40 years ago I would scrounge pairs of tires behind the big box tire shop And take them to a gas station 5 miles down the road and sell them for 10- 15 bucks a peace. All on the way home.Reusing factory barrels;
We used to,cough,cough get motorcycle sportbikes tyres from local dealers take off piles. These tyres had the centers gone BUT,the edges were as new.We'd mount'm up,run them at race pressures and get a weekend's worth of hooya's out of them,dragging knees.
So,some folks may not know how to get certain parts to function in the extreme but be careful lumping everybody in the same pile.
If you got a stubborn remington the vise that great scott shooters sells is the easiest thing ive found
