our fleet uses a nearby Discount Tire with good service. Last time i was waiting there an old fella with a beat to hell motorhome was patiently waiting next to me. He was MF'ing the guys behind the counter because they said his problem tire was not fixable, rotted, sidewalls shot... he was worried they were going to really screw him. When they pulled it around front it was fixed with some decent used tires that they had laying around. He went from 1970's tires to some safe modern take offs..
"No charge sir, thanks for stopping in, enjoy your roadtrip"...
He was speechless..haha
