A thing I thought about to get wider tyres under the back of my Ranger project truck was to get two sets of bed fenders - and then slice & weld them so that they went out wider....

If a set were halved with a saw - a strip of metal could be welded too -

But braces might be needed to prevent the weld seam from breaking

Food for thought

It may take extraordinarily wide tyres to get all of that power to the ground in the form of traction, given that the truck is so light and small...
