I have read all I could find on tire sizes. Either I missed it or did not understand. I have a 2005 Heritage. The OEM rear tire is D401 150/80B16. I am about ready for new tires and would like to got to whitewalls. However the price difference for whitewall in the 150/80B16 is much higher than the D402. Can anyone tell me if I can run a rear tire D402 402 MU85B16, this is the same size as the Deluxe runs. I think the rims are the same. If so how will the mileage compare to the D401? Or are there other suggestion. I will stay with the Dulops since I will not be replacing both tires at the same time. Front very soon. Back will run till later this summer. Thanks.
