Tire Wheel Assistance Please.

I have a 2014 E4 we recently reworked. We installed a new D&D sealed motor from Syracuse NY. We installed newly refurbished Delta Q and Motor controller. The old girl is alive and well. New brake calipers on the way. I am now looking for tire suggestions.

The manual calls for 165/70/R12. I would be interested in something a bit taller without triggering modifications. A touch more speed wont hurt and a taller tire wouldn’t hurt with the updated motor.

What is suggested for tires and where to find some for Municipal use in a Village in Western NY.
