Tyre profile changing after going tubeless.

I've just gone tubeless and one unexpected result is that the tyre profile is a few mm wider and taller and they no longer fit under the existing mudguards.

The bike is a Saracen hack 1 with 700c wheels.

There is no clearance on the front wheel (pic 2) because the wire supports rub against the tyre, and there's limited clearance at the front fork (4).

On the rear, the issue is that the (in lack of a better term) rear-fork is quite narrow and can't accommodate the mudguard (3).

What I need is a mudguard set which doesn't go through the rear-fork and has a little extra room in the wire supports, or something else entirely if anyone has any suggestions?

The obvious solution is to either go back to tubes (upsetting), remove the guards entirely (not great), or buy skinnier tyres (I like these tyres).
