From my blog post "BMW i3 Tires and Wheels: What you need to know":
"The standard wheel on the base Mega World interior is a BMW i Star Spoke (Style 427) wheel that is 19" x 5" on the front and rear and they use the 155/70 R19 84Q Bridgestone Ecopia EP600 all season tires that were specifically designed for the i3. Here is where is starts to get tricky. If you get a BEV i3 with the standard Mega trim, the wheels and tires are the same size on the front & rear, but if you get any other interior trim (Giga or Tera Worlds) the rear wheels are slightly wider (19" x 5.5") and the tires are wider and lower profile (175/60 R19 86Q). Also, if you get the standard Mega World trim but get the range extender, you also get the wider wheels and tires on the rears. Then there are the optional 20" Double Spoke sport wheels. They are also staggered in size and use Bridgestone Ecopia EP500 summer tires, not all-seasons. Up front you get 20" x 5" wheels and 155/60 R20 80Q tires and in the back there are 20" x 5.5" wheels and 175/55 R20 85Q tires."

The tire prices aren't as bad as many predicted. You can buy a complete set of the 19" all season i3 tires (Staggered with the larger rears) for $623.34:

Once the vehicle has been in the field for awhile, it's likely other manufacturers will start to produce that size. The whole market isn't very big at the moment, and considering the vehicle isn't really designed for track use, a good, low rolling resistance tire with decent grip and comfort is all most people will need, limiting the demand further. Being a light vehicle, the tires are likely to wear well, so having to replace them in the short term is not too likely either unless you got a flat. It's not like it's an M-car with performance suspension and tires expected.
