What size mm rim is a fast back front rim?

[bikebuilder]

I just bought a tire. I thought the ad said 406, but I got the tire and when I went to look at the ad again, it said 451. If I can find a fastback rim will it fit?

I have no idea what fastback rims are in mm there 20 x 1 3/8 but i have my fastback wheels all apart right now if you want me to measure it?

If you don't mind, that would be a great help. Would you mind measuring the rim edge to edge and the tire from the inside diameter bead to bead? Inches are fine.

Thanks!

I just found an ebay listing for fastback tires that mentioned a 451 size, but a double check would be great.

Ya no worries man,

inside/inside of tires is 451
outside/outside of rim is around 464 ish

It is exactly like this tire. It would look great on a fastback!
