What @laner said. When I got mine direct (sans wheels) Jumbo told me he contacted Schwalbe about an urban 451 tyre but the quantities required were too big.
The Arisun XLR8 is only one I know of which is a bit fatter, otherwise there's a Kenda and the Schwalbe Shredda. Get @broken_777 to build you a 406 on a BMX rim.
