If you are still considering chains.... I have used them quite a bit (and hate them, that's why I own nothing but 4WD).... yes, you can run them on the outer tires only, we have done that many times on our work fleet. As Hottrucks said, 35 mph is an absolute maximum speed, and I would advise a bit less. Of course it's important to have a set that fits well. I haven't had them tear up sidewalls, but they can if they are installed too tightly. They do need to be snug though.... and they shouldn't tear up your fenders if you use tensioners (or strong bungee cords) to keep them snug on the tire. If they are flapping around, something is wrong with the fit or the installation, and you may get damage.

Chains are somewhat of a PITA to deal with, but they are very effective....
