I disagree about diameter being inconsequential..When I swapped sizes last
time it added  about ℅10 to my overall gearing, bringing it to
optimum...with the smaller ones (stock 14" standard size) the gearing was
wrong...it worked, but with that 10% change, it is right again( in my
opinion)... I actually put a tape on the two different sizes.
