800lb is a perfectly normal capacity for anything built on a passenger car platform. Considering the bolt is a subcompact I'd actually say having ~800lb of "OEM approved"[0] capacity actually seems pretty good. I suspect most of that stems from having to build a beefier car to carry around those batteries 100% of the time while not having an unreasonably short service life for suspension components.
In showroom configuration 99.99% of vehicles are only spec'd with tires that barely exceed the GWVR.
That said, with a pneumatic tire you can just air it up higher than the OEM tells you to and you're good for more GVW at the expense of the tire wearing faster. Obviously you need to be reasonable about it but tires are pretty durable even over their stated weight rating as long as you don't run them hot (airing up reduces flex therefore reducing heat).
It will be very interesting to see if they come out in other sizes/capacities. They already make similar tires for off road use but they aren't suitable for road speeds (go figure)
