I picked up a piece of glass in my rear tire the other day and went to fix it yesterday but found that the sidewalls of the 31 year old Perelli gave away. Fuck! I've got shit to do, places to go, people to meet. I've also got about a gzillion 20 inch BMX tires and tubes in the shed from the grandkids bikes over the past years... Hum...
They fit a 16 inch rim? Yes, they do!
I am certain that this tire is not exceptionally safe as a daily rider, but no more unsafe than the 31 year old Perelli's I've been riding on both of our Pacers since September. It fits and seated perfectly all around. In a pinch a 20 inch bicycle tire will work on these 16 inch rims.
The tire pictured came off a 20" Mongoose. Go figure!
