DO be careful. I also have an 05 HAH and found a brand new spare at the bone yard,

If you notice, at least in my case, my HAH has 16 inch tires, The 05 Accord that was the spare tire donor had 15 inch tires.

This isnt a real problem UNLESS the flat occurs up front. By having one tire a different size than the other will cause undue stress on the transaxle because one wheel will actually be traveling farther than the smaller spare tire.

The way to get around this is situation is this. Make SURE the spare only goes on a back wheel. If the flat is up front, it will require u to swap the the flat to the back and the back tire to the front in order to maintain same tire sizes up front. THEN replace the flat tire on the back with the smaller spare.

Its an extra step, but I am confident it is an necessary one.
