Centramatic Wheel Balancers

[beanious]

Hello all, I was having some trouble getting my tires balanced. Running 37" humvee tires on aluminum American Racing 16.5 8-lug wheels. So I took them in 4 times to different shops, trying to get them balanced. Sometimes they would balance them and call 'em good. Sometimes they would say they were way too far off and couldn't be balanced. Some small shops and some big shops, I even got them road force balanced. The tires had zero miles and were manufactured in 2018, with whiskers still on them. Everytime they would shake violently after 55 mph.

I got to doing some research and found out with a dial indicator you can detect the high and low spots of a tire and rim. Then match them up to get the least runout, to get a better balanced tire. Sometimes you can go by the dots on the tires but it varies by manufacturer, etc. So its better just to find the high and low spots and then have them mounted and matched correctly to get the best runout. That made it a better. With the axle jacked up and the car in gear I could see the difference and the measurements confirmed that I cut the runout in half. Two of the tires were mounted by the tire shop in the worst possible spots...

The next part was to remove the wheel weights and install the centramatics. I have to admit I was skeptical about them at first. I'd never used them, but 37's aren't cheap and I figured what the heck I'll buy a set. Wow they made a difference, I can drive at 70 mph down the freeway with no shake or vibrations, acceleration, deceleration and turning is smooth. The best part is if I ever have to change the tire or I get a different set I don't have to re-balance ever! I don't have to worry about throwing a weight or rebalancing later on either because the centramatics dynamically balance the tires.

I can't say enough how thrilled I am to not have to buy another set of tires like what was recommended to me by two shops. I hope this helps someone else out there with large tires that is having difficulties balancing them.
