Tire repair at Lex Brodies ?

"Ive been told though ....that once a steel radial has its steel strands cut .....they can move around and cause further damage - especially on the handy plug sets and repairs "

That has happened to me before. Any time you plug a tire you risk causing a type of "hernia" caused by damage to the steel belt. It's like driving on a lopsided tire. Once this happens the only thing you can do is let a bunch of air out and drive the under inflated tire to a tire store, or put the spare on.
