They'll be just fine. The rim width will be a little wide for the 225's but certainly within the acceptable range, assuming stock size rims.
You may notice a skosh more accurate handling with the skinnier tires on the relatively wider rims than the 245's, because the tire sidewall is already stretched across the rim effectively pre-loading the tire for cornering. Maximum grip won't be affected much and is really a function of tire compound and tread design. On a truck you have nothing to worry about.

The lighter tire will increase acceleration due to decreased rotational mass and improve the ability of your suspension to keep the tire on the road.

Happy trails!
