Got the wheels out, kit doesn't come with any tyres, which, I think, is a good thing, cause most of the time, you never ever use them. Wheels, not to sure what they are made of, they are shinny, white (with what looks like either a red or pink tinge), they are well braced inside, and also come with vent holes too.
Front wheels, do not tighten too tight, as the bearings bind, due to no internal spacer.
