought a used Tundra years ago, right away the ride was questionable. It came with larger tires, 3/4 or so worn. Some new Michelin tires took care of most of the issues.

We can ‘assume’ your wheels themselves are ok? The ride was good before rotation?

Yes, I noticed nothing prior to the initial rotation. < 1 year on these Cooper Discoverer ST-MAXX tires, so they are well in the green on tread.

I have no suspension modifications as of yet. I'll try rotating them again if I don't find anything else obviously wrong with them. I'll inspect the struts, too.

Are your tires directional?

Just give the truck a shove by the front fender.

If it moves any, they're bad.

Yeah, Also if the tire was not properly indexed on the wheel when being mounted, it can be balanced, but not round.

Wouldn't affect drivability when placed on the rear, but move it to the front and it would be a lot to hold on to when harmonics kick in at speed.

Tires are not directional. No abnormal movement noticed on the struts and no mud chunks. All were at 35 +/- 1psi. The wear on both looks just like this one. It is very even across the tread.



I just had it up on jackstands. The bearings have zero slop. I didn't notice anything in the suspension. I DID notice this difference between the front wheels:




Notice the one above with all of the extra weights is missing those flat, square factory weights? Is it normal to take those off as needed? I thought those were on there from the factory.

The stick on weights on inside of rim are just an alternate method of adding weights.

If you have long strips of wheel weights, the tire is mounted wrong. Look for the yellow circle on your tire) it indicates the lightest part of the tire). It should be aligned with the valve stem

If you took a tire depth gauge to the front and rear of those outside blocks, you will find wear, they look feathered to me. That would be your noise.
Weights are used on the outside and inside of the rim. That particular rim wouldn't take kindly to trying to drive weights on the outside edge, so they use adhesive weights on the inside of the outside edge.
The adhesive weights are a pain when the rim is dirty, takes some time to clean everything up.
Can go around discussing it but either put them back or road force the fronts and put struts in it. But this is a gun forum and nobody knows nothing about auto repair .

When I rotate my tires, I use a tire gauge and measure the tread depth four places across and at least three places around the tire. That way I can see if there is even wear and I record it in my maintenance book.

The last set of Michelin's got 117K miles.

Sorry, but those tires themselves look a little questionable. Before chasing with a bunch of $$, I’d get better tires.

This wheel was on the rear and is now on the front? There is nearly half a pound of weights on the inside, and I don't see any stick-on weights on the outside, just the remnant or residue of the adhesive. If this wheel were to be put on the balancer and spun before removing the weights - something I often did when diagnosing problems like this - I'll bet it would show considerable out-of-balance.

^^^That's a crap load of weights

Absolutely a crap ton of weight to try to balance that wheel/tire combo. There is definitely an issue with that.

I don't know what kind of balancers Discount uses, but today's quality wheel Road Force Balancer will detect any out of round wheel, improper mounting on the wheel balancer itself, or wheel/tire positioning (heavy areas of both wheel and tire not being offset from each other). There is a possibility that the tire itself has internal damage that you can't see such as a belt separating inside the construction of the tire.

Some of these issues can be masked when the wheel is mounted on the rear of the vehicle, but become obvious then mounted in the front.Also as some here have stated, suspension wear needs looked into as well, but that amount of weight on the inside of that wheel needs to be explained.

Rotate the tires back to the location where they performed satisfactorily.

This one is a little better, but still not very good. There appears to be 2½-3 oz. on the inside, 3 oz. on the outside (each segment of the stick-ons is ¼ oz.), a total of ~6 oz. This much usually indicates an out-of-round (up-and-down motion) or runout (side-to-side wobble) condition in the tire or wheel.

Both of those are the front tires. I’m going to inquire about the road force balancer. If they can’t do it, I’ll look elsewhere.

Obviously I can do his, but I’d rather fix the problem areas of hiding it.
