Managed to get the front Porc on. This tyre was far and away the driest and most crumbly of the two so the other shouldn't be quite so difficult.
Famous last words I know.
Certainly couldn't ride the bike with these tyres, you can see the inner tube in places through the skinwall! So will have to see how long they last. Quite possibly I'll come back to my office in the morning and find bits of exploded white Porc all over the place
Will take some better pics for sure - but here's the Ultimate with white Porc's front and rear. It was starting to get dark so apologies for pic quality, but I love the mix of turquoise, 3DV, white, pink and fluoro yellow!
