This is a dumb question but will a Dunlop D402 Harley-Davidson series tire size MH90-21 fit on a rim bearing a 3.00-21 tire? What does the MH stand for? For the rear 130-90-16, will the Dunlop D401 130-90HB-16 work. What does the HB stand for. Bike is a 2000 HD Sporty 1200XL Custom but has been customized to the point of being barely recognized as a Sportster.
