My 17.5's weigh 95 pounds apiece and are balanced with an internal product.
My 19.5's that I have on the truck have the internal product (equal) along with the tires match mounting & balancing, as noted below: It really works, smooth!
Why do new vehicles ride so smooth on their factory tires, yet almost never ride as nice on replacement tires? Because the Factory "Match Mounts" every wheel and tire assembly!
Didn’t you always wonder what those little green stickers on new trucks were for?
The OEM’s use tire uniformity graders costing hundreds of thousands of $$$ to mark the
"high spot" in the tire (notice the green dot) and "low spot" in the rim. When these are matched up, The the wheel run out cancels out the the tire run out and "forces" the tire to become round. This ensures that your new vehicle rides "factory smooth" on it’s original tires.
Our VIBRATION ELIMINATION SYSTEM solves vibration problems BEFORE your wheels leave our shop
Every tire and every rim is out of round to some extent. We measure the "run out" or out of round of the rim using the data arms and dial indicators built into the machine to mark the low spot. We then use the "load roller" to measure the out of round of the tire. A tire may be out of round or have a "hard spot". Left undetected, either would cause a vibration...We identify and fix these problems.
By matching up the "high" in the tire with the "low" in the rim, we use the run out in the rim to "cancel out" the run out in the tire, thus creating the roundest possible assembly. We even go one step further than the factory by making sure that each wheel and tire "belong together". That is, we make sure that the run outs of each component will cancel each other out. If they won’t, then we either reject the wheel or tire as defective, or re-mount the tire on a different rim.
Next, we perform a precision "Dynamic" (weights on both sides) spin balance. Although we highly recommend dynamic spin balancing of your assemblies for maximum vibration control, we can also provide a "Static" (weights on one side only) balance if you prefer not to have weights on the outside.
As a final step, we add a unique blend of Equal Tire balancing compound into the tire. We’ve worked closely with the Equal Engineers to develop a compound that works in our 19.5" pickup truck applications. This takes up for any imbalance, reacts to smooth out differing loads, and keeps the tire in balance for its entire life.
