No one can balance my tires??????????

[rollingbig]

ok so i took my 37" bf good rich mud tires into get put on my rims i bought them used with about 3/4 tread life left thing is i had it to 2 different shops and they cant seem to balance them at all, they just keep putting on lots of weight, so what about getting them broke down and balancing beeds put in????

[elephantrider]

i have had issues getting my bfg a/t tires balanced as well.
they never get perfect. always some small vibe somewhere.

i have heard both ways on the beads, that they work on some
and some they dont.. ?

[MPD106]

if they cant balance them its becasue they dont want to. Go to Equal's web site (the equal balance bead, not the sugar supplement) and find out how much you need.

no i mean they balanced them and had a ton of weights on there from 2 different shops and its just horrible the vibration and shaking i know they must be able to get better than that lol! im goin to get them to break them back down turn them some and put a bag of balancing beads in and try again thanks for the chart!!

at my local shop they use these bags they rip open and through in the tire which balances them i believe theyll work for you check it out

That is really weird, do the tires look worn really funny or anything? Could be part of the issue. Or they don't know how to balance tires.....

That size of tire shouldn't be a issue, my 38x15.50 nittos mud grapplers have barely any weight on them and not any sort of vibrations.

My 35" bfg mt's ballanced with very little issues... What kind of rims? Weird but yea, try the balance beads might take to bags but the bbs will go where they need too.

It's always possible your wheel/s are bent, happened to me once. On that little balancing machine it read something like 6.00 when it should have been 0.00. Half the wheel had weights on it, luckily the tires were out of round too so the guy spun the tire 180 degrees on the wheel and got it to 3 or so, with about a quarter of the wheel covered in weights, wasnt too bad. Sold that piece of crap shortly after

I would ask around to see what machines people are using. They now have tire balancers with laser alignment and actual tire "road test" features. We recently purchased one of these for my shop Wheel Balancers and Wheel Balancing Accessories from Hunter Engineering Company but I can't remember exact model number.

Basically, you want a shop that does a flawless job and not a cheap place. Weights are placed in two different locations of the rim with newer machines. Right against the back of the rim (closest to the middle) and on the edge of the rim to get the best balance. Steel rims are actually the best to balance cause you just clip those crappy looking lead weights to the lip of the rim.

Also, most tires now have a little dot on them that identifies it should be positioned closest to the tire valve. This helps with balancing as well.

Hope I didn't babble too much.

Have the shop inspect your tires. The 35's that are on my truck now have shifted belts and they won't balance. Had the same issue you're having. I let my cousin borrow them for a while and now they have kind of balanced out. (I'll let him replace HIS wheel bearings. ) They have no weight on them at all and they're pretty smooth all the way up to 90.

ya im going to take them back in ang get them to pop them off and spin them some and put some balance beads in them and try them amd see what happens! and nothing wrong with rims i just took of 38.5 14.5 x17's and not so much as a shake, just like driving a car perfect!!

call your local tire shops. ask if they have a Hunter GSP 9700. this machine can be used to solve uniformity related tire and wheel vibrations, this service is called road force balancing. i had this same problem with my bfg's, they charged me 25 dollars per tire. its well worth it, i chased this problem for 3 months 3 tire balances then i finally found
this service, now my truck rides like glass no vibrations.


hunter gsp 9700 balancer
The GSP 9700 extends far beyond the traditional functions of a wheel balancer and "road tests" the wheel before it's on the vehicle to eliminate vibration problems. Hunter's exclusive Road Force Measurement™ System utilizes a "road roller" to measure uniformity of the wheel and tire, simulating a road force test and verifying if the assembly is "round when rolling."

The GSP 9700 will automatically diagnose any vibration problems. With this machine, we can locate and eliminate virtually every cause of vibration relating to the tire and rim and offer our customers 100% quality control.

What is Road Force Measurement?
couresy of Hunter Engineering
Road Force Measurement

Road Force Measurement? is new to the automotive service industry. This new measurement identifies tire and wheel uniformity, which has been measured for years in assembly plants and manufacturing facilities. Road Force can be used to solve uniformity related tire and wheel vibrations. Tire/wheel assembly uniformity can only be measured under load.

The load roller on the GSP9700 performs a computer simulated "road test". It measures the tire/wheel assembly to determine how "round" the assembly is when rolling under a load. If a tire were not exposed to the road surface, then balance would be more than sufficient. However, not all tires roll round under a load. For example, an egg-shaped tire/wheel assembly can be balanced about its axis, but an egg-shaped tire-wheel loaded against a surface would not give a smooth ride.

To understand the effects of radial force variation on vibration, a model of a tire can be used. The sidewall and footprint can be understood as a collection of springs between the rim and the tire contact patch. If the "springs" are not of uniform stiffness, a varied force is exerted on the axle and causes it to move up and down as the tire rotates and flexes. This movement creates a vibration in the vehicle unrelated to balance.

The GSP9700 load roller applies a force of up to 1400 pounds against the rotating tire/wheel assembly as it performs the Road Force Measurement?. The GSP9700 measures loaded radial runout of the tire/wheel assembly within 0.002". It plots data points as the component is rotated and calculates the radial first harmonic of the tire/wheel assembly and the first harmonic of wheel runout. The peak-to-peak value (Total Indicated Runout) and second, third and fourth harmonics of Road Force are also calculated and used for diagnostics. These measurements are all displayed on other screens.

The measurements of loaded radial runout are converted to Road Force Measurement in pounds, kilograms or Newtons.
