Bringing this bad boy back from the dead I know, forgive me...
If you want to go with a stock width 9 inch tire in front and 11 inch in rear, would I be looking closer to even with 5+2 on both the front and rear? It looks like most guys are running 10 inch tires all the way around and the general consensus is 1inch spacers in the rear will even it out....
Does math work?
I don't know how consistent Honda isover time with the size of wheels that they ship, but with my 2016 P1k-5D, the aluminum wheels were
14x6.5 in front, with "4.5 + 2" offset, and 14x8 in the rear with "5.5 + 2.5" offset, give or take a tenth of an inch or two.
When I put 10" actual-width tires on 5+2 rims in front, no spacers, I get 64" wide to the outside of the tires, top to bottom, with a healthy spring pre-load.
Outside-to-outside tire measurements are susceptible to suspension loading, particularly if you measure at the ground. At-ground
measurement of rear tires in pic are 66" top and 63" bottom, with 10" actual-width tires on [edit: 5.5 + 2.5 (factory)] rims, nospacers.
(I originally posted "5 + 3" for the rears.)
