Have you thought about front chains? That’s all I’ve needed. Plus they are cheaper, lighter, easier to install and don’t have clearance issues.
Wheel spacers can be stock items or made to spec. Typically you will need to know your bolt pattern and spacing. On a light truck it might be “5 on 5 1/2” meaning 5 bolts on a 5 1/2” diameter. In your case it might be metric.....but I’m not sure. With that info you can shop around. Tractor stores and hot rod stores can get spacers and the price varies radically- it pays to get a few prices.
Also check the rim back spacing. If they aren’t centered you may get some back spacing by flipping the rims. For good traction you will just need to drive in reverse....haha
