all will work up to 20 max but purchasing tires in that rim size are going to be expensive. i would go 17s max. The first reason: tires are cheaper, the ride will be much better than 20inch, but this depends on the year of the accord. newer accords come with larger rims(up to 17s), while older models come mostly in 15s. State the year f the accord and then that is the only way you can find out exact tire size then rims.
