Anyone know of a tire shop around the atlanta area that actually calibrates their balancing machines? I just had a used set of 315/75/16 inch bfg mud terrains put on my truck and it shakes at all speeds pretty much. The idiots that mounted the tires have 13 oz on each front tire and ran out on space on the rear rims with the stick on weights. (over 12 oz). This is the 3rd set or tires that have shook on my truck. It's a never ending battle with the idiot ******** at tire depot

 

You're going to have a hard time balancing any tire that size. When I balance my Red labels I just get them close, I don't even worry about it.

 

Call around and ask places if they have a Hunter Road Force Balancer. That's probably gonna be your best bet. It's one of the most accurate tire balancers and it will also tell the tech if your tires are no good.

 

They also couldn't balance a set of 265/75/16's, a set of 285/75/16's twice on 2 different sets of rims or a set of 205/60/16's on my mom's Bonneville

 

get them to put bean bags in the tire instead of the POS lead weights.

 

Where do they have the bean bag weights for sale?

here's the link, the tire shops up here put these in standard to any oversized tire.

 

It may not be the balancing that is the issue. It could be the mounting of the tire. They need to watch how the tire rolls. If there is a hop then all the weight in the world won't help. You can try NTB. They used to be good, but it really depends on the tech that is working at the time. They also need to make sure the wheel centers on the shaft. That will also throw off the balancing. Once it is centered they need to spin it on the balancer to see if there are any hops. A wheel hop or flat spot means a new wheel. A tire hop means that they need to mark the spot on the tire and wheel. Break the tire down, turn it 180 degrees on the wheel. Use lots and lots of lube and air it up. Then try it out on the balancer again. If the hop is still in the same spot on the tire then you know it is the tire. Most of the time it will correct the problem. Once the wheel and the tire are rolling smooth then they should try to balance it.

With most modern balancers they can easily be calibrated. Most shops do so weekly. They should recalibrate right away if they drop a wheel on the shaft. That can easily happen with a large truck tire.

With your set up I would expect less than 3oz with those tires and a good set of wheels.

 

i got a bad balance recently at a shop in gainesville. i decided that i didn't want to go back there for rework, so i took them to walmart. they balanced them for $20 and did a good job.

 

Sounds EXACTLY like how my last year has been! I had a set of used 285 Mud Kings put on my truck last year and they wouldn't balance up for **** either.... We got 2 of them down to about 5-6 oz each, but the other 2 were up to over 12 oz like yours, they were so bad that I just told him not to bother putting any weight on them, and threw them on the rear. That truck became almost hellish to drive, shaking the teeth outta ya at any speed over about 80kmh.... I just got em off a month ago, got a nice set of BFGs on there now and it is like a whole new truck now!! Now I gotta change the shocks and other stuff that the tires beat off the truck

I could watch my rollbar in the rearview mirror shake so bad it looked like it was havin a siezure! ok maybe not thaaaat bad, but it still shook like a ****, I'm sure cars behind me could tell
