If you can afford 4 tires put 2 new on front and 2 on the back as long as the tire circumference is close you should be ok on the rear.

After experiencing 1 blowout, and 3 with football-sized bulges on them in the same week I decided something had to change. After I'd changed the blowout, I limped into Chamberlain, SD., found a large truck repair shop on the East end of town. They carried Sailun truck tires, showed them to me, I bought 4, had them mounted, never had a tire problem since. The following time included a trip to Alaska without tire problems.
I've now traded for a DP, sadly Sailun does not make tires in my required size.
P.S. Make sure your rims are rated for 120psi.

Around here some tire stores will not sell you tires rated for less than the OEM tires or a smaller tire. They say it's Federal law now. I don't know if it is or not.

Picture a super low profile tire as compared to a regular tire. The low profile carries much less weight. You do not want a wider tire, just a taller tire.
I have a larger (somebody please help me here with what that distance from rim to tread is called) 16" on the front and carry max allowed psi, and feel much safer with that additional capacity. If I'm going to have a tire failure I do not want it on the front...
Pity those having to pay for those big 22" tires http://www.irv2.com/forums/images/smilies/sad.gif

? What?
A low profile tire carries much less weight?
What are you trying to say as the tire profile doesn't change the weight carried?

I don't know either. Big O tires shop near me would not install a different tire on my Jeep than what the door-post placard stated. I suspect it was their legal dept. speaking.

Same store brand tires, Big O, originally mounted all six LT215/85R16 Load Range E rated at 2,680 lbs at 80 psi. After bad alignment job caused uneven wear, I replaced the fronts with LT235/85R16 Load Range E rated at 3,024 at 80 psi. The difference is 362 lbs per tire, or a total gain of 724 lbs. The height gain from the larger diameter tires raised the front of the coach enough that I had to lower the headlight aiming. From this experience I made the assumption that low profile tires within the same load range would carry less weight. We all know what happens when we assume.
BTW, Big O and their affiliates are widespread enough that service is readily available, and I understand their store brand tires are manufactured by Cooper here in the US. But again, I assume...
