[55 Chevy]

For the M/T leakage I tried different brands of Dishwashing soap & also slime. Neither did the trick. Still weeped through the sidewalls. The only thing that sealed them right up was the "original" Coca-Cola(Thanks Don). Poured it on the sides,rubbed it in and let them sit in the sun. Turn over and repeat. Mounted up and no leakage.

My 10.5 x 29.5S C07 Hoosiers do not leak at all with nothing done on the inside.

I have been unable to stop the tire from moving on the rim without screws. Tried dry, Aqua-net hairspray and weatherstrip adhesive. Swapped them and they just repeated the other way. My latest effort is Permatex High Tack brush-on. Do not know if that will do it. I have heard that knurled rims will sometimes do the trick.

I believe the main problem is my old Motorwheel Flys because I know of people with the same class car, with more modern rims that do not use screws and there is no tire movement.
