Because the sizes are correct.

The grey tyres are 2.50 x 4 -- which is 2.5 inch x 4.

You're front tires caster forks will need made to fit the tires you think you want to use. The back angle also might have to be made to accomodate the motor length. Check on that because if will be higher it will be equally larger in all directions, make sure what ever you do accomodates everything in its swing diameter.
Your drive wheels "sounds" a bit easier. The difference in speed will be minimal but traction "I think" will be better, especially off the Tarmac or concrete, if this is something you want to do. Will they rub on the back side because of any added width or if they become underinflated. A shim similar to what the Burgerman has might become necessary. This will add to the overall width of your chair. You have to decide on that. The fenders probably can be adjusted or simply eliminated again tha'ts your decision/
Power wheel chairs are constructed to make ANY home grown modifications difficult, if not impossible without taking many other things into consideration.. You are restricted to using the more expensive grey wheelchair tires, they obviously have made them in fractions of normal sizes, so you run into this sort of grief no matter what your desires are.
Are these things stuff that is worth your efforts, to fill your desire to modify your ride? I think the rear tires will soften your ride. The added diameter to the front should make going over some objects easier. The marking of floors is a small issue except for the misses, and overall you make your ride better. But it is your choice. Perhaps you are comfortable with what you have otherwise.

Is that Brit Law, or rules of your National Health insurance, that paid for your chair? Noone could have ever updated a power chair more than the Burgerman so there is some flaw to your blanket statement. Or have you missed some qualification to it?
In the States you can modify just about anything to suit yourself. But on some occasions you run afowl of the law, like the clean air act which has nothing to do with power wheelchairs. But more often you run afowl of the Warantee conditions when you purchase the item, that misrepresents the law, but it does legally nullify the warantees.
I know nothing about the Fusion !
