Hi I am new to stovebolt. I have a 56 4400 and I was looking for new tires and learned that 8.22.5 tires have been discontinued for many years. There is a metric size that is equivalent to them and is 245-75-22-5. They are too wide and you will need a wider rim. I did get lucky and I found three new 8-22-5s in East Haven Ct. Thanks John
