My apologies if this is off topic. I could not find a spot to put it.


My problem is as follows. Some time back, I had purchased a Big Red
Wagon from Northern tools. It has 4 pneumatic tires and good load
capacity. Over the years, It has served me well.

The problem is that one of the pneumatic tires has gone flat

Don't forget to contact the manufacturer.

I had a tire go flat on a HD wheelbarrow.
I couldn't inflate it so I called the manufacturer.
They told me there is no way for a customer to reinflate
the tire, but the tires are guaranteed for life.
All I had to do is wait a few days for a new tire.
