Alloy wheel upgrade

[Accord tourer]

 spacer I needHi folks 

Wanting to fit some 19" blaze CRV wheels to a 8gen accord tourer, specs show they have the same hub measurement but the 19" alloy has a bigger bore , does anybody know why the 19" blaze alloys bore is too big  and what size spacer I need to make them fit

I only have a tape measure so can't measure them correctly

Hi, have you driven or been passenger in a car with oversized wheels not designed for it? It usually messes up the ride, handling etc so much you never wished you'd bothered...
