CENTRAMATIC Wheel Balancers (370800)

So I bought these for a surplus HMMWV I bought. Tires are a bit out of round from sitting so long. The speedometer needle bounced all over the place, like 10mph range at highway speed.I swapped the rear tires for some off a trailer, brought the speedometer needle movement down some.Bought these wheel balancers, and now at cruising speed the speedometer needle has little to no movement, the ride has smoothed out considerably for how out of round the front tires still are.Very good product so far after 500 miles of driving on them, and I've recommended them to several other people.Just keep in mind these ONLY work for issues with tires being out of balance. If there is some other issue going on with your vehicle then these won't fix it, at best it might reduce some of the symptoms like it did for me.Another way to view it, especially for military 2 piece rims, those tires are a pain in the butt to balance, with the Centramatics you'll never have to worry about balancing them again (provided they aren't WAY out of spec) and the cost is the same as getting the tires balanced a couple of times IF you can find a shop that will do it (Les Schwab tire balancers are only good to 150lbs, the HMMWV military wheel/tire/runflat assembly is 165, so too heavy for their machines)

Continuously balanced tires reducing wear

These things work great on the bigger wheels love them

This thing is awesome! It cured my tire balancing problems. I have 37" run-flats and could not get them balanced otherwise. I highly recommend this item.
