I was told by the dealership they would NOT mount my new tires unless I provided them with new inner-tubes.
I bought the tires on-line, had them shipped to their business, and they installed my tires.
Their installation price was the same.
I bought tubes and took them to them the day I had the job done.
I once lost a tire/tube to a screw, in the road, yeah, you could say I got screwed....
It was 4:30AM, on my way too work.
That rear tire went flat faster than I would have ever imagined.
On a surface street at 40, it was really squirrelly, would not like to experience it at 70......no way.
Tubes are cheap, when compared to a ER bill
