Product Questions & Answers

Are these tires ok to use on a 21" Model A rim?
By Dennis Kliesen on August 11, 2018

These are a bit larger than the standard 440/450-21 Model A tires. A standard Model A rim is 3" wide, and the recommendation for this tire is 4" to 5". It is possible these might work, but we cannot guarantee this dimensionally or that they will wear uniformly if mounted on a narrower rim.
