I had small tires on a small trailer which I changed out. I kept one as a spare but it wouldn't seat on the bead and it would be flat in a week. I wanted an inner tube put in for a spare tire. I bought my size online. I went to my local Pep Boys in Indio CA. and I had bought all 6 of my Michelin for my Dually there because they had a great sale at the time so I went back to have them put the tube in this tire for me. After waiting 15 min, they said they can't install this. I asked why? They stated no one there knew how to do that. I said you told me when I got the tires for my truck that you had mechanics there with 30 yrs experience. They never had a bicycle? I said you don't inspire confidence for my Truck tires at all. I got another tire shop to install it, however it is for a spare and will work well if needed. Don't go to Pep Boys Indio CA.
