I too have the ZTK and recently bought a winter set. I was considering the OEM 796M 18 Black wheel & tire setup that does in fact fit the larger brakes. I ended up going with a set from Tire Rack.
They came mounted and balanced with the TPMS on Yokohama Winter V905 225-45/255-40
This set has near identical specs to the OEM winter offering. I usually go square in winter with 225 but decided to maintain that performance vibe.
I will be switching next week.
