The frame perimeter would be at ~2-10 inches. the largest part of the wheel will be at .5*wheel diameter. In other words, the frame itself has no effect on your maximum wheel size, the vertical projection of your frame perimeter is the limiting factor. that means that a wheel with a tapered tread (allowing it to extend into the corners of the frame perimeter) could be up to 47.2 inches in diameter if it were placed on a diagonal, despite the ridiculousness of such a configuration. Assuming a frame 10 inches off the ground, the wheel, at frame level would measure only 29.1 inches. by lowering the frame to 2 inches from the ground, that number drops to 13.6 inches.
In a far more conventional long setup. 38" wheels would measure only 25.7 inches at a height of ten inches and 12.2 inches at a height of two inches.

If engineers can't say what if, then the world would be a much more boring place. That being said, once wheel diameter gets a little higher than ten inches, making them any bigger would yield a negligible advantage. And that is ignoring the added weight of the larger wheels and the extra gearing needed to bring the motors back into an operating envelope which the electrical system can cope with (without browning out every time you try to turn).
