I got a tube today for the front wheel on my Rover Ranger. I looked at the packet and it looked like it had been sitting on a shelf somewhere for 25 years. I put it on and pumped the tyre up to about 10psi and while I was standing there it went woosh and deflated. Pulled it back off and it had split on the seam half way around the outside. Seller has said they will replace it but I hope it is not with another old one off the shelf
