I must also say, there is very little difference in width between the two. Without a tape measure you can't even tell.
So consider just getting a 110. That size for your application is available in almost all of the brands.
I used Avon on the 19" and Metzeler on the 21" but there are also many others.
Whatever floats your boat.
