Tire Balance Issues, Need some help

I agree... The tire shop does not have a road force balancer there for the tires are still out of balance. However you have me scared now lol. My tires now have close to 5000miles on them and have been unbalanced from the start and I cant get them done for another 2 weeks. I hope I haven't already created a problem (uneaven wear) .

 

KO's can be notorious for being hard to balance. Mine have had a slight shake since day one. Last time buying these tires for me, overpriced for low quality. You'd think after 30 some years of the tire being around they'd have it fixed by now but guess not. BFG lost a customer with me, I'm going with Wranglers next.

 

Have you checked other places?

 

Where else is there to check? I have new leaf spring, new shocks, new hardware and brakes aren't dragging

 

Meant other tire shops, the one I worked in back home had a balancer with road force while other shops in the same chain did not.

 

There's also static vs dynamic (spin) balancing. There are a couple companies out there that required 1 vs the other for warranty claims. With the back end still jumping around, odds are either you have more than 1 corner that's out of balance, a bent wheel, or possibly a bent axle. But since you didn't have front end vibration before, odds are you didn't have a problem that you moved to the back axle. So low odds it's a bent wheel etc. New shocks and other hardware limits the possibility of general shock etc failure. So that points back to axle or driveline imbalance, failing ujoints etc.

Any kind of harmonic imbalance will generally fluctuate on rotation speed. So smooth at 60mph, all over the place at 70, smooth again at 80 etc. My last out of whack tire was a long time ago and was out of balance at normal highway speeds, which is where I drove most of the time. So I could go slow and be irritated, go at the correct speed and be irritated, or speed and be happy again. So I sped a lot

A bent part will usually be rough no matter what the speed, it's always bent and just gets more noticeable the faster you go.

The roadforce brand balancers are generally most useful on low profile tires where sidewall height is minimal. On a standard truck tire, good chance it's just extra money being spent.

 

I just realized what you ment after sending my post lol. Yea there is another shop that has a road force balancer, but I know the guy at the dealership and he knows whats going on. I'd rather him look at it thoroughly then take it to a shop iv never been to and hope they are diligent and find the problem. I have already dealt with a shop that said there's nothing more we can do and tried to convince me that my tires are perfectly balanced. Rather go the extra mile for peace of mind.

However I just dont want there to be damage done to my tires from here till two weeks

 

If you have 5k on them already, the next 2 weeks won't matter.

 

Having 35's makes it a whole lot harder to balance.

I've never criss crossed my tires. I always go front to back and I've never had any problems with wear from doing that. That doesn't mean you shouldn't do it...and doesn't mean the tires can't handle it. Tires of today are recommended to be criss crossed. However - in situations like this where you've hit a brick wall and can't figure out what the problem is..... Putting the tires back on in the 'direction' of which they started, might help troubleshoot. The theory behind not criss crossing them is....the internal belts (whatever they are made of) can develop a wear pattern going in a certain direction. When you criss cross them...it goes against that pattern. Obviously, doesn't happen to everyone but something to think about..... weirder things have happened.


You mention you have bouncing in the rear AND a vibe in the steering wheel??? So, you have problems in the front AND REAR now?

 

Yes a slight vibe. I think all the tires are somewhat out of balance and the front keeps it quite for the most part because of all the weight. The rear is worse due to lack of weight

 

pretty sure he meant that they just flipped the entire wheel/tire around (backwards on the balancer) and not broke the bead. I hope...

Another product is Ride-On, I use it for my motorcycle tires (no balancing/weights used) but you would need about 2 bottle per wheel in a 35" and it's not for TPMS (although I doubt you have it anyway)

 

What im reading is that the tires have been rotated but the issue youre experiencing is still isolated to the back wheels? That would rule out something that is wheel or tire related if its the same after rotation. Is it on both sides evenly or more on one side?

Youre using custom wheels, which are usually heavier, all terrain tires, which are worse at high speeds then street tires. Have you had the opportunity to remount the stock wheels, even if just the rears to see how it changes the condition?

If this was a car, i would look to rebound control and alignment. That would include items such as blown shocks, as well as worn or broken sway mounts and control arm bushings, or worn wheel bearings. Anything to allow variations in the rear geometry. Being a truck a lot of this is eliminated with the solid axle.

I think its time you get an alignment done. The tech will be able to check of play in bearings or control joints (in front). Before this at least try the old wheels on the back and see what happens.

 

Are the current wheels hub centric??? If not that could be it right there... A quick change back to the stockers could be the tell all as mentioned above! Doesn't rule out bad tires but a good starting point...

 

Ahh, good observation! That would produce a similar condition to a bad hub or loose wheel.

 

Thanks for all the replies guys! I went to the tire shop today and had all my tires filled with balancing beads. I was a little doubtful at first. How can 8oz of beads solve a balancing issue for 35's lol. Drove it home and problem eliminated . And the best part, never have to go back for a balance ever!!!

 

Balancing beads?

 

Are those beads metal or plastic?

My money is still on non hub centric wheels causing the problem though, especially since you still had strange whobbling after you did the rotate and picked it up in the front as well.

 

Yea google tire balancing beads. There pretty sweet. IV heard of them before but never used them till now. Iv heard people using water as well... To redneck for me though lol

 

There hubcentric wheels though. Only reason I'm kinda filling out the wheels is because iv had these wheels mated up with cooper stt M/T and I never had an issue with bouncing like this. The bouncing all started when I switched to A/T tires. I asked the same question as to why I feel this bounce now with new tires and he said its due to a different tread pattern

 

Ah, got ya. My $ would be gone! Lol
