Nice. How much did they cost?I’ll post better pictures later, but bought Fifteen 52 through Alfa9 supply. Matt was excellent to deal with and took the time to answer all of my numerous questions.
generally one selects lower profile tires so that the overall diameter/circumference is pretty much unchanged.
the lower profile tires typically don't ride as well, but might handle a little better due to the change in sidewall height and flex.
if the 20s on the stelvio quad ride too poorly I may be looking for 19s haha.
