I have 5100's in front and rear, fronts at 2.5". Ran may falken 265's for 2 years without a single wobble.

I too modded the liner and removed the mudflaps

I know this is a longshot but I recently removed the toyota logo centercaps on the rims prior to installing them....possible can be related to the wobble?

No, shouldn't cause a problem. I ran my stock rims with no centers and now with my aftermarket rims with the ATX tires I run them without centers, but I did run them with the centers for a couple days. Doesn't make a difference at all. Just aesthetic.

32 seems low. For C rated I run 40psi.

used to run 40 for c load 285, dropped it down to 35/36 for the last few thousand miles and havent noticed any issues with wear and the ride is significantly better.

So many topics about this issue, I wonder if there has been any analysis on the wheels? The stock Toyota wheels and SCS are manufactured by the same company. I have SCS wheels, I have had balancing issues with KO2's. However, it's not 100%, I have had 2 balances work just fine and 3 that were off. Was it the person, tire or wheel, seems like a mystery still.

Agreed. After all the reading I did before buying, I was positive that I wouldn't have any rubbing with 265s. At least it's a fairly easy fix, I don't think I'll have to trim the fender but definitely move the liner forward. It only catches in reverse, but not at all going forward.


It could be a combination of those things, actually. Bigger tires are always going to be harder to balance, especially the more sidewall there is. I worked at Discount back in the day(03/04), and always hated balancing the 38" tires on like 15" wheels. It can take a lot of time, and some guys wouldn't have the patience to get it perfectly balance, so if it's "close enough" they'd send it out. Most of the time, though, it was either the wheel or tire being the issue that kept it from ever balancing on the machine.

Just a final update, ended up getting them balanced on third try.

Shortly after my driver side front caliper froze up causing tremendous shaking off the steering wheel.

Thankfully was within a few miles of a local shop to get the caliper replaced without causing too much damage.

My gut is telling me the Grabber's were balanced the whole time and it was just the caliper on its way out.

You can "balance" almost anything. We have a saying in the driveline industry. It goes, "You can 'balance' a banana, but it still doesn't mean it's going to run right'"

Translate that over to wheels and tires. Road force is the only true way to see what's up for potentially square/out of round tires.

Discount uses road force balancers, so the wheels/tires wouldn't ever balance if there was an issue with the wheel or tire. I'd say most of the time, it was the wheel being jacked up that was the problem. New wheel, same tire would balance perfect on the first attempt a lot of times.

The huge, aggressive mud tires on tiny wheels were also an issue to balance. I think it's probably just due to pure physics. The diameter of the wheel is so much smaller than the tire, that putting weights on the wheel seemed to do nothing to all that rubber spinning around it. The weights, ideally, need to be as close to the outside edge as possible. Big wheels with low profile tires are cake to balance, but once you start adding a lot of sidewall, you run into the issues.
