I tried equal in one of my suburbans 245X75X16 and was advised to leave
the weights on with 3oz's of the powder. It didn't work,... and they
told me I needed air with no moisture. Well, I don't have
air(compressed) that dry here in FLA, so I worked out the amount of #9
lead shot (birdshot) to balance the tires in my wifes suburban and my
M1009 CUCV. It takes about 5oz of shot per wheel. and costs pennies. On
a trip to AZ recently in my CUCV I noticed above 70mph some vibrations,
but I don't drive that fast very often, usually about 60-65mph and it's
really smooth. Working out the amount is the hard thing, fortunately I
had wheel weights from the original spin balance. I must say,...it's
really hard to take weights off of a balanced tire and put birdshot in
it, but worth it in the long run. I noticed on my 3/4 ton suburban (the
people that balanced the tires when I bought them said they couldn't be
balanced because the wheels were bent) after about 200-400 miles the
tires had become more symetrical, no cupping or uneven wear, they just
looked round compared to weight balanced tires.
I have had a punture and the 'shot' wasn't a problem, the problem is if
you have to use a tube in your tires,... putting each one of the 'shot'
in the valve stem!!! Just kidding, shot probably only works in tubeless
tires, but 'Equal' sure was expencive and I found it took 6oz's per
tire, sand blasting sand would probably do just as well.
