That depends on the vehicle. Most do not require more pressure in the rear tires. The air in the tire supports the weight of the vehicle. A tire is really just a fancy container for air. Adjusting air pressures changes the load carrying capability of the tire. Vehicle manufacturers set pressures to optimize the load capacity and performance of the tire for each particular vehicle.

There's a down-side to too much weight in the trunk of your car. For the sake of argument let's assume you have the same exact all-weather tires on all four corners of your car. You've just added 80 lbs. of sand bags in the back of your trunk. You will find that a car with rear wheel drive will have more traction while driving in a straight line. What happens next is not pretty. Lets drive around a corner with your newly found confidence the rear end will stay behind you. All of a sudden you hit a patch of ice. The rear end will actually step out on you faster with the added weight. The over steer will be violent. You may even do a 360 so fast you didn't know what happened. The weight in the trunk makes the rear end whip outside the turn.
To make the added weight work correctly narrow studded snow tires will provide less surface area so that the tread bars and studs press the road much harder. You can back off the trunk weight to 40 lbs. and you'll feel as if you can climb a wall.

im just going to assume it has to do with weight. the front has engine. and the has nothing. plus theres more seats in the back which could make the tire need more pressure. and more pressure gives it better traction because it isnt sliding around. not 100% sure
