[Closed] Better tyres for Stan's Grails

Evening all!

I swapped the heavy wheels on my crosser to Stan's Grails (hand-made by Mark at Spokesman Wheels - highly recommended).

I put Schwalbe Ultremo ZX (non-tubeless) on for the commute. Great tyre, but they are a massive effort to get on and off. I've heard the Grails can be tight, but every tyre change is a pain and I swap them for cx tyres fairly often.

Does anyone know if this is a specific problem with the Ultremos? They were a little tight on the OEM Giant rims. Is there a better road tyre for this rim?
