It’s worth noting that due to brilliant design decisions, the only way to put different tires on it is to replace the whole wheel. edit: apparently this part was not correct, my apologies for the misinformation
Oh okay. So when getting a new tyre to replace an old one, that's the same as a bike, then?
But I think it's still probably right to say that "wheel" would be more accurate when referring to your "spare tyre", wouldn't it? And probably also when talking about rotating tyres?
