It realy will not hurt anything to put two new tires on the back or front,But I would replace the other two as soon as you could. If the Jeep is all time 4 wheel drive you MUST make sure all 4 tires are the exact same diameter or or at least within 2-3/32" or you will burn up the transfer case and front differential. Due to the difference in size, the tires rotate at a different revolutions making the sensor think the tires are slipping and therefore engaging the 4 wheel drive. If you are on dry pavement and there is no tire slippage like there would be in snow or mud something has to break and it will the the transfer case and differential.
if the studs are not installed they are just like regular snow tires
Although i frequently see vehicles with snow tires only on the drive wheels, it is recommended by all manufacturers that all 4 tires match, meaning that if you feel you need snow tires then you should purchase 4.
Snow tires give drivers a definite advantage when the streets are piled high with snow. Snow tires are different than all-weather tires or mud tires because they are designed specifically to deal with the problems that can arise when there is snow packed on the road.The Average Snowfall in Your AreaOne of the first indicators for whether or not you need snow tires is the amount of snowfall you experience each winter. If you only get two or three snows, you probably do not need to go to the time and expense of purchasing snow tires. Of course, if you live in a remote area and are going to be expected to drive through the snow no matter how deep it is, you may want to keep a set of snow tires on hand just in case. If your area receives snow at least once per month during the winter, snow tires may be a good idea for you.The Distance You Drive DailyIf you live in the snowiest area of the world but you rarely drive, snow tires may not be necessary. If you need to drive more than two miles to work each day, however, snow tires may be crucial for you. Think about how important it is for you to drive through the snow when there is a large snow storm. If you decide that driving is really important, go ahead and invest in a set of snow tires to help you get where you need to go more safely.The Type of Vehicle You DriveSome vehicles can overcome the need for snow tires by being able to perform in other ways. Large 4 wheel drive SUVs and trucks generally have wider wheels with deeper tread to allow them to maneuver on rough terrain. These larger wheels paired with the control of 4 wheel drive can make it unnecessary for you to equip the vehicle with snow tires. Normal sedans and smaller cars that drive through snow should be equipped with snow tires to help them get through the drifts with more control. No matter what kind of vehicle you drive, there are no tires that help when ice is the problem instead of snow.

In some places where it snows alot you have to buy snow tires. So if you have snow tires then yes you can drive if the snow is 8". But if you don't want to buy snow tires, you can get a chain and wrap it around all of your tires.
Fat tires are best in snow.
You can install 4 snow tires but it is really not necessary. Only install the snow tires on the drive wheels.
