I want to buy a mini spare tire for my Bronco Sport - the previous years came with a mini spare but according to the Maxxis (tire manufacturer) website that spare is only 25.5" in rolling diameter yet the 22560R18 tires on my Bronco Sport and previous years are about 29.5" rolling diameter. Seems this spare is too small? Any experience with this -
