Oh and take al
Oh and I wanted to point out something in the above photo - the green sticker on the wheel. That's the way Ford has the wheel manufacturer matk the low point of the wheel. Notice it is not at the valve hole.
Also notice the big red dot on the sidewall of the tire. That is likely the high point of the radial 1st harmonic - and how it's really close to the green sticker. That's why this assembly has only 20 pounds of road force even though it's an LT tire and wheel.
Appreciate the discussions/info??
Ironically, I measured runout on that wheel. Very little to even do a "RF' procedure.
I Mic'd all 5 stock wheels, none had much over 20 thousands
(this steel one was the worst, but still really good), especially radial runout (which was typically 10 thou or less).
That tire just happened to be round and "well made". Many of the exact same
tire were made horribly. I put that tire on one of the alum rims (in some random spot),
didn't even run the RF procedure, and it RF'd 7 (the best I got in the final 4. I am using)
Final Right Front
My final numbers on the other 3. (switched this to rear when one other tire came in lower @ 8 #'s)
Left Rear (didn't take pic of rim runout)
Right Rear (eventually switched to front)
You can see the rims were almost "perfect", especially for base XLT trim, cast, run of the mill alum factory wheel.
Not a lot to work with for actual RF procedure.
This was how I got it off the lot.
This was not a matter of improper mount, improper (or lack of RF), poor balancing,
wheels out of spec. This was tires made like crap.
After Ford gave up on me and I realized ONE of the tires RF'd at a really low number
(especially for an LT), I decided there must be more good one's out there.
Of the 6 more that I bought, 2 were pretty good to excellent. 4 were returned and two (originals) I have
sitting out in the barn (hard to throw away new tires, but they are junk). The best one left,
became the new spare. One original tire and original spare were used on truck...
Been looking for a better (used) tire machine for over a year. Something with two "roller bead" disks,
that can press against the tire and make rotating tire on rim easier. All I found were
well used "shop" machine's, most 8-10 grand and 8 years or more old.
Gave up on used, just ordered a new Corghi Master J (wanted to stay with Hunter,
but their new prices are insane). Looking forward to being able to swap ultra low profile
tires and RF procedure more easily.
