The clearance issue is not with the mudguards.

The 8.25 tyre is both wider and taller. As you turn the steering, a taller and wider tyre will contact the chassis and/or front spring sooner that the 7.50 tyre. This can be prevented from happening by adjusting any steering stops (if fitted) on the front hub, but in any case will increase your turning circle.

The other approach is to alter the centreline of the tyre by using a rim with less offset, or fitting a hub spacer with more offset. Tricky stuff to get right, dabble at your own risk.
