Smaller wheel/rim with higher sidewall tire option?

[salvageking]

I've had two or three flats now due to potholes. The low profile tires are starting to wear on me. I'm currently running 245/45-18 Yokohama's.

Any experience y'all have had with either smaller rims/wheels or higher sidewall tires? I've searched the threads but most are about larger wheels (lol, not smaller). Your advice would be appreciated.

Higher sidewalls should also prevent curb rash to our expensive wheels also….

My guess is that we can't go smaller due to our large brakes. Can anyone confirm? Has anyone tried a taller sidewall on the 18's and fitted them without any rubbing, etc?
