I know this doesn't really narrow down the possible tire options for the Jaguar I-Pace, but Michelin has partnered up with the Jaguar I-PACE eTROPHY electric support series. Perhaps they'll be providing tires for the street going models as well.

The concept is using 22-inch wheels and 255/40 Pirelli P Zero tires, I would expect 20" as standard and as far as brand goes it would be up to Jaguar. Porsche bounces around on brands and I'm sure Jaguar will do the same.
