Rim Size, Scrub Lines and Airbags....need input please

[thomps92]

Hello, I have AirRide control arms with Dominator 2600 bags up front on my 1983 C10. I am currently running 15 inch rims all around and would like opinions on the minimal rim size to avoid scrub line issues up front. Obviously 15 inch rims up front poses a serious scrub line issue if there were to be a front tire blowout. SO my question is ......What is the minimal rim size to avoid such issues? 17inch? 18 inch? or do I have to resort to 20 inch wheels to avoid serious injury? I was leaning towards 17inch wheels, but after closer inspection it'll definitely be pretty close even with that size. I'm looking out for my safety and my passenger's safety. Thank you for your input
