In addition to allowing for more payload, the bigger wheels might have more braking power. (I'm not sure about this... but if the number and magnetic power of the components are the same, mounting them on a bigger radius makes them more effective.)
If all the components of the brake system are the same, the bigger tires would give you LESS braking due to the larger radius of the tire. (Leverage is greater the larger the radius.) The difference would probably not be noticeable, but the larger the tire, the harder the brakes have to work to stop it. Ask some of the guys that put huge tires on their trucks and then they can't stop as easily as before - then they have to get bigger brakes or put on disk brakes. In our state, Washington, if you put the big tires on and get in a wreck, you're at fault even if you're in the right because the cops assume that if you hadn't modified your truck you could have avoided the wreck. A friend of my son's found that out the hard way - got blamed and had to pay for somebody's car that ran into him.
