Volvo G990 Grader

The optional 20.5x25 tires of the original machine in scale 1:8 (D=186 mm, W=69 mm) do not seem to be commercially available. Consequently I´d have to make them, too. What size would you need, exactly?

Mine is (in scale 1:14.5) D=184 mm, W=72 mm, inner D=70mm. But the hardest part of this challenge is to figure out how soft the tire should be to looks like the real at 1:1...

OK, I forgot to mention that my tires would have an inner D=55 mm. Despite the difference from your 70 mm I'd be very interested in hearing from you if you find some tires or start making them. I fear it will be hard to figure out the appropriate softness without actually making some tires to experiment with.
