How about a set of these?


I found them on a Case, but perhaps they'd also be suitable for certain German machines

Polaris have a more up to date version on their top of the line quads, pricey though around 1000USD per wheel.Polaris TerrainArmor test ride | Fox News

Not sure how well they handle high speed work though.
Quads and Military vehicles seem to be the main focus.
