Heavy walled truck tires are just hard to keep balanced. The weights fly off after a while. Some are glued on some pressed on the bead, but it's a continuing problem. Centramatic automatic balancers have been around close to 30 years. You'll see them on UPS trucks, Hummers in the military and thousands of over the road trucks. Centramatic has sold some in to Mexico used on the drive shaft for the hammers on flour mills. And a few farmers have bought them to balance the main drives on combines.
It's simple how they work. The center disc slides over the studs between the wheel and hub. The outside ring has stainless steel bb's in synthetic fluid. As the tires roll and get above 15 mph, the bb's go in orbit and settle where the imbalance is. In a strobe light demonstration you can see the bb's in clusters where extra weight is needed to balance the wheel. A balanced tire can be 10 degrees cooler on the side wall because of less flexing. Cooler tires wear off less rubber than hot tires, giving you 25 to 50 % longer tire life. That adds up to quite a savings if you have 6 to 18 tires. And Centramatic's can prevent cupping on your steer tires.
The test truck was a 1997 Ford F250 crew cab diesel. With diesels being so popular in the 3/4 ton trucks and larger, the extra weight from a diesel engine keeps your front tires working. The tires had 10,424 miles on them. And as most of these 10 ply E rated 16 inch tires do after a few miles, you can feel the vibration in the steering wheel and notice the extra effort it takes to steer through the gravel ribbons in the road. And that's how this truck felt with 10,000 miles on the tires. We added the Centramatic balancers and you guessed it, the vibrations gone and it steered better. That vibration at the steering wheel does get irritating doesn't it?
Beside reducing your tire heat and increasing tire life, according to Centramatic, the design also helps reduce brake heat and brake dust that transfers to the tires and wheels. These "On Board" balancers will keep your tires balanced automatically as your drive on your truck and trailer. It's hard to keep a tire balanced on the rough roads that a lot of trucks live on. So just after a few months of driving, your tires don't fill new anymore.
Pot holes, gravel ruts and washboards constantly beat on your tires. The heavy duty tires on your trucks and trailers have a deep thick sidewall that takes the first impact from the road surface. These thick tires are dramatically harder to keep balanced than a car tire considering the weight they carry and abuse dished out. I know several folks who just gave up trying to keep the trailer tires balanced. Just a hand full of trailer manufactures balance tires on new trailers. I guess the horses and boats don't complain much in the trailer. But trailer tires will last longer if you keep them balanced. Having your tires automatically balance as your drive makes economic sense and a balanced tire could increase fuel economy.
How long do you think those lead weights will keep that heavy 10 ply tire bouncing down those ruts and pot holes in balance? Come on guess! Centramatic has been in business in Ft. Worth since 1985 and holds over 10 patents in balancers. They come with a 5-year unlimited mile warranty, and they offer a no-risk money back guarantee. These balancer discs will also protect your tires from brake dust and brake heat. Whether you are driving highways or those rough gravel roads. You will be able to tell the difference in handling and driving fatigue.
