Air Shocks

Hey Guys,

I got my new tires and wheels. The front are 225/70/15 on 15/7 wheel.
The rears are 275/60/15 on 15/8 wheels. The rears do rub when I hit a big bump, otherwise they ride fine. Will air shocks solve this? Of so, what shocks would you buy? Thanks for your help. This is on my 66 Satellite.
