Well, the nose is too long, and there are other problems with the hull,

but that's a visualisation that works.

+// ISO standard numbers refer to the tyre bead diameter in
+// millimetres; the outer diameter of the rim is about 14mm 
+// more. Rim width varies but 22mm is common. The wheel sizes 
+// I'm interested in are ISO 406 and ISO 451. Fronmt hubs (and 
+// the hubs I'm planning to use are all front hubs) typically
+// have an over locknut dimension of 100mm, but the lefties, 
+// which I plan to use, are narrower: 50mm flange to flange, and
+// 65mm overall (with a 5mm spacing to the inner side of the
+// fork leg).
+//
+// Outer diameter over the inflated tyre is obviously larger than
+// the rim diameter but how much larget depends on the tyre; 
+// for road tyres, 20mm seems about typical.
