I ordered tubes for my riding mower tires and was please with the quality and how fast my order was delivered .I will deal with Jack's again for sure.

I only rated them a four star because it has only been about a month, so I don’t know how they will hold up. Don’t let that hold you back; they seem well worth the money. The tire tube appears to be of good quality. The instillation was a bit of a wrestling match (I won), but that was because braking the bead on the old tires took some effort. The tube went in OK. So far they are holding air and doing well. Very glad I bought them. I should have done it last fall.
