Best way to balance 37s

[MonsterBIlly]

I recently switched to 37s. The shop i bought them from used bags of rubber pellets inside the tires to balance them. Most of the time it does a good job. However once in a while when i hit the freeway, at about 65 mph it will start shaking the shit out of me from the imbalance. If i stop and start again usually it goes away and is fine.

Should I remove the pellets and spin balance?

A lot of people go straight to those internal balancing balls on anything over 35”. But 37s and larger can be balanced with a traditional static or dynamic balance using hammer on or stick on weights. The issue is finding a shop that can fit a tire that large on their balancer, if they are even willing to do something outside the “normal” size range. If you call a few shops you should be able to find someone capable. Good luck.

I use balancing beads in my 37s and really like them but you do have to use the proper amount for the tire. Sounds like the tire shop did not use the right amount or the tire has issues. No amount of balancing can make up for out of round tires.

I'd certainly remove the pellets. If it were mine, I'd also see how it rides without even balancing the tires. I've driven in numerous vehicles with unbalanced large tires (35" and Up) and rarely felt any serious vibrations. It can be difficult to truly balance a large tire. However, because these big tires have a much slower revolution at any given speed than smaller tires, the imbalance is often not felt unless you're going real fast (80 mph or more) and I would not want to do that in any lifted Bronco with big tires.

If you air down alot for off roading there is a chance the tire will move relative to the rim making balance weights useless. thats the reason my tires aren't balanced. Was not aware of "marbles" at the time. I would be tempted to try them...

I'm not a proponent of putting anything in the tires...Just don't like the idea of having something moving around in there...

Road Force balancing is what I look for when deciding which business to use. I used to have 38's, back in the day, now running on 35's...

Also, take a look at your tires...is there painted dots, on the sidewall? Yellow, perhaps?
I have learned to tell the person who is mounting the tires to place the "yellow dot" directly over the air valve stem. I have this done for all my cars/trucks...

That "yellow dot" signifies the lightest spot on the tire...and thus should be placed on the heaviest spot of the wheel..the valve stem...

These two factors (road force balancing + "yellow dot" placement) gives you the best outcome regarding tire balancing...IMHO.

FYI: No vibration at 80 mph... ; ) But, the fiberglass hood balloons at the rear corners on each side of the hinges as well as between the hinges ... Yikes!
I'll be installing some hood supports I made this past weekend, to the back area, to hopefully keep the hood from exploding from the air pressure!

Good Luck!

Depends on the quality of your tires. I've found better name brands like BFG will balance out well with just a static balance. I have 37" KO2s and they have no issue doing 85mph without shakes or vibrations.

On the otherhand, I've seen off-brand stuff with visible runout on the balancer. No amount of balancing was going to fix those tires.



Static or dynamic will be better than balance beads any day. I've seen those things chew up the insides of the tire, plus they take a small distance to get distributed and balance the tire from a stop.
