All, although I love my 2010 Fit Sport, there is a serious issue with tire selection, particularly for those that live in snowy areas.
Because of all the snow and ice in Maine this year, I decided that I should remove the Dunlop OEM tires, put on higher quality all-season radials.
Other than the Dunlop, which is backordered in many cases, a Honda Fit Sport owner only has two options in the 185 55R 16 size:
Bridgestone Turanzo El 470 ($140 a tire) or a Bridgestone Potenza ($100 a tire). Neither tire is rated well in wintry conditions.
I inquire about snow tires in this size; nobody manufactures them.
I asked my dealership if I could put on a different size tire, and they did not recommend it.
Neither did they recommend a difference size rim.
Please call Honda at (800) 999-1009 to voice your concern about tire selection for the Honda Fit Sport!
