Non run flats will be quieter, cheaper and give you a little softer ride. Lots of owners have gone the 'no run flat' route and I haven't heard of any that regretted it. If you are concerned about a flat, carry a bottle of 'Slime' or some other tire sealant and a small 12 volt compressor. And welcome to the forum...I personally use run flats since I travel and just turned 80.
When younger I used non run flats.
