I understand the extra axle but why such small tyres on it and not the same as the other ones?

I'm going to make a SWAG at this. I'm guessing that the weight of the vehicle just SLIGHTLY exceeded (or has the potential of exceeding) the GVW of the single rear axle, so instead of spending the $$$ for a tandem rear axle they installed a smaller tag axle and saved some money.
