Can you mix P225 75R15 on one Axel and P235 75R15 on the other on a 93 Jeep Grand Cherokee with part time 4 wheel drive?

There shouldn't be an issue with it when the two fatter tires are on the rear and thinner on the front, but don't mix them up left to right. We used to do this a lot when driving on sand, we put fatter tires on the front for flotation and better steering.
