Sorry, but you missed the single most important spec on the sidewall, and purchased the incorrect tire for your application. That no one has mentioned it is troubling.
A 145/80-13 71T can only carry 761 lb. Honda says you need 79T rated tires one that can take a minimum of 963 lb. There's an awful lot of latitude with tires, but none here.
And to those bemoaning the lack of narrow tires, this is why. Load rating depends on the air volume inside, so conventional small tires can't carry heavy loads. Make it a larger wheel, and the narrow tire now has some internal volume, and load capacity.
The 155/60-20's on the BMW I3 have a rating of 80Q. It can be done.
Have fun,
Frank
