Drywall Screw Destroyed Tire Balance

[the blur]

My truck developed a shimmy in the steering wheel at 40 mph. very pronounced. Found a 1" drywall screw in the front tire. nothing big, just a standard drywall screw. went to tire shop, patched tire from inside, and I watched him balance it perfectly.

 

drive truck, same shimmy at 40 mph !!

went back to tire shop, rebalance all 4 tires, all perfect.

still same shimmy at 40mph. WTF !!!

 

I rotate repaired tire to the rear, SHIMMY GONE !!

 

so my guess is the 1" dry wall screw cut a steel belt inside the tire.

what else could have happened ?????

From my own experience, unless you have a bad rim, the belt is the culprit.

That happened to me one time. The plug that they had put in stuck out just enough to make it drive funny. once the extra rubber from the plug wears down it will drive normal again.

He said the tire was patched...not plugged.

 

Sounds to me like the belt also...

It is possible that the tire is just a bit out of round. It happens. I had a BFG All-Terrain that was so far out it was replaced.

That is possible, but in this case he said the shimmy didn't start till he picked up the screw.
